The Power Bank Module with Dual USB Output – 3.7V to 5V 2A with 18650 LiPo Charger is an integrated battery charging and DC-DC boost converter module designed for building DIY portable power banks and rechargeable 5V power supplies. The module combines lithium battery charging, battery protection, voltage boosting, USB output, and battery-level indication functions on a single compact PCB.

The module is designed to work with 3.7V nominal lithium-ion or lithium-polymer batteries, including 18650 cells. Its built-in boost converter steps the battery voltage up to a regulated 5V USB output, with common versions providing selectable or port-dependent 5V 1A and 5V 2A outputs through two USB-A ports. A Micro USB input is commonly provided for recharging the connected battery from a regulated 5V USB power source.

The board also includes a 4-level LED battery status indicator, automatic load detection, and intelligent automatic shutdown when no suitable load is detected. Common versions integrate protection functions such as overcharge, over-discharge, overcurrent, undervoltage, and output short-circuit protection.

Its all-in-one design makes it suitable for custom power banks, portable electronics, rechargeable robotics projects, emergency USB chargers, battery-powered Arduino projects, IoT devices, and other applications requiring a rechargeable 5V USB power source.

FAQ

1. What is the Dual USB Power Bank Module used for?

The module is used to build rechargeable portable power banks and battery-powered 5V USB supplies. It combines battery charging, voltage boosting, USB output, battery indication, and protection functions in a single module.

2. Can this module be used with a 3.7V 18650 battery?

Yes. The module is designed for 3.7V nominal lithium-ion batteries, including common 18650 cells. The battery voltage is boosted to a regulated 5V output for USB-powered devices.

3. Can both USB ports be used at the same time?

Yes, both USB ports can be used for powering compatible devices. However, the total practical output current depends on the exact module version, battery condition, battery current capability, wiring, and thermal conditions.

4. Does the module charge the connected 18650 battery?

Yes. A regulated 5V supply connected to the charging input allows the onboard charger circuit to recharge the connected lithium battery.

5. Can multiple 18650 batteries be connected to this module?

Multiple compatible 18650 cells may be connected in parallel on suitable module designs to increase capacity, but they must be properly matched in chemistry, voltage, capacity, condition, and age. Cells must not be connected in series to a module designed for a single-cell 1S battery system.
