This 4-CH Charger is designed for the NANO series, as it is very compact and lightweight. Features simultaneous charging of all channels. The charging output is 1 Amp per channel.
You can also use it with normal batteries, please be aware that you can only put two normal V-Mount batteries onto the charger, as the space is too short for two on each side.
If you only put one battery on each side, the charger charges those with 2 Amps. Four batteries are charged with 1 Amp per channel.
