Mini Step Down Moudle Converter With TFT Color Screen Display 0.6-25.6V Adjustable 18650 Battey Buck-Boost Power Supply

Features

1. High-definition TFT color screen displays voltage and current in real time, making parameters easy to read and enabling more precise and efficient debugging
2. Freely switch between output voltages: direct output from 18650 batteries or output after buck-boost conversion
3. Wide-range buck-boost design (0.6V–25.6V continuously adjustable), suitable for testing various electronic modules
4. Compact palm-sized body; lightweight and portable—the perfect companion for on-the-go development
5. Features low-voltage protection; protection activates when battery voltage drops below 3.4V

Parameter Input Voltage Range: 3.3–4.2V Power Source: 18650 flat-top batteries (not compatible with pointed-top batteries) Output Voltage: 0.6–25.6V Adjustable Output Power: 5W Overcurrent Setting: 0–1250mA (0 = no output; adjustment resolution: 50mA) Overcurrent Response Time: 1ms Overload protection response time: 1 ms (fixed 5W protection, non-adjustable; reset time fixed at 2 seconds) Reset time setting: 0–9 seconds (0 means no shutdown) Average operating current: 30 mA–60 mA (no-load operating current) Display: 0.96-inch TFT LCD display (wide viewing angle)

Product Description The Mini Portable Power Supply is a 18650 battery-powered test power supply with an output power of 5W and a continuously adjustable output voltage of 0.6–26V ±10%. It displays parameters such as battery voltage, output voltage, output current, and output power in real time; It features overcurrent shutdown protection with an adjustable protection current of 0–1250 mA (0 mA means no output), as well as a resetting time setting of 0–9 seconds (0 seconds means no protection; this function carries a risk of damage, so please use with caution); it comes with an adjustable output port (Type-C) and an external current measurement port (XH2.542P); Note: This device supports low-voltage protection for the battery. Protection is activated when the battery voltage drops below 3.4V, at which point there is no output and the voltage cannot be adjusted. The protection state is exited and output is reactivated only when the battery voltage exceeds 3.6V. If both the protection current and the reset time are set to 0, the protection current setting takes precedence (i.e., no output);

Usage Instructions

1. Insert a charged 18650 flat-top battery into the battery compartment
2. Plug the included interface cable into the corresponding port
3. Turn on the main power switch
4. Set the overcurrent threshold and reset time
5. Switch between battery or buck/boost output 6. You can now power or measure the load
