Romoss Polymos Air 10000mAh Synchronous Charging Power Bank (Dual Output 5V 1A + 5V 2.1A)

A superior Li-Polymer battery, offering Synchronous Charging and greater efficiency when compared to Lithium-ion power banks! Don't you hate running out of power on your smartphone, camera or iPod when you're out and about? It's a thing of the past now, thanks to these nifty little power banks. They're cute and portable and come with the ability to charge most tablets, smartphones and other mobile media players while on the go. Excellent! What I like best is that this mobile battery bank doesn't change the way you use your mobile. It's not a bulky case or car-dependent accessory - you can plug into this battery just like you do at home when you plug into your wall. It stores 10,000mAh of power, which is a full charge for most current mobiles, and you can use it in the car, in the caravan, on holiday, at the office or during power outages. Make sure you're prepared for anything with this super-compact must-have accessory. The included Micro-B USB cable can be used to charge the power bank, or charge a Micro USB supporting device. Plus you can use your own USB charging cables to expand into a wider range of charging possibilities. Dual output sockets - 1Amp and 2.1Amp for phone and tablets including iPad, with Fitcharge device detection for rapid charging. How much charge is needed for my device? Our battery banks and the batteries in your mobile devices are rated on the power delivered over a discharge interval. Confused? Not to worry! The bottom lines is that power is fairly inefficient when being exchanged this way, so a general rule is that you'll need three to four times the mAh power transfer rating, when compared to the size of the battery you want to charge up.
