    Good product ! I repurchased it for my vape. In case someone is wondering if this suits the vape mods RTA and RDTA tanks. Yes it does. Go for it. Safe and effective . Lovely ontime delivery and reliable service from Robu.

  6. Aiden (verified owner)

    The batteries are pretty good. Used them for my JBL Xtreme . The batteries in the JBL were very weak and bloated ( would give only 10 mins of power back up)

    I put these Samsung batteries in and it’s giving a good back up time . Still need to test them . So far so good . Quality batteries .

    Only delivery was an issue . FedEx delayed it


  7. Simon George (verified owner)

    Excellent. These can discharge at 20A as claimed. I could fly my 5 inch quadcopter with this. when in high discharge they do get warm around 40C.

    The best offer available on India for these battries. Due to lot of counterfeit 18650 in the market with no recognizable authenticity of the product it becomes quite difficult to get the original item. I have checked these for their high discharge rate and (20 Amps) and 2500mah capacity.. any one who wants a genuine product pl go for it.

    I loved it. The delivery was also very fast. Usually it takes 1-2weeks to get to my area.. But it took only 2 days.. Wow.. And the products are alse very mucj satisfying.


  17. Tim Muise (verified owner)

    I was very sceptical about the quality and authenticity of these batteries, due to their price. Amazon’s best price is more than 40% more. I was pleasantly surprised when I charged and used them. I’m not a battery expert, but they have held a charge in my vaporizer for more than two days now, with constant use. I don’t even know how can even sell this product for their price, it’s quite baffling. I will definitely recommend to all my geek friends.
