Battery backup

[TimWaters]

Am looking for advice on the best type of battery backup for the iPhone 4S..?

Excellent online prices on these from retailers. I have an older 7000 mah version and it has 1A and 2A outs to charge iPhone or iPad. Excellent quality, quick to recharge the external battery. Way better value than those sold in the electronics stores.
