If your powerbank is not performing as expected, the steps below can help resolve the most common issues quickly.

Before proceeding, we recommend reviewing:

• Is This Normal? — Powerbank Behaviour Explained
• Why Your Powerbank or Charger Feels Warm

Many concerns are often related to cables, chargers, or device requirements rather than the powerbank itself.

 

Powerbank Not Charging or Battery Percentage Not Increasing

The steps below apply to most Chargeasap powerbanks with USB-C charging.

Step 1 — Check the Cable and Charging Port

  • Test your USB-C cable with another device to confirm it is working correctly.

  • Ensure the cable supports the required wattage for fast charging.

  • Inspect the charging port and confirm the connection feels secure when plugged in.

  • If available, try a different cable and wall charger to compare results.

Many charging issues are caused by cables or power adapters rather than the powerbank.

 

Step 2 — Test While Connected to Wall Power (Passthrough Charging)

  1. Plug the powerbank into a wall charger and leave it connected for approximately 30 minutes.

  2. While it remains plugged in, connect a phone or tablet to one of the output ports.

Check whether:

  • The connected device begins charging

  • The powerbank battery percentage increases

Make a note of what you observe.

 

Step 3 — Reset the Powerbank

Press and hold the power button for 15 seconds to perform a reset.

This helps recalibrate the internal power management system.

 

Step 4 — Confirm Your Wall Charger Is Suitable

Recharge speed depends heavily on the wall charger being used.

Lower-wattage chargers will recharge larger-capacity powerbanks more slowly.

For best results:

  • Use a high-output USB-C charger

  • Pair with a high-wattage cable

  • Avoid low-power phone chargers for large powerbanks

When paired with an appropriate high-output charger, many Chargeasap powerbanks can recharge in a fraction of the time compared to standard battery packs.

 

Step 5 — Still Not Working? Record a Short Video

If the issue continues, a short video helps our team assess the behavior faster.

Please keep the video under 2 minutes and show:

  • The port you are using

  • The cable connected

  • The charging attempt

  • Any ports that are functioning normally

Upload via WeTransfer, Google Drive, or Dropbox and include the link when submitting your request.

 

Step 6 — Include These Details

Providing the information below allows us to assist you more efficiently:

  • Wall charger used (example: 140W USB-C charger, laptop charger, etc.)

  • Cable used

  • Order number

 

Powerbank Is Not Recharging

If the powerbank does not appear to recharge:

  • Confirm the wall charger is functioning

  • Try a different outlet

  • Test another USB-C cable

  • Ensure the charger provides sufficient wattage

Large-capacity powerbanks require higher input power and may recharge slowly when paired with lower-output adapters.

 

Charging Speed Seems Slower Than Expected

Charging speed is influenced by several factors:

  • The device’s supported charging limit

  • Cable capability

  • Wall charger wattage

  • Battery level of the connected device

  • Temperature conditions

It is normal for charging speeds to slow as devices approach full battery capacity.

For the fastest performance:

  • Use high-wattage chargers

  • Use certified cables

  • Disconnect unused devices

 

Wireless Charging Not Working

If wireless charging is not activating:

  • Confirm your device supports wireless charging

  • Ensure wireless charging is turned on — activation methods can vary by model

  • Check your product guide or instruction manual for model-specific steps

  • Reposition the device on the charging surface

  • Remove phone cases

  • Ensure the powerbank has sufficient battery

Wireless charging requires proper coil alignment, so adjusting the device slightly may help establish a connection.

 

One Port Isn’t Working

  • Test the port with another cable

  • Try charging a different device

  • Check for dust or debris in the port

  • Confirm the cable fits securely

Power output may adjust automatically when multiple devices are connected.

Testing ports individually can help isolate the behavior.

 

OLED Display Is Not Turning On

For models equipped with an OLED display:

  • Press the power button once to activate the screen

  • Connect a device to trigger display activity

  • Recharge the powerbank if the battery is fully depleted

  • Allow a few minutes of charging before attempting to power the display

Some models use power-saving features that turn the display off when not in active use.

If the Display Still Does Not Activate

  • Try a different charging cable and wall adapter

  • Confirm the wall charger is functioning

  • Press and hold the power button for 15 seconds to perform a reset

Resetting helps recalibrate the internal power management system and may restore display function.

 

Powerbank Stops Charging Temporarily

If charging pauses or resumes:

  • Check whether the connected device has reached full battery

  • Disconnect and reconnect the cable

  • Test another cable if available

Temporary pauses can occur as devices negotiate power requirements.
