    Smallest flat charger I could find at this price range.  Note: it's 1 amp, so it will not charge as fast as your other chargers
  

*by U***R on Reviewed in the United States on September 5, 2016*

Charges my devices and fits (albeit somewhat uncomfortably) in my wallet.  I wouldn't actually want to keep it in there on a daily basis, but when I'm going for a pokemon go walk at a far away park, I pack this in my wallet in case a friend needs an emergency charge, or in case my external battery pack dies faster than I expected it to (since I also share my battery pack with anyone that joins my group that says they're low on power).Keep in mind that it only charges at 1 amp, meaning it will likely charge your phone half as quickly as your usual source of power.  Assume it will charge about as fast as your computer charges it through a USB port (you've probably noticed that when you plug your phone into a computer, it charges a lot more slowly than when you plug it into your wall outlet; this is because most modern wall adapters put out power at 2.1 amps).  It's also worth mentioning that it'll be like 3 times slower if you have one of those fancier "quick charge" or "super charge" technologies that some higher end phones use.  Basically, I'd expect an average phone to charge in about 4 hours using this charger as opposed to the usual 2 hours that most chargers take.So why am I giving it a 5/5 when it's got this glaring 'weakness'?  Because at this price point, you're very unlikely to find a 2.1 amp charger that has a flat design like this.  I bought this after looking at the specifications and seeing it say 1 amp output in the picture, so I got what I was expecting.  I'm putting this review out there so that the product doesn't unfairly get a review from someone saying "what the heck, this charges so much more slowly than my other charger, something is wrong with it, 1/5 stars".  Realistically, the only reason you'd want to buy this product is if you want something super portable that you can put in your wallet or in a place that is tight for space (maybe a glove compartment or in a shirt pocket?).  If you need a fast charger, then I'd say go for something bigger and maybe slightly more expensive.  In fact, I'd highly recommend one of those 4 (or more) slot USB chargers that put out 2 amps per slot if size is not an issue.  Or if size is somewhat of an issue, but you don't need it to be as small as this product, then perhaps get this little guy instead:  https://www.amazon.com/iClever-BoostCube-Technology-Blackberry-Bluetooth/dp/B00QTE09SY/  This one puts out a little over 2 amps per port, so you get the fast charging speed that you're used to (sometimes even faster than what you're used to, depending on how cheap your existing charger was!), while also being somewhat small.  But keep in mind you won't be able to put it in your wallet.
