This 2-Bay USB-C Charger from Watson is a USB-C or AC powered unit designed to charge up to two Watson 9V Rechargeable NiMH Batteries at home, in the office, or on the road. The dual-slot design independently charges and distributes power based on battery type and quantity, which can be visually identified as fully charged via an LED indicator. To manage overheating and overcharging, the charger is equipped with built-in safety circuits to automatically cut power for safe and efficient use, while protection circuits prevent short circuits or reverse polarity.
