All of our latest gadgets today need some sort of power to operate and that means, inevitably, that they will run out of power sooner or later.  In the case of mobile devices such as tablets, phones and laptops that time period is, unfortunately, sooner.  So a backup battery, charger or power device is a must have addition in today’s tech savvy world. 

It’s a good thing then those clever folks over a BatteryBox are trying to make life a little easier then isn’t it?  BatteryBox is the hottest gadget to offer additional power on demand. The device is notable for two reasons: the sheer amount of power it offers in its small packaging and how long the BatteryBox will last before the batteries inside begin to degrade.
First off, the power capabilities: Maker Gbatteries Systems Inc. claims the 50Whr BatteryBox is competent enough to power a MacBook Air for 12 hours, a MacBook Pro for 6 hours, or can recharge 8 iPhones before it needs recharging again. The BatteryBox device itself takes 9 hours to reach full capacity using a micro USB charger. You can halve those times by switching to a 2A power supply, if you desire.
The cost is $139.  I agree it is a lot to spend on a backup battery, but the reason for the price is quite relevant , Gbatteries have created and developed,BatteryOS; a smart battery management system.  Gbatteries has developed BatteryOS to control the rechargeable lithium-ion batteries inside the BatteryBox for a more effiecient life cycle.
This system allows for 4x higher cycle life and that means 3,000 charge/discharge cycles will retain a 96 percent capacity. Users can typically expect to get 5 years of use without any battery degradation. BatteryOS can dynamically manage the batteries and the BatteryOS is always managing the energy inside a battery to ensure that it doesn’t degrade like an unmanaged battery will do.
The BatteryBox uses a MagSafe2 adapter to power MacBooks.  When I say power it, I mean just that as the BatteryBox doesn’t charge the battery, it just provides power. The BateryBox also has an adapter which allows it to be unlocked so it can be used by any device that allows USB charging. The device measures 0.98 x 2.63 x 3.55-inches and weighs 250 grams. Inside is a 50Whr, 12,000mAh battery pack.  The price is $139 with the first shipments occurring sometime in the 3^rd quarter.
