ISDT continues their line of affordable dual-channel chargers with the K series, which accepts AC or DC input - with a unique connection design to ensure that you can't accidentally connect both inputs at the same time.

The K4 offers 400W of charge power when running on AC power, or up to 600W per channel with a DC power source. Charge at up to 20A per channel, or put the two channels in parallel to increase the output.

The latest version of the scOS offers handy features like an adjustable DC output mode, enabling you to control the output voltage and current up to 150W. There's also a battery destroy feature for safe discharging and disposal of old packs, and even dark mode for the display!
