The recalled charger can be identified by looking for its model number, BPD005, printed in white text on the back of the charger, behind its Apple Watch charging pad. There have been no injuries reported as a result of the issue, but Belkin says that consumers should immediately stop using the charger, disconnect it from power sources and other devices, and place the BoostCharge Pro in a “safe, dry location away from anything flammable or anything that can damage the power bank.”

Instead of replacing the BoostCharge Pro, Belkin is offering full refunds through an online recall form that requires the power bank’s serial number, located on the back near the model number. If the serial number is missing or illegible, a “copy of the purchase receipt and photo showing the front and back of the power bank” will need to be provided for refunds to be approved.

Belkin also cautions against discarding the power bank in a trash or recycling bin. That can cause fires, and further contribute to the growing e-waste problem. The company says that customers with approved refund requests will be emailed instructions for safely disposing of the power bank, and not to dispose of them before then. But products with lithium-ion batteries should be taken to facilities that can safely dispose of them. In the US, locations that will recycle power banks like this can be found through the Environmental Protection Agency’s website or other organizations that specialize in handling e-waste.
