What Is the IP5306? Power Bank SoC (Charge+Boost+Gauge) and Uses

October 28, 2026 5 min read
Quick answer

The IP5306 is a power bank SoC: it combines Li battery charging, boost to 5 V output and a 4-LED battery-level gauge on one chip (5 V/~2.1 A). It is the standard chip of 18650 power bank modules. WATCH OUT: it usually has no battery protection circuit (use a protected 18650) and a 'low-current shutdown' can turn off low-consumption devices.

The IP5306 is a power bank SoC: it combines Li battery charging, boost to 5 V (output) and a battery-level indicator (4 LEDs) on one chip. It is the standard chip of 18650 power bank modules. For the concept, see voltage regulation / power management.

What is the IP5306 used for?

DIY power banks, adding "charge + output 5 V + show level" to battery-powered devices with one chip. It charges the battery from USB input; outputs 5 V/~2.1 A; shows charge status with LEDs on a button press. The I2C version allows configuring settings.

Watch out

IP5306 modules usually have no battery protection circuit; use a protected 18650 or a separate protection board. A "low-current shutdown" feature can auto-turn-off some low-consumption devices (e.g. a sensor node) — mind this behaviour.

Equivalents

  • IP5306 I2C: the software-configurable version.
  • TP4056 + MT3608: a discrete charge + boost solution.
  • IP5310 / IP5328: higher-power power bank SoCs.

Frequently Asked Questions

What is the IP5306?+
The IP5306 is a power bank SoC: it combines Li battery charging, 5 V boost output and a 4-LED battery gauge on one chip. It is the standard chip of 18650 power bank modules (5 V/~2.1 A).
Does the IP5306 protect the battery?+
Usually no; its modules have no protection circuit. Use a protected 18650 or a separate protection board.
Does the IP5306 shut down at low current?+
Some versions have a low-current auto-shutdown; it can turn off devices that draw very little current (a sensor node). The I2C version lets you configure this behaviour.
What is an IP5306 equivalent?+
The software-configurable IP5306 I2C; the discrete solution TP4056 + MT3608; the higher-power IP5310/IP5328.
