The market is full of rechargeable batteries. No wonder, because if you run out of juice, you can save the trip to the supermarket and refuel the remote control, radio, etc. straight away.
AA rechargeable batteries as so-called “secondary batteries” can be recharged immediately after use. However, many AA rechargeable batteries require special chargers – impractical especially when you are out and about when there is no socket within reach. Modern AA batteries with a USB-C socket are a good solution. These can be easily charged at home using any smartphone power supply unit, or on the go together with the smartphone using the power bank.
In the test center we tested rechargeable batteries with USB-C in the standard size AA. The test result, in particular the test winner, is summarized briefly and concisely below.
