DESCRIPTION AND FEATURES

Introduction

This IP5407 Type-C + Micro dual-input power bank module is packed with a high-efficiency core IC. It supports 2.4A fast charging via two USB ports, so you can power up two devices at the same time. Plus, the 4-LED real-time battery display lets you see how much charge is left at a glance.It comes with multiple safety protections—overcharge, over-discharge, short-circuit, and over-temperature safeguards—so you can use it worry-free. It works with 3.7V 18650 lithium batteries, and the solder-free design means even beginners can assemble a custom power bank in just 15 minutes.For only a few dollars, you get a practical, DIY-friendly power bank that’s perfect for daily use or emergency charging. It’s super reliable!

IP5407 Datasheet

If you want to learn more IP5407 power bank module details, you can refer to this datasheet.

Product Precautions

  1. When you receive the main board, first test it with a charger to check if the LED lights up.
  2. For normal use, the battery must be soldered (twisted wires will cause insufficient power supply). Reversing the battery connection will definitely damage the board—please be extremely careful.
  3. The wires between the battery and the board shouldn’t be too thin; use thicker wires (capable of handling 5A current). Also, don’t use overly long wires, and the connectors must be soldered.
  4. Batteries can only be connected in parallel, not in series. Series connection will definitely damage the board.
  5. Make sure the battery is in good condition. If the battery shows full charge immediately after being connected, but can’t discharge when a phone is plugged in, the battery is most likely old and worn out.
  6. Do not add a protection board to the battery. Some batteries (not designed for power banks) have built-in protection boards that limit current—they may cut off output if the current exceeds 1-2A.
  7. Reversing the board’s connections will definitely damage it (damaged ICs will show visible signs). This only happens due to reverse connection, and we won’t be responsible for issues caused by reverse connection.
  8. The Type-C port is for input only, not output.
  9. “Input current” refers to the battery’s input current.

Common Questions

What Type of Battery Should I Use?

We recommend 3.7V lithium batteries (typical operating voltage: 3.0V to 4.2V). Do not mix old batteries of different capacities or brands. For used/second-hand batteries, ensure each has a minimum voltage of 3.5V—batteries with lower voltage will not charge when installed.

Unsupported Batteries: Alkaline batteries, lead-acid batteries, 1.2V rechargeable batteries, nickel-metal hydride (NiMH) batteries, 3.2V lithium iron phosphate (LiFePO4) batteries, etc.

How to Distinguish Between Battery Terminals and Case Terminals?

For most 18650 batteries: the flat end is the negative terminal, and the end with a small hole is the positive terminal. Never reverse the polarity—this will damage the module permanently, even if you correct it later. For polymer batteries, the red wire is usually positive and the black wire is negative, but this isn’t universal. When in doubt, use a multimeter to check the voltage.

Why is There No Power Output After Installing the Battery?

After installing the battery, you need to connect a 5V charger to “activate” the module before it can output power.

What Is the Actual Conversion Efficiency?

For new, fully rated batteries, the conversion efficiency is approximately 85%–92%. Some power loss occurs due to connecting wires (loss = resistance × current²). Charging cables also contribute significantly to power loss.

How Long Does It Take to Charge the Battery?

Charging time depends on the battery capacity, charger power, and cable quality. As a general guide:Charging time (minutes) = (Battery capacity × 1.2) / Charger current (mA) × 60.

Troubleshooting

The module gets very hot

First, judge how severe the overheating is—mild heat is normal. Heat increases with charging power, because voltage conversion has energy loss (which turns into heat, related to efficiency). This is a common issue (one reason phone charging power increases slowly: iPhone 7 still uses 2A/10W charging). If the board works normally (no unexpected battery drain or overheating when idle), and it’s not too hot (check charging power), it’s safe to use—chips have built-in overheat protection.

Battery level display is inaccurate

After connecting the battery, you need to fully discharge and recharge it at least once (sometimes multiple times) for the level display to become accurate.

The light flashes on then off, or charging stops shortly when charging a phone

  1. First, check if the battery has power (use a multimeter).
  2. Check the wiring: Ensure the battery and board are soldered properly (twisted/clamped wires won’t work). Use thick wires (copper wire or nickel sheets) to avoid insufficient current.
  3. Check if the battery has a protection board: Some batteries have built-in protection boards (not designed for power banks) that limit current—they may cut off output if current exceeds 1-2A. Remove the protection board if present.
  4. Check the battery: Old batteries with high internal resistance may cause this. Replace the battery if needed.
  5. Check the charger: A low-current charger may also stop charging early.

Slow battery charging or incomplete charging

  1. First, check if the battery voltage reaches the full-charge voltage (usually 4.2V). If not, keep charging.
  2. If the voltage is already 4.2V but charging still shows as active: The battery may have poor balancing. Try fully discharging it, then recharging (repeat a few cycles).
  3. Check the wiring: Ensure the battery and board are soldered properly (no twisted/clamped wires) with thick wires (copper wire or nickel sheets).
