The Office for Product Safety and Standards (OPSS) issued a product recall on 26 November 2025 for ESR HaloLock wireless power banks sold via Amazon, covering models 2G520, 2G505B and 2G512B1. The affected products were sold in the UK between October 2023 and August 2024, and the recall applies to units already with end users1.
The power banks are described as lithium-ion battery power banks in various colours, with China given as the country of origin1. The notification lists 16 barcodes covering the affected units, including 4894240179031, 4894240168479, 4894240168462, 4894240132579, 4894240179024, 4894240132586, 4894240201022, 4894240201015, 4894240201657, 4894240201039 and 48942401325551. The recall carries the PSD notification number 2511-02171.
The hazard is fire. The OPSS states that the batteries can overheat during use, which "can cause the power bank to enter into thermal runaway, causing a fire"1. The notice says the product does not meet the requirements of the General Product Safety Regulations 20051.
"We advise owners to stop using this product immediately and visit the ESR website for more details"
The OPSS gives the ESR recall page at uk.esrtech.com/pages/recall for further details1. The notice does not state how many units are affected in the UK, and no injuries or incidents linked to the product have been reported in it1.
Why it matters for households
These are rechargeable power banks intended for charging phones and other devices, including as backup power during outages. Anyone who bought one of the three models through Amazon between October 2023 and August 2024 may hold an affected unit, and the OPSS advises owners to stop using it immediately and to check the ESR website1. Because the risk arises during use and charging, an affected unit kept for emergency backup is within the scope of the warning. Households unsure whether a power bank they own is covered can check the model number and barcode against the recall notice, and our guide on how to check if an electrical product has been recalled sets out where recall information is published. Our page on whether batteries and chargers from online marketplaces are safe covers the wider issues with marketplace-sold electrical goods, and Power Banks: Keeping Phones Charged in an Emergency explains how these devices are used in a power cut.
What happens next
The recall was published on 26 November 2025 and remains in force; the OPSS directs owners to the ESR recall page for details of the remedy1. The notice does not set out a deadline or describe the replacement or refund process, which has not been reported1.
