The Battery Cannot Be Charged Or Charged Slowly.
| ANALYSIS OF CAUSES | SOLUTIONS |
|---|---|
| The wire is connected to the wrong input port of the battery. | Plug the Type-C (USB-C) end to the battery's side port. When "%" flashes on the display, it's charging! |
| The charging adapter does not match the battery standard. | Too-low power is difficult to input into our battery. It is recommended to choose a suitable fast charger such as 5V⎓3A / 9V⎓2A / 12V⎓1.5A. |
| Using the wrong slow charging adapter. | A slow charge of 5V⎓2A takes a whole night, while a fast charge of 5V⎓3A / 9V⎓2A / 12V⎓1.5A only takes about 4 hours to fully charge. Suggest using fast charging. |
| Insufficient battery maintenance. | Do not leave it sitting for too long without charging. It's best to charge it every 1-3 months while also avoiding overcharging. And store it somewhere cool and dry to keep it in top shape. A little battery drain when it's idle is totally normal. |

AFTER CONNECTING THE POWER BANK TO THE PLUG INSIDE THE GARMENT, THE GARMENT DOES NOT HEAT UP OR ONLY HEAT AT A LOW TEMPERATURE.
| ANALYSIS OF CAUSES | SOLUTIONS |
|---|---|
| Power bank not connected or insufficient charge. | Ensure the power bank is fully charged and properly connected to the garment. |
| Loose connections | Check for loose connections and ensure a secure fit. Make sure the metal part of the plug is fully inserted into the port. |
| The power bank is simultaneously connected to other devices. | Please remove all charging devices from the power bank, and then restart the power bank and reconnect it to your garment properly. |
| Voltage mismatch issues when the battery is not compatible with jacket. | Use the recommended power bank provided by our brand to match your heated garment. A 7.4V battery cannot support a 12V heating jacket; And using a 12V battery on a 7.4V jacket may over-heat those heating elements. |

UNEVEN HEATING OR LOCALIZED AREAS NOT HEATING.
| ANALYSIS OF CAUSES | SOLUTIONS |
|---|---|
| Improper connection | Check for loose connections and unplug the power bank, reconnect it to the garment properly. |
| Verify battery charge | Make sure the battery is sufficiently charged (at least 50% recommended). |
| Test heating levels | Short press the power button to switch between heating levels, observe any changes, and try waiting on the high setting to allow the heating elements to warm up. |
| Ensure the garment is worn snugly | Loose contact with the body may feel uneven. The heating areas close to the body, such as the neck and back, may feel warmer, while areas like the pockets or arms, which have more space from the body, may feel slightly warm. |
| Inspect for bends or damage | Check the inside of the garment for any bent, pulled, or damaged wires. |
