ThingCharger Eliminates Cable Clutter

Posted by Andrew at 10:08 PM on March 5, 2014

ThingChargerDevice chargers are the bane of modern life with a complete rat’s nest of cables and connectors behind the average desk. Todd chats to Seymour Segnit from ThingCharger about their Indiegogo campaign for a cord-free charger.

The ThingCharger plugs directly into a power socket, with the device’s charging connector on the top of the unit, and pass-thru power outlets meaning that you don’t lose the socket but even more cunningly, you can stack the ThingCharger to charge multiple devices at the same time.

A range of interchangeable charging connectors - Apple 30-pin, Micro-USB, Mini-USB, Apple Lightning - will be available so that different devices can be charged from the same charger and cleverly, the connectors can be stored in the ThingCharger so they’re much harder to lose. It’s brilliant all round, so much so that ThingCharger raised nearly $650,000 against a £25,000 target.

ThingCharger is expected to be available in Q3 of 2014 and you can pre-order now for $29.95.

Gigabit Powerline from Trendnet at CES

Posted by Andrew at 8:37 AM on January 5, 2014

TRENDnet LogoNetworking over electrical power lines has come a long way since the first HomePlug specification back in 2008 which was was rated at 14 Mb/s. Today network specialists Trendnet have announced a gigabit class, Powerline 1000, with the launch of the TPL-420E2K adaptors.

Trendnet Powerline 1000Based on the HomePlug AV2 standard and using MIMO techniques originally used in wireless data transmission, Powerline 1000 doubles the speed of the previous implementation.

Zak Wood, director of global marketing of Trendnet said, “Trendnet’s TPL-420E2K is designed to easily handle multi-HD streams in a busy connected home.

For the first time, Powerline products use all three electrical wires: the live, neutral, and ground (earth) wires. MIMO technology sends information over the fastest two out of the three available electrical wires. If a user lives in an old home which is not cabled with ground wires, the maximum throughput is reduced from 1,000 to 600 Mb/s.

The TPL-420E2K connects over electrical lines for distances of up to 300 m (a little less than 1000 ft), which is roughly the size of 5,000 square foot home. Powerline 1000 is compatible with existing Powerline 500, 200 and HomePlug AV rated products but when connected to a lower speed adapter, speeds are reduced to the lower rated adapter.

As you’d expected, the communication between the adapters is encrypted and to reduce energy consumption, the TPL-420E2K units go into standby mode when not in use.

The MSRP is US$169 but the Powerline 1000 units are not expected until June 2014. I’m looking forward to testing these already, especially if Trendnet produces an adaptor which incorporates a fast wireless access point.

Mugenizer N11 Qi Charger with Battery Review

Posted by Andrew at 6:14 PM on November 28, 2013

Mugen Power Batteries LogoHere on GNC I’ve reviewed a succession of USB rechargeable battery packs and I’ve tested a couple of Qi chargers for my Nexus 4. Now for the first time I can review both at the same time with the Mugenizer N11 Wireless Charger Power Bank. Fundamentally, it’s Qi charger with a built-in rechargeable 4800 mAh battery. Genius!

Mugen kindly sent me an N11 as soon as it was released and I’ve been using it for about a week or so. First impressions were good as it came in an attractive card box which smoothly slid open.

N11 Box

The box holds the N11, a USB-to-microUSB cable and a power supply, all in matching white.

N11 in Box

The N11 is made from a hard shiny plastic with a rubber ring in the centre to help hold the charging smartphone over the Qi charging spot. There’s a row of charge lights on the top surface and one end has the on/off switch, charging USB port and recharging microUSB port.

N11 End View

If you are wondering how big the N11 is, it’s almost exactly the same size as a Nexus 4. Here’s mine but note the Nexus is sitting back on the charger a little bit.

N11 and Nexus 4

Enough of how it all looked, how well did the N11 work? Frankly, it worked great. Unlike some of the other Qi chargers I’ve tested, it’s easy to spot where the Qi charging coil is. This makes aligning the phone with charger really straightforward and there’s a beep from the N11 to let you know everything is lined up. Here’s a screen shot from Battery+ showing the excellent charging rate.

N11 Charging

The N11 worked equally well with devices that needed a USB cable to charge. The battery is 4800 mAh which means you could recharge most modern smartphones twice from flat. Generally I was able to recharge my Nexus 4 three times from around 20%. The N11 supports charging from the USB port and the Qi charger at the same time, which can be handy. The port is rated at 1 A.

My only criticism of the product is that it was sometimes difficult to pick out the exact charge level on the blue LEDs as the light bled from one to the next. Is it fully charged or 90%? As the power level fell, it was easier to make the level out.

Charging lights aside, this is great product and it’s now my main charging device for my Nexus 4. It’s pricey enough at a nickel under US $70, but the combined Qi charger and battery pack make this essential for anyone who has a Qi-equipped smartphone such as the Nexus 4 / 5 and  some of the Nokia Lumias. You can use the N11 on your desk or on the go. Recommended.

Thanks again to Mugen Power for the review unit.

Practical Meter for USB Charging

Posted by Andrew at 5:09 PM on November 13, 2013

Practical MeterWith the plethora of USB charging power sources and charging rates, it was probably inevitable that someone would develop a meter to measure the power going to a device. The bragging rights go to Utah-based Power Practical and the Practical Meter, a USB in-line power meter. Looking much like a USB dongle, 5 LEDs show the power transfer from 1 W up to 10 W.

Originally a Kickstarter campaign that met its funding back in the July raising nearly $170,000, the Practical Meter has been today recognised as International CES Innovations 2014 Design and Engineering Awards Honoree.  “Just last week we shipped out the 10,000 pre-order units we received during our Kickstarter campaign to have the Practical Meter come to market,” says Matt Ford, CEO of Power Practical. “It’s crazy that a week later we’re being honored by something as prestigious as the CES Innovations awards.

As a pure USB device, it will work with anything that charges via USB such as smartphones, mp3 players or battery packs. Practical Meter is available now for $24.99 online and includes a 3-in-1 fast charge cable with mini-USB, micro-USB and Apple connectors.

Verbatim Dual USB Power Pack Review

Posted by Andrew at 5:17 PM on September 30, 2013

Verbatim LogoVerbatim will be known to many older geeks for their floppy disks but since the demise of this market, Verbatim have branched out into newer media, products including lighting and water filters, and accessories such as USB power packs. Verbatim have an extensive range of rechargeable packs from 1,200 mAh up to 10,000 mAh and on review here is their Dual USB Power Pack with a 5,200 mAh capacity.

First impressions are good. The Power Pack comes in attractive, easy-to-open packaging that doesn’t need to be attacked with a pair of scissors. Inside is the Power Pack, a short USB to micro-USB cable and instructions. The USB cable is only 10 cm long and can be used for both recharging the Power Pack and charging other devices. Some might quibble about the length of the cable but I think it’s handy and avoids all the disentangling. Besides, I have loads of long cables should I need one.

Power Pack Top View

The body of the unit is about 7 cm wide and 11 cm tall. Depth is 1.7 cm and tips the scales at around 175 g. The top and bottom faces are covered in a soft-touch rubber coating and the middle section seems to be metallic-looking plastic. On the bottom, there are four small nubs for feet and the top surface has four blue LEDs and a small button. Pressing the button for a couple of seconds illuminates the LEDs to show battery charge level.

Verbatim USB Ports

Round the edge are three USB ports, 2x standard and 1x micro-USB. The latter is used for recharging the Power Pack and the former for charging other devices. In common with similar products, one port is rated at 2.1 A (port A) and the other at 1 A (port B). However, unlike some of the Power Pack’s competitors, both USB ports can be used to charge while the device itself is being recharged.

The Power Pack is a 5,200 mAh unit which Verbatim suggests on the packaging will recharge a smartphone 2.5 times. My experience with recharging a Nexus 4 (2,100 mAh internal battery) is that this isn’t too far from the truth. Further, the blue LEDs are good guides to the battery level – consider each LED as 25%, so all four is 100%, three is 75% and so on. Below is the obligatory screen shot from Battery+ showing the charging rate for a Nexus 4, which is pretty much the same as charging from a mains charger.

Nexus 4 Charging

In summary, the Verbatim Dual USB Power Pack is a fine little unit. The soft touch rubber coating gives it a slight softer feel and the recharging-while-charging is a worthwhile feature. My only concern is that I think the Power Pack is a little pricey at an RRP of £41.99 and there are other models out there that offer more capacity for less money (but do watch out for those batteries which can’t charge and be recharged at the same time). As this is a brand new product, no “street price” has emerged but something around £25 would make the Dual USB Power Pack value for money.

Thanks to Verbatim who kindly supplied the Power Pack for review.

Mugenizer N11 Pairs Qi Charger with Battery Pack

Posted by Andrew at 5:39 AM on September 20, 2013

Mugen Power Batteries LogoMugen Power are no strangers to innovation but their latest product is genius. The Mugenizer N11 equips a USB battery pack with Qi wireless charger to provide charging on the go. As a user of both types of device on a regular basis, I think this is an excellent idea. It’s also going to be a big win for people who hotdesk and can’t be bothered with plugging and unplugging chargers each day.

image

As you’ll see from the picture, the unit looks much like any standard USB battery pack, albeit a fairly good looking one, with a charging port and power level indicator. The battery has a capacity of 4800 mAh which will fully recharge the average smartphone about twice. The Qi charging plate is on the top and should work with any Qi-enabled smartphone like the Nexus 4. According to the spec, you should be able to charge from both the Qi plate and the USB port at the same time.

The N11 is priced just under US$60 which includes a $10 early adopter discount and free world-wide shipping. It’s pricey enough and you probably could buy a battery and a charger separately for less, but the sheer convenience of a single unit makes it worthwhile. The N11 will be available in early November and I’ll try to get one for review. More information then.

New Trent iCarrier IMP120D External Battery Review

Posted by Andrew at 3:58 PM on May 16, 2013

The fast processors and large screens of modern day smartphones draw power like it’s going out of fashion. A battery that would have lasted several weeks in the Nokia 6210 now struggles to get through a day of calls, email and web surfing. And that’s before starting to play Ingress.

Desktop chargers have their place but sometimes it’s not possible to get back to a power outlet to plug in. External battery packs and chargers fill this space and on review here is the New Trent iCarrier IMP120D external battery and charger. With a 12,000 mAh battery, it’s roughly 6 times the capacity of a smartphone battery and 3 times the size of a 7″ tablet’s. Physically, it’s around 9 x 9.5 x 2.5 cm and there’s bit of weight to it at 280g / 10 oz but it fits comfortably in the hand, especially with the soft curved edges of the iCarrier.

New Trent IMP120D

As the pictures show, it’s not unattractive for a battery pack and gets away from the standard rectangular brick. The black plastic enclosure has a blue central band with just four features – an on-off button, a power input socket and two USB ports. The on-off button lights up when charging  and a short press of the button briefly shows the iCarrier’s charge level using three blue LEDs for low, medium and high.

New Trent IMP120D - front

Two USB sockets obviously allow two devices to be charged at once. One socket is rated at 1 A and the other at 2.1 A, which practically means that you can charge a phone and a tablet at the same time. In the box along with the iCarrier, there’s an AC wall charger, a USB to microUSB charging cable, a charging cable for Samsung devices and a soft carry pouch. Contrary to the “i” moniker, the iCarrier will charge anything that will charge from USB, not just Apple devices.

Unlike some other devices, it’s possible to charge both the iCarrier at the same time as it charges other devices, which means that when travelling, only the iCarrier’s charger needed to get everything charged up overnight – the battery pack plus two other devices. The iCarrier does take a good few hours to get itself charged up, which given the larger than average battery isn’t to be unexpected. There are some other handy features too. For example, the iCarrier automatically shuts off once attached devices are fully charged.

In use, the iCarrier can be simply used as a backup battery pack to recharge phones or other devices when their internal batteries get low. More usefully, the iCarrier can be used to extend the life of portable equipment such as personal wireless routers. My MiFi can run for a couple of hours on its own battery, but connect it up to the iCarrier and I can get a whole day of use out of the hotspot without any trouble at all.

Overall, the iCarrier is a very handy gadget, essential for any heavy smartphone user or frequent traveller. It’s competitively priced at around $70 in the USA or £40 in the UK. Recommended.

Disclosure – The iCarrier IMP120D was a personal purchase.

Making Solar Pay

Posted by tomwiles at 8:54 PM on May 8, 2013

I have always been fascinated by the idea of generating my own electric power. Back in late 1998 I installed a solar power system that has sixteen 75 watt solar panels, along with a 4,000 watt power inverter/charger and a bank of expensive deep-cycle batteries.  Mention solar power, and most people think that all of these elements are necessary, including the expensive bank of batteries.

It turns out there is a much better way to think of home solar energy – use solar energy equipment strictly to push power back into the electric company utility grid. Batteries should never be considered to be part of a solar installation unless utility power just isn’t available, say in a remote location. Battery technology is an albatross when it comes to being able to store enough power to meet real-world needs.

If electric grid power is available, there are only two elements necessary – the arrays of solar panels, and what are called grid-tie inverters. In this battery-free scenario, the math of pushing power back to the utility to offset electrical use becomes much more interesting.

Power companies in the United States are required by law to “buy back” consumer-generated power. A grid-tie inverter takes the DC power being generated by the solar panels, inverts it into AC power, and then sends it back directly into the grid via a standard AC power plug plugged in to a regular 110 volt outlet. It is possible to have more than one grid-tie inverters, which also come in different sizes.

The relatively high-end inverter that I have is capable of producing 4,000 watts sustained output. So, if I wanted to push 4,000 watts back into the electric company utility grid, I would need at least two more arrays of solar panels feeding DC current into the inverter.

In my case, the batteries died within about the first three to four years. I simply turned the equipment off and my youngest brother sold the battery carcasses to a battery recycler. The equipment sat dormant until yesterday. A friend that does solar as a hobby helped me check the inverter and get it up and running again. I contacted my electric company and they sent a man out this afternoon to look over and approve my system, an absolutely necessary step. So the net effect is that now whenever there is daylight, the inverter is pushing power back into the grid. Obviously the maximum amount of power is generated when the solar panels are in direct sunlight.

The electric company performed a test of the inverter to make sure that if there is a grid power failure that the inverter automatically cuts off its own output. This is quite critical to the power company, because they want to be absolutely certain that in case of a grid power failure, no user-generated AC current is being fed back into the downed power lines.

I was able to verify that my inverter was pushing power back into the grid by turning off all internal breakers in my house so that no power was being used. At that point I looked at the power meter out on the utility pole and it was actually running backwards! Of course, in normal operation with different things consuming electricity in the house it is unlikely it will run backwards much, but it will be slowed somewhat.

My local electric company is a rural electric cooperative and they actually encourage customers to set up these types of “selling” consumer-generating power systems. It helps them reduce peak demand, thus reducing the need for more electrical generating capacity on the utility’s side. Solar panels are generating electricity at peak capacity when peak demand is likely to occur when air conditioning demands are at their highest.

Can a system like this ever pay for itself? It depends on the initial cost of the equipment, installation expenses, and how long of a payback period you are able to live with. If you can do most of the installation work yourself, then obviously the math works better. Eliminating the batteries really helps the cost come down.

An HQRP 1,000 watt grid-tie inverter sells for $287.95 on Amazon.Com. Aleko brand 75-watt solar panels sell for  $149 dollars each. Sixteen of these solar panels multiplies out to $2,384 dollars. With brackets, wiring and installation let’s estimate a total package price of $4,000, which may or may not be wildly off one way or the other. The 1,000 watt electrical output of the inverter would have to offset $4,000 dollars worth of electricity over a period of years before it would pay for itself, which is likely a long period of years. If the price of the equipment and installation can be brought down, then the payback period shortens.

My electric company will only allow this type of setup to function as an offset. So, let’s say that someone was putting more power back into the grid than they were actually consuming. My power company will never issue a check for the power, so it’s really just an offset for how much I consume. With enough equipment feeding power back into the grid, it would be possible to bring electrical grid usage down to zero.

Many local and state governments offer tax rebates for new solar equipment installations, which could also help mitigate the cost.

The beauty of a battery-free grid-tie solar user-generated power system feeding into the electrical grid is that once it is initially set up, everything happens automatically. Since I already have the equipment and it is long since paid for, I might as well be utilizing it to offset a portion of my power usage.

More Juice for your Apple iPhone

Posted by Andrew at 8:58 AM on January 4, 2013

All smartphones drain batteries like electricity is going out of fashion but many external battery are bulky, fiddly or both. Gosh!‘s new Parallel battery for the iPhone 5 might be the first that’s both sleek and convenient.

The Parallel comes in two parts, the battery pack itself, and a matching iPhone case that makes connecting the phone to the battery an absolute doddle. The iPhone 5 can stay in the case when you don’t need the extra power, but as soon as the main phone battery starts to fall, whack in the extra battery and it’s good to go. The additional 2,500 mAh is a huge increase over the iPhone 5′s standard 1,440 mAh.

The Parallel battery has smooth lines that fit the iPhone 5′s taller size and the case comes in a choice of 5 colours too.

Gosh! Parallel iPhone 5 case and battery

The Parallel is on show at CES, North Hall, iLounge Pavilion, Booth 6723.

 

Power Sockets with USB Charging

Posted by Andrew at 11:36 AM on June 18, 2012

Last week I was at a trade show for electrical wholesalers and I came across these single and double power sockets with a USB charging point built-in.

Power Sockets with USB

As soon as I saw them, I thought, “Those would be handy…” and then I saw the price…£62.74 for the single and £76.60 for the double socket and they’re trade prices too (ex VAT). In US money that’s $99 and $120 respectively. As Todd would say, “Are these guys smoking crack!?” Who in their right mind would pay that kind of money for a built-in USB socket and a single USB socket at that? I can only hope that it’s a pricing error or a multi-pack.

With a bit of searching, I subsequently found another company that charges a far more reasonable £15 for a single socket and there are doubles going on ebay for £30 which is still pricey enough.

From the specs, it would appear that 1A is the rated current which will be fine for most phones and mp3 players, but tablets will take their time to charge.

For those who despise wall warts and power bricks, it’s a neat way to go, but make sure you aren’t paying over the odds.
