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.

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.

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.

Boost Smartphone Battery Life

Mugen Power Batteries LogoToday’s smartphones are energy-sucking devices that can rarely go for a day or two without charging. I fondly remember my Nokia 6210 that could go a business week without needing a charge, but enough of the reminiscing.

If you do have a thirsty smartphone (or you get one for Christmas) and you find that the battery lets you down, you might be interested in Mugen Power Batteries, suppliers of replacement batteries for smartphones and other devices. Typically, a Mugen battery will offer an extra 10%-25% over the OEM battery of the same size. Take the battery for the HTC Wildfire S – the OEM is 1250 mAh but the Mugen version is 1500 mAh, giving an extra 22% more juice.

If you really need much more power, Mugen also sells batteries so big that you need a new back cover to fit it in. For the Samsung Galaxy S II, Mugen offers a 3200 mAh battery which nearly doubles the energy of the stock battery (1650 mAh), but the battery size increases too and a new back cover is needed. If you value talk time over aesthetics, it’s the only way to go.

Even Apple products are catered for, though as the iPhones et al don’t have user-replaceable batteries, the additional power has to come from an external unit.

Mugen are fairly well-known if you follow any of the main smartphone forums, and there are other vendors out there, but they seem to have the widest range with a good reputation, so if you need more power for your smartphone, check them out.
