Lanyos Ultra-Thin Android Power Bank Built in Micro USB Cable Wallet Size 1500 mAh External Battery Charger

I'm giving this a 5 star rating because it met expectations, even exceeded them slightly. It's important to know what you're buying. This will NOT fully charge your phone. It's purpose is meant to be an easily portable emergency charger for when you need your phone to last for the day/night.Being a guy, I wanted an emergency charger that I can carry around in my wallet, because I don't usually carry a bag or backpack when I go places.This charger is super thin, the slimmest that I could find anywhere. It easily slides into my wallet which means that I can always carry around a charger with me in case my phone is going to die. The charger is loosely the size of a credit card in length and width. In terms of thickness, it's literally about as thick as half of a dime. This thing is very, very slim.The best part is that the charger comes with a built in lightning cable, so this only works for iPhones. I like this feature because it means that I don't need to carry around a cable in my pockets. It's all compact and ready to go. In my testing, this charged my iPhone 6 plus anywhere from 30% to about 38% at the most. I didn't test it on smaller phones but I'm assuming it would charge an iPhone 5 over 50%.If you are looking for a charger that you can slip into a wallet or into your pocket, this is the one for you. It's compact, it works well and it's the easiest way to carry around some extra battery life with you in case of emergencies. If you want a bigger battery that works on multiple devices, then I would recommend something else. But as a portable, emergency charger for iPhones, this one is perfect.

This was exactly what I was looking for. I have multiple battery banks but they are somewhat heavy and very bulky especially if you carry in a pocket. This charger is very small (about the size of a credit card) and absolutely disappears in your pocket. I have an iPhone 6s so the battery doesn’t last more than a few hours now. From 5-10%, this charger will get it up to 85-90%

This didn't work. The head was really flimsy. I tried to contact the seller a few times, but I didn't get a response. Not sure if there was a technical communication issue? Really disappointing.

Nice charger, perfect for all lighting connector products not just iPhones. Just wish the charger had a longer battery life

This is the most convenient buy I've made. it's great to just have in my purse and not have it take up a ton of room.

Battery life almost nonexistent. I don’t see it as an emergency backup as it really isn’t so portable as to not be cumbersome in some way. Do yourself a favor and buy a more significant backup battery.

Looked really great. Seemed well made and it was very slim. However, the lightning connector broke off and was stuck in my iPhone on the second use.... so really disappointing. I wasn’t mistreating it; it literally never left my house, and I wasn’t doing anything odd with the plug or trying to force it in any way. The plug just fell apart.

I got as expected, thanks AMAZON.
