There are roughly a million and one rechargeable battery packs for smartphones (microUSB) these days. So what companies have started to do is become creative with how they design their battery chargers, in an attempt to capture the imagination and needs of the market. See all tech accessories reviews.
EnerGenie is one of these companies that has its own unique take on the rechargeable portable batteries. What EnerGenie has to offer is a battery pack that can be stuck, unstuck and restuck to your smartphone while charging. Take a look at Go Baby Mobile Power Pack review too.
Confused? Don't be, it's simple. All the clever chaps at EnerGenie have done, is design a battery pack that can be stuck to your smartphone when you are giving the battery a bit of a boost and then unstuck when you are finished charging. The mind-blowing thing (for me) is that you can restick the device as many times as you want thanks to the amazing glue/gel stuff that has been used.
The ChargeGenie is actually pretty slim compared to some other battery packs we've seen, but when you attach it to your (probably) sleek smartphone, any panache that your device once had will disappear instantly as you phone doubles in size. But in my opinion having a battery pack physically attached to a device is a much better way to charge your phone when you're on the go, than having a bit floppy wire getting in the way…as well as a bulky battery pack.
There are a couple of negatives that we noticed when using the ChargeGenie though. Firstly is that the battery pack gets really hot when charging is in full flow. So if you plan to carry this in your pocket while charging, make sure the ChargeGenie is facing out, not skinside.
The other negative point that is very noticeable is that the ChargeGenie will not give a 100% charge of your smartphone, more like a 60-70% from our tests (and depending on your phone's battery). This is a bit of a balancing act though, because in order to compete with some of it's battery pack rivals in terms of 'juice' it would have to be a lot bigger, which sort of ruins its portability factor. So this is both bad and good….60%-70% isn't that bad i suppose.
