Electronic Load Tester – Constant Current 5A 35W Adjustable, Battery Capacity Checker With Digital Display, Overvoltage Protection

About This Product

This constant current electronic load tester is a handy tool for checking battery capacity and testing power supplies.

It handles up to 5A and 35W, with adjustable current via a rotating encoder knob that lets you dial in 0.

01A precision—and you can lock it to prevent accidental changes.
Input voltage range is 5-30V DC with reverse polarity protection (won't burn out if you hook it up backwards).

The display shows voltage, current, and discharge data clearly.
It supports overvoltage, overcurrent, over-power, undervoltage, and overtemperature protection—all user-settable.

Also has data group memory so you can track capacity and runtime across multiple test cycles.

The intelligent temperature control fan kicks in as needed to keep things cool.

Great for testing batteries, chargers, or DC power supplies.

Compact and reliable for hobbyists and repair techs alike.
