These batteries are always great. It's all I've ever used. Fast shipping as well.

4th June 2019 - William Kelshaw

Four brand new Samsung batteries, tried charging in two different chargers (one brand new). All show as completely charged within 30 minutes, and last no more than ten minutes in device. Fairly new vaper here...can anyone help? I feel completely uncomfortable fiddling with the batteries, as I've read on various message boards.

Great batteries so far. Long life under semi-heavy/moderate use. Charge times via the mod are a little long using USB or AC but not too bad.

5th May 2019 - Russell Devine

This battery has lasted me days!! Don’t forget to buy an external charger (like me lol). They don’t take long to charge up either. Great product.

26th March 2019 - Kelsea Webb

Working fine for now

23rd December 2018 - Tariq Bennani

13th July 2018 - Jonathan Mandell

6th April 2018 - Matilde Tejada

No problems with this.

23rd March 2018 - April Van Hoorelbeke

Takes a full and fast charge

16th March 2018 - Jim Stewart

They have never gave me any problems and the price is way cheaper than buying them in a store. Good quality for a low price. Would definitely recommend if you go through batteries a lot.

7th February 2018 - Hannah Pate

I use these batteries in my Alien 220 and my T-Priv 220 Mods, and they work wonderfully. At 50 to 75 watts, I can get a full day's use out of them easy. I have 4 of these batteries, I have one pair in the mod, and one pair in the charger. I find myself swapping them out every other day or so. Very good batteries for sub ohm vapers!

19th January 2018 - Andrew Castillo

it fits perfect on my vape

24th October 2017 - Jenny Flor

Hold a charge and haven't blown up yet.

6th July 2017 - Nicolis D Cothran

It's a rechargeable battery and you need them to use your vape. Samsung always makes really good products, so I have nothing bad to say about this battery.
