KKnoon 150W 20A Adjustable Electronic Load Tester — 2.4" TFT Display, CC/CV/CP/CR Battery Discharge

The KKnoon 150W/20A adjustable electronic load is a benchtop DC load tester that lets you measure, discharge and log voltage, current, power and capacity with selectable CC/CV/CP/CR modes and a 2.4" color display.

If you work with power supplies, lithium batteries, adapters or DC sources, this compact electronic load provides accurate discharge testing and protection settings in a handheld footprint. It accepts 0–150 VDC input and 0–20 A load current, records up to 999.999 Wh and 999.999 Ah, and offers adjustable protections and timing for repeatable capacity tests and troubleshooting.

How does the KKnoon electronic load help me test battery capacity?

The device can discharge a battery under controlled conditions while recording energy and amp-hour totals, so you get reliable capacity numbers. You choose a discharge mode and set cut-off voltage and time limits, then the load logs cumulative results.

• Capacity range up to 999.999 Ah and energy up to 999.999 Wh
• Selectable CC/CV/CP/CR modes for realistic discharge profiles
• Programmable stop voltage and time-limit discharge up to 99:59:00
• Four-wire measurement (A+ V+ V- A-) for accurate readings

Which protections and safety features are available?

Multiple protections prevent damage to the unit or the device under test: overvoltage, overcurrent and over-power thresholds are all configurable. The built-in alloy heat sink and automatic cooling engage when internal temperature or current rise, helping prolong reliable operation.

• Overvoltage protection up to 150 V and overcurrent up to 20 A
• Over-power protection up to 150 W (reduced above 120 V)
• Automatic cooling when temperature ≥40°C or current >3 A
• Optional external NTC temperature sensor support (0–100°C)

What display, controls and measurement precision can I expect?

The 2.4-inch TFT color screen shows voltage, current, power, accumulated capacity, internal resistance, mode and protection status for quick diagnosis. The unit supports zeroing and open-circuit calibration for voltage and current, and brightness and sleep settings to suit bench environments.

• 2.4" color TFT with Chinese/English UI switching
• Voltage range 0–150 VDC and current 0–20 A; power 0–150 W
• Voltage/current nulling, calibration and total-data reset functions
• Screen brightness and hibernation standby options

Who is this for: engineers, technicians, hobbyists and lab users who need a portable, accurate DC electronic load for battery capacity verification, adapter and power supply testing, or component validation. It suits bench and field use where controlled discharge profiles, clear readouts and configurable protections are needed. Measuring up to 150 W in a compact 165×95×80 mm housing, the KKnoon load balances capability and portability for everyday power testing tasks.
