Verbatim Dual USB Power Pack Review

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

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.


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.

Zens Qi Wireless Charger

Although I was disappointed by the Nokia DT-900, I wasn’t ready to give up on wireless charging nirvana for my Nexus 4. With a bit of searching and review-reading, I plumped for a Zens Universal Qi Single Wireless Charging Plate which garners 4.5 stars on Amazon. Although unknown to me, Zens is a young Dutch company specialising in wireless charging products, and from first appearances, it looks like they’re doing a good job.

The Zens charging plate comes in a well-presented package but is surprisingly small. It’s bigger than the DT-900 but it’s still not large and I imagine that most large screen smartphones will overhang on one side or another. However, the extra size and the rubber covering mean that most smartphones will sit comfortably on the pad. As with the DT-900, it has a DC power supply – no USB charging here, either.

Nexus 4 on Zens Charger

In use, the Zens charging plate is far better with the Nexus 4 than the DT-900. In most instances, simply placing the the Nexus onto the pad started charging and usually, I’d get a high rate of charge without any precise positioning. With a bit of practice, I was able to get a sweetspot that worked every time and an LED on the right side of the plate turns green when the pad starts charging.

The screenshot below shows the charging rate when everything is perfectly aligned and honestly, it’s not far off the rate when the Nexus is plugged in.

Zens Charge Rate

The plate also has a feature that when the phone is fully charged, the charging turns off until the the battery levels falls to about 93%. Here’s what it looks like in Battery+.

Zens Wireless Charger - Full charge

In my opinion, the Zens charging plate knocks the DT-900 into a cocked hat, especially if you have a Nexus 4. Both are priced a little under £45 here in the UK, though the Zens charger seems quite pricey in the US at $100 (Amazon). Update – have since discovered the Zens charger on other websites for a far more reasonable $50. Recommended for all UK Nexus 4 owners.

LG Nexus 4 and Nokia DT-900 Wireless Charging

Being an ex-Palm afficionado, I’m a massive fan of wireless charging. The convenience of simply placing a Pre onto a Touchstone to charge is unparalleled and I still use wireless charging with my Cyanogen-modded Touchpad.

Today, the Pre series is history thanks to HP, but wireless charging is still around with Samsung, LG and Nokia all supporting the Qi standard. My current phone is a Nexus 4 but the official orb charger is a small fortune here in the UK, so it was with interest that I saw that the prices of the Nokia DT-900 charging pad were gradually falling. Last week, I finally succumbed and bought one.


First impressions are mixed. The DT-900 seems reasonably well-made with a single white LED at the front to indicate the status of the charging. Unfortunately, the DT-900 comes with a somewhat chunky power supply which connects via a cable with DC jacks at each end. It would be far more sensible and useful if it used micro-USB connectors. And who thought that a white PSU with a black pad was good idea?

DT-300 Charger

But on to the wireless charging….

Reports from elsewhere on the web suggest that the Nexus 4 and the DT-900 should work together but my experience was somewhat mixed. The main issue is that positioning the Nexus on the plate is crucial for the charging to ‘lock on’. Incorrect alignment causes the plate’s LED to flash and the phone will continually stop and start charging.

DT-300 Plus Nexus 4

I tried a wide variety of positions, but even when I managed to get everything lined up, charging was poor, as you can see from the attached screenshots from Battery+.

Screenshot_2013-07-21-21-01-25 Screenshot_2013-07-21-21-01-55

Best results were from putting the Nexus 4 on the pad such that about a quarter to a half inch of the pad is visible at the bottom, but even then the battery charge level seemed to hit a plateau at around 80%

Maxed Out

Overall, it was disappointing and the DT-900 will going on ebay very shortly. One might have though that in the four years since the Palm Pre came out that wireless charging would have been perfected. Regrettably, if the DT-900 is anything to go by, it has a long way to go to even match what Palm offered. YMMV.

New Trent Easypak NT70T External Battery Review

New Trent LogoIf you like your gadgets black and shiny, then the New Trent Easypak NT70T is going to be the external battery pack of choice. With a polished black top surface and a matte back, it looks great but won’t slip out of your hand either. It’s perfect for travelling too, with built-in connectors, dual USB ports and a substantial 7000 mAh battery.


Physically, the Easypak is about 7cm x 12cm x 1.7cm, and is easily mistaken for a slightly fat smartphone. The shiny top surface has single button which when pressed either shows the current charge level of the pack or starts charging any attached devices. Four green LED lights across the top of the surface show the battery level, and they flash while charging. Personally, I would rather the LEDs were blue or white, but that’s just my taste.On one side there are two standard USB ports, but the cool trick is that on two other sides, built-in cables peel out for recharging the NT70T and charging a device via a micro-USB plug. This device charges only via USB which again keeps the weight down when travelling: simply plug the Easypak into your laptop and it charges. A USB extension cable is included in the box.

(Apologies for the less than perfect photo – the autofocus on my camera struggled with the reflections from the top surface.)


The two USB ports are rated differently, with one at 2.1A for tablets and the other 1A for smartphones. The micro-USB connector is also rated at 1A and while it might seem that three devices could be charged at once, in practice only two can be charged. In my testing, it seemed that the current draw was the limiting factor but I’m not 100% sure.

USB Ports

Unlike the New Trent iCarrier, the USB ports can’t be used while the Easypak itself is charging, though the micro-USB plug can recharge a smartphone while the Easypak is charging. I note that in the device FAQ, New Trent suggest not to charge while charging, so perhaps best only used in an emergency.

Galaxy Nexus ChargingDevice charging rates are excellent. With both a Samsung Galaxy Nexus smartphone and a Motorola Xoom 2 tablet connected, the Easypak charged the phone from 18% to 75% in an hour and the tablet went from 27% to 50% in the same hour (as measured by Battery+). That’s no different from plugging either device into their manufacturer supplied chargers, so a good result there.

Overall, the Easypak is almost the perfact battery pack and I would choose it over the New Trent iCarrier, even though the iCarrier has a larger battery capacity and can charge while being charged. The neatness, the clean design, built-in cables and lower cost make the Easypak the overall better solution for me.

Available from the usual online retailers for around less than £30 or a little over $40.

Disclosure – the Easypak NT70T was supplied by New Trent for review.

New Trent iCarrier IMP120D External Battery Review

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.

Vivick’s Latest Gadgets

Vivick HeadphonesCanadian firm Vivick produce a wide range of gadgets, covering everything from iPhone cases, laptop accessories and AV gear. Andy and Scott look at three of the latest products.

On show from Vivick is anLED desk lamp speaker that can be driven via Bluetooth but wouldn’t look out of place on the set of a 70s sci-fi movie. Continuing the theme, they had a Bluetooth headset which looked a bit more up-to-date but I can’t comment on the sound quality. Finally, they showed off a combo-laptop / USB rechargeable battery which had some really good design ideas. It seems to be a brand new product as it doesn’t yet feature on their website, but if you are a battery hogging traveller, keep an eye out for it.

SpareOne Emergency Mobile Phone at CES 2013

SpareOne Emergency PhoneModern smartphones are expensive, relatively fragile and battery-hungry. Consequently, they’re pretty much useless in any tough emergency situation. Todd talks to Christian Scheder of SpareOne about their solution to the problem.

The SpareOne emergency phone is a mobile phone that runs off a standard AA battery rather than a rechargeable one more usually found in a mobile phone. While this gives 10 hours of use from a single battery, the benefit in an emergency is that the battery can simply be swapped for another. Further, Energizer Ultimate Lithium AA batteries have a storage life of 15 years so this phone can be stored with batteries for up to 15 years, ready to go. The SpareOne is supplied in a waterproof bag that further protects the phone during storage and any wet emergencies.

The phone takes standard GSM SIMs for ordinary calls but the SpareOne can also call the emergency services even without a SIM card. If you are interested, the SpareOne is available now for $99 from the website.
