Great for a go bag. Charges a battery and turns your flashlight into a phone power bank.
Ordered two of these little chargers and oddly enough, the day they arrived a car hit a power pole right by our house and knocked our our power for most of the night. My wife and I used some previously charged 18650 batteries with these chargers to recharge our iPhones that night. One 18650 hooked to this little charger brought my iPhone from 20% to fully charged in about 35 minutes. Very impressive on the speed to recharge my iPhone. The next day, when power finally got restored, I just plugged the charger into a usb outlet and recharged the 18650 I had used the night before to charge my iPhone. Very impressed with these and glad I have them. Worked great when needed and easy to store and carry in my backpack for use whenever. Great little item
I have an obscene amount of gadgets that require rechargable L-Ion Batts. It's not always possible to carry a bunch of spare, fully charged, Batts. with me and some things don't have a direct or easy way to charge them. I used to carry a small 2 cell charger with me but it couldn't handle being packed in a bag and also the contacts and springs failed quickly.
This little Smart Charger is going to be great to have with me at all times. I've already run it against my larger Nitecore charger and it charges a "dead" Batt. to full in just about the same time.
I just wish it had a slight longer USB lead.. something 8" or so would be helpful when using a wall outlet or to be able to position the battery up in a way so it's not dangling. But overall it's a solid product!
