Why does my cordless heating blanket charge but not switch on?

If the power bank charges but the blanket will not start, the issue may be with the on/off switch, the USB connection, or the power bank not being fitted correctly. Stop using it if you see heat around the connector, damaged cable sheathing, or any sign of overheating.

Check the basic power path

1. Make sure the power bank has been charged fully.
2. Fit it back into the blanket as intended and reconnect the USB cable securely.
3. Press the on/off switch and test each heat setting one by one.

These cordless models use a switch and USB power supply, so a poor connection can stop the blanket from starting even when the bank itself appears charged.

Interpret the result

1. If the blanket starts after reseating the cable, the original connection was likely loose.
2. If there is no response on any setting, try a different charging lead only if it is clearly suitable and undamaged.
3. If the blanket powers intermittently, stop testing and do not keep cycling the switch.

Stop using the product if

• The connector area warms up
• The switch feels stiff, loose or inconsistent
• The blanket makes unusual noises, smells hot or works only briefly

If the blanket still does not switch on after these checks, stop using it and contact the retailer or store where it was purchased. The retailer can explain the available next steps.
