Blackcell BU1 USB Charger

The BU1’s integrated USB output function allows the charger to be used as an external charging station. The BU1’s automatic detection system can detect Li-ion, Ni-MH and Ni-Cd batteries whilst also selecting the charging mode for each independent battery. The BU1’s three LEDs clearly display the current charging operations.

USB Output

• USB output voltage: 4.90-5.30V
• Output current: 1000 mA
• Floating current <1mA
• When the load current is at 1000mA, the USB output voltage is:between 4.75-5.25V
• Cutoff output voltage:3.0±0.1V

Button and LED

• Keep the button pressed for 2 seconds to switch the charging current from 1000mA to 2000mA.
• All LEDs will light up when the charger connected to a 5V power supply. If no Batteries are inserted, the LEDs will turn off.
• Batteries are automatically detected by type and will start charging once inserted. The LEDs will flash, showing the battery‘s current power.
• Without the power cable connected, insert a battery to check the remaining charge. (LED will turn off within 5 seconds, press button once to display once more)
• USB output: The power indicator light will stay lit for 10 seconds after a battery is connected.
