ESR has issued a recall for 33,000 HaloLock wireless power banks, in 6,000mAh and 10,000mAh versions, because their lithium-ion batteries can “overheat and ignite, posing fire and burn hazards to consumers.” The power banks were cheaper alternatives to Apple’s MagSafe accessories (priced between $32 and $40) but offered slower 7.5W wireless charging speeds when used with an iPhone. Other Qi2 compatible chargers offer at least 15W speeds.

The company has received nine reports of the power banks catching fire and exploding, causing around $20,000 of property damage, but no injuries, according to the US Consumer Product Safety Commission (CPSC). Although the exact model number wasn’t revealed, seven months ago, a Reddit user shared images of the aftermath of a power bank exploding and catching fire in their home, which they later identified as an “ESR 10000 mah wireless portable charger.”

Approximately 24,000 power banks were sold in the US through Amazon, Home Depot, and ESR’s online stores between September 2023 and July 2025, plus an additional 9,000 in Canada.

This recall involves ESR HaloLock wireless power banks with model numbers 2G520, 2G505B and 2G512B. “ESR” is printed on the back and the model number is printed on the right side of the pocket-size power banks. They were sold in dark blue, light blue, gray, white and black. All recalled models have five circular LED display lights on one side.
