Vrey Good, but

This is a great product. I have used it many times as a power bank to charge my cell phone. I do recommend it and would buy it again. However, when I try to charge NiMH AA batteries for my Thrunite head lamp (which i use every day), this charger alternates red light to green light. This is an indication that the battery is in the charger reversed, but actually it isnt. So i cannot charge my headlamp batteries with this, which is one of the reasons i purchased it. Still a good product and works very well as a power bank.

Great Lamp... VERY POOR U1 Chargeing unit

Great Lamp... The two U1 chargers I bought don't work worth a crap. Either the connector is too short or the insert on charger is too deep, cause it DOES NOT CHARGE unless you stand there & hold it

This is an effective compact charger that also works as a battery bank. I'm glad I purchased it. Worth every penny.

Good affordable charger. Charging AA/AAA batteries is very fast.
Functions as a battery bank also.
A samsung phone charged ok.
But it did not charge my Sony Z3 compact.
Perhaps Thrunite can post a compatible list of phones it will charge.
Very Nice & Handy!!

I purchased this charger and battery combo to compliment my TN12 flashlight. As someone who uses his flashlight on a daily basis , it is comforting to know I will never be left with a dead battery. Very high quality product that I recommend to all of my friends.

I purchased the i1 charger as an accessory to go with my thrunight tc 12 torch which recently from Amazon uk the tc 12 is a rechargeable torch but it is still very handy to have a spare battery to go with it & this small charger/powerbank is perfect for this purpose very pleased with it

I'm a policeman and I'm very happy that I can charge my battery in the comfort of my police cruiser, thanks to the USB adapter on the charger. Even charge my cellphone in an emergency. My TN12 2016 is working great with the Thrunite 18650,3400mah battery. It's give quite good running time. Thanks Thrunite for make my Night Shifts at the police department of Puerto Rico more secure. I trust you and I know that when my life is in danger I can depend on you. Thanks again.
