USB Dummy Load Module 300mA Adjustable Virtual Load for Power Bank Anti-Shut Off, Keep Charging for Smart Watches, Earphones, Low Power Devices

Conoce más detalles

Prevent Power Bank Shut-Off: This USB load resistor acts as a constant "virtual device." It tricks your power bank into staying on by simulating a connected device, preventing auto-shutdown with low-power gadgets like smartwatches, Bluetooth headphones, or trackers. Adjustable Current Load (25mA-300mA): Features 4 selectable current modes (25mA, 50mA, 75mA, 150mA). Use the jumper caps to combine any combination of these loads to find the exact minimum current required to keep your specific power bank active (e.g., 50mA + 25mA = 75mA). Simple Plug & Play Setup: Easy to use: just plug the module into your power bank's USB-A port. If the bank still shuts down, simply add another jumper cap to increase the load current until it remains on. No software or complex configuration needed. USB-A Passthrough Design: Standard USB-A male input and female output port. Please note: This is a power-only module with a built-in resistor; it does NOT support data transfer. The compact size (50x23mm) and lightweight (9g) design make it highly portable. Universal Compatibility & Protection: Safely maintains a trickle charge for all your USB-charged, low-power consumption devices. An essential tool for anyone who uses power banks to charge small electronics that enter sleep mode or have very low charging current requirements.
