Mugenizer N11 Qi Charger with Battery Review

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.

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.

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.

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.

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.

Energizer announces the first inductive charger with QI technology

Energizer is releasing a new inductive charging system this October at Target stores and on Target.com. It’s officially called “Energizer Inductive Charger”

The new charging pad will charge any QI (Pronounced Chee) enabled device or a device with a QI accessory. Energizer will have the first two of these accessories available at the same time. They are starting with the iPhone 3G and 3GS sleeves and a BlackBerry® Curve™ replacement battery door. They say they will have more accessories available at a later date. Ultimately, doors and sleeves will not be required as manufacturers begin introducing new devices with the Qi standard built in.

Imagine sitting at your desk and just putting your smart phone on a nice looking pad and not having to plug it in to keep it charged. Or at the end of the day, just put your gadgets on the pad at the bedside and they will be all charged up in the morning.

In the past, these inductive chargers all had a different standard and had to speak the correct language to work. QI is an open source standard so any QI device and charger can work together. QI does require metal to metal contact to work. QI Logo

I’m looking forward to having a charger like this for my smartphone (Droid).
