Micro Charger + Boost for USB Powerbank 5V, USB-C

Product detailed description

The mini charging module for lithium-ion batteries offers a complete solution for powering portable devices. The module enables safe battery charging via the USB-C port while providing a boosted 5V voltage for powering other circuits. Integrated overcharge and short-circuit protection functions ensure reliable and safe operation. However, always use a battery with integrated protection, like our battery from GeB

Specifications:

• Compact dimensions: The module is smaller than most similar products.
• Supply voltage: 4.5–5.5 V (USB-C)
• Battery support: Suitable for all types of 3.7V Li-Ion cells, including 18650 and Li-Pol (We recommend using one with integrated protection, BMS)
• Maximum charging current: up to 1.0 A
• Overcharge and discharge protection:
  • Disconnection during discharge: 2.9 V
  • Charging termination upon reaching 4.2 V
• Output voltage: 5 V (boost), when loaded at 1 A, the voltage drops according to the battery status to approximately 4.9–4.5 V
• Output current: approx. 450 mA, max. 1 A
• Standby Consumption: approx. 0.8 mA

LED indication:

• Green Flashing: Battery is charging
• Green Solid: Charged
• Blue: Output active (when drawing power)
• No Diode: Module in standby (no power draw)

Function:

• Automatic switching between charging mode and output
• Automatic termination of charging when the current drops below 100 mA
• Pre-charge with 200 mA current occurs at voltages below 2.9V
• Input/output via USB-C, soldering pins or connector – all are connected, so it doesn't matter which one you use
• Protection circuit: overvoltage, undervoltage, overload, short circuit

Package contents:

• 1× Micro charger + boost for USB Powerbank 5V, USB-C

Comment:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• The module does not have an official fast charging protocol, so it may be incompatible with some phones
