SWPKPOWER SW-B32929 Dual USB External 15,600mAh Emergency Mobile Power Bank w/ Adapters - White

Pros: this unit is lightweight, portable and packs a lot of power. i use this to charge everything from an iphone to an ipad to a blackberry playbook. As for an ipad, i can usually charge it for over 12 hrs while still using it and it has power to spare, quite handy if you travel a lot and there is no power outlet nearby. the bonus adapter heads are handy, if you need them and match most of the common devices out there.

Cons: when it is totally drained, it will take about 24hrs straight to fully charge, but when compared to units with less power, this is a short time to wait for the convenience this provides. But beware, do not charge this unit using a notebook or a laptop computer because they do not have enough current coming from them. Instead, charge this unit directly using an AC source or other reliable power source. I have yet to try and charge this from my car’s inverter unit so do so at your own risk. Also, unless you are a long distance truck driver, charging it for a few hrs using this method might not be too beneficial to you or too good for this device.

Other: i have told all my friends and business partners to get this unit. i highly recommend it. i wanted to put this unit through a few charge and discharge sessions before writing this summary. in fact, after i post this, i am ordering another one from dx. this relatively little unit packs a great punch and is excellent value for the money. You must consider this - a 6,600 mAh unit at future shop, best buy or the source (if they have one in stock that is) goes for over $99 so this one is a steal. if you buy this unit in bulk (3 or more at the same time), you get to save even more.

Pros: Size is just right. Weighs a bit more than expected but clearly packs a lot of juice. Charges two iphones (4s & 5) at the same time. Packaging is good. Nice big box and all the adapters are neatly packed.

Cons: No iphone 5 adapter. Orderd an extra cable here on DX.

Other: Going to use the product mostly for festivals and while travelling. Product seems just perfect for it.
