4 Pack 3.7 V 18650 Rechargeable Battery Flat top with Charger, 18650 Lithium-ion Rechargeable Battery Set

Great purchase. Quality batteries that charged in the prescribed time. A good package and well priced.

I needed this specific type of rechargeable battery (just the one) to power a new UV flashlight, but did not have the necessary charger so I purchased this as a set because, a) for the battery (I now have three as spares), and b) for the charger. The price for the set seems fair and the charger (thus far) works really well. I am particularly grateful for the graphic display that show the status of how/when your battery is charged. You can charge two batteries at once or just the one. As for the batteries each of the four seemed to have a small amount of charge out of the box, enough for me to test if my flashlight, worked! I would though, highly recommend fully charging each battery before its first use. As I said thus far I am very happy with this purchase.

It charges the batteries, does everything i expected and hoped it would do

I dont know about the batteries as i havent used them yet and they dont work for blink solar camera, I can use the charger to recharge the existing ones when there is not enough sun and that's great.

The charger is great, I really like the switch to usb-C power input, it feels much more robust. However, the batteries don't put out the level of power they should, I'm having to up the wattage on my mod by 25% to match my other batteries output. Very disappointed.

Item as described. Batteries when they come require full charge

Work as described

The product was very good and it is very easy to use good value for the price Very happy with the product many thanks
