These are interesting rechargeable batteries that are recharged through a USB-C cable. They charge super fast and lasts a long time. I can confirm these batteries work perfectly on kid toys and recharge well.Very practical as you can charge on its on battery, you don't need a charger. Sturdy and durable material. Perfect for travelling.

My biggest issue with rechargeable batteries is the charger part. They’re always so expensive and they never seem to last and all the rest of it that goes with getting rechargeable things. When I saw how these charge and that they came with the 4 in 1 charging cable ,I think these are the greatest rechargeable batteries EVER. Fantastic! A+++

A great idea for our planet, recharging batteries is the way to go. I haven't noticed a difference in power between these and regular batteries and they charge fast. They do cost is a little bit more but you'll imagine how much you will save in the long run. I really enjoy being able to recharge these and not having buy new ones, every home should have them.
