    Some use these as a 'just in case' tool when your device runs out, but I've found that this is really helpful to just give my devices that extra boost. Especially at night, where I don't have a plug near my night stand. I use this to charge my phone over night. The fast charge really does charge fast. I get a lot of charges out of this before it starts to get low. It does take a while to recharge, so don't be in a hurry and just plug in it somewhere when not using it.
