Excellent and genuine Samsung 30Q's
March 1, 2019
I ordered 4 of these to build a portable charge pack for a heated jacket. I tested them in a LiitoKala Lii-500 4 Slots Smart Intelligent Battery Charger bought from Banggood.com. All four batteries tested at or above the 3000 mAh nominal rating. Some in the 3200 to 3400 range after cycling them a couple of times to condition them.

Beware of buying these from Chinese companies or on Amazon; many are counterfeit in that channel. It appears BatteryJunction carries the real goods at a good price point.

The best Yet for the Money
December 22, 2016
I purchased these, with the intention of building USB charging banks out of them. They seem to be really good batteries. I test all of my cells before I install them in a power bank and these are true to their rated capacity. Most were at 3,000 MAH or a little under or over that capacity. For the money I think that these are pretty good quality. I would recommend them, at least for a battery bank. Not sure if they would be good for a Vape product.
ProsCheap Price. Good power reserve. Not over rated.
ConsNone that come to mind.
