I'm looking at purchasing an external rechargable battery pack to charge portable devices - ie mobile phones and an iPad. 'Twas looking originally at one of those tiny units (eg 2,600 mAh) on a one-day deal website just for the mobiles, but after reading reviews of similar units on Amazon thought they were potentially a waste of money.
So... can anyone offer some advice as to what to look for, including capacity and output (say enough to charge both a standard Android handset and an iPad Air on a single charge), and potential recommended (but affordable) models?
I've seen a few on DX.com and eBay of 8,000 mAh+, which claim to be good for enough charges of an iPad, and offer two charging ports (one at 1A and the second at 2.1A). Given the higher needs of an iPad, I take it I should be looking for one like this?
Further, does price/quality make a significant difference or add a big risk to the equation? There are apparently bagain-priced units such as this one - should I be weary? (While I accept there's a risk the capacity of such a cheap unit is not as advertised, even if less wouldn't this do the job adequately, or are there problems to watch out for?).
Finally, if anyone has purchased such units overseas, have there been any issues with shipping (given these matters)?
