The watchdog for safety and quality of consumer products in the United States said about 260,000 units of six kinds of power banks - manufactured in China by Guoguang Electric Co Ltd for Amazon's "Basics" lineup - were part of the recall.
Amazon offers a line of its own products under the "AmazonBasics" brand.
E-commerce giant Amazon issued a voluntary recall Wednesday on several of its AmazonBasics-branded portable charging power banks, citing concerns over the devices overheating and melting and starting fires.
The chargers, which sold from December 2014 through July 2017 at Amazon.com, Amazon Bookstores and Amazon Pop-Up Stores, retailed for between $9 and $40. Owners should stop using these recalled units immediately.
They have capacities of 16,100mAh, 10,000mAh, 5,600mAh, 3,000mAh, 2,000mAh with Micro USB cable, and 3,000mAh with Micro USB cable.
All listings for these power banks have already been removed from the Amazon website and they can no longer be purchased. They are rubberized or metallic black and measure roughly 3-by-1.4-by-0.9 inches and carry the product ID numbers B00LRK8EVO, B00LRK8HJ8, B00LRK8I7O, B00LRK8IV0, B00LRK8JDC, or B00ZQ4JQAA.
The report says the recall is being done in partnership with the US Consumer Product Safety Commission, although a recall notice hasn't been posted to their website yet. All known purchasers are being contacted directly by the firm. If you didn't, then contact Amazon directly toll-free at 855-215-5134 from 8am to 5pm ET Monday through Saturday.
The affected batteries are all Amazon's low-priced AmazonBasics brand.
