In an increasingly mobile world, portable devices have been evolving in an extremely significant way, featuring more processing power and higher storage capacity than ever before.
Batteries in general though, have not kept up with these improvements. I mean, while improvements have been made in increasing battery life, today’s batteries still fail at sparking users’ attention – and we’re talking about very demanding users. A battery life of only one to two days always seems insufficient, especially when people are trying to get the most out of their devices and then the battery dies in less than a day.
With this in mind, the first powerbanks, that is, the first portable electrical energy storage devices, popped up in the market, providing us with a new way of charging our portable devices. They’re literally “power banks” which have become very useful for the aforementioned very demanding users whose batteries never last more than a day.
After several powerbank brands emerged in the market of mobile accessories, Asus didn’t want to fall behind and announced the Asus ZenPower 9600mAh this past February. We were first introduced to this beauty at the Mobile World Congress 2015 in Barcelona and no doubt people compared it to the Xiaomi Mi powerbank 10400mAh, given the similarities between both units. If you look closely at them, the truth is, they do look pretty identical, except for the different brand logos they bear on their casings.
The Asus ZenPower powerbank features a really interesting design, showing off curved shapes and distancing itself from the more traditional square looking powerbanks. It feels nice to the touch and also feels a bit slippery. The device has a micro USB port and a full-size USB port, so you can recharge the powerbank itself and other devices (5V/2.4A), respectively. It also features a power button that shows its current battery life, indicated by four LED indicators.
The device is 18mm thick, fitting comfortably in your jeans pockets. The main problem is that it weighs around 215 grams. Nevertheless, it’s deemed necessary as the powerbank is made up of three 3200 mAh batteries packed inside an 11 layers of protection.
What’s really important in these kinds of mobile accessories is their charging power. Asus really hit the bull’s-eye as its 9600mAh battery capacity can charge, for example, an LG G4 twice (which we’re currently testing), a Moto 360 at least once and still have some residual charge left. These results are super interesting, even more so if we take into account that the Asus 9600 was able to successfully charge the LG G4 almost as if it were connected to the original power transformer. This means that besides having good battery capacity, the Asus 9600 also has more than enough output current to quickly charge our portable devices, guaranteeing that in very few minutes we’ll be able to have enough battery life to make that urgent phone call.
