  1. "Great Christmas gift 5 Star Review

    Posted by on 27th Dec 2018

    Charger/power source is a Christmas gift. Nice gift. Believe it will work well for both charging and power source.

  2. Handy device 5 Star Review

    Posted by on 23rd Oct 2018

    Besides charging the battery it becomes a handy power source on an as needed basis. Has a nice case as well. Quite lightweight too for those who count each gram in their rucksacks. Well done. Would I purchase one again? Already have.

  6. Vrey Good, but 4 Star Review

    Posted by on 5th Mar 2017

    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.

  7. Excellent! 5 Star Review

  9. Great Lamp... VERY POOR U1 Chargeing unit 3 Star Review

    Posted by on 11th Dec 2016

    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

  10. great charger 5 Star Review

    Easy to use. Charges quickly

  11. Works As Advertised 5 Star Review

    Posted by on 3rd Oct 2016

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

  12. Good charger. 4 Star Review

    Posted by on 9th Sep 2016

    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.

  13. Very Nice & Handy!! 5 Star Review

    Posted by on 21st Aug 2016

    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
