Fortunately, there are about a million more power banks on Amazon right now that won't catch fire. Amazon has also received 4 reports of property damage from fires and smoke. The affected units post a fire hazard which is why they're being recalled.
The product documentation states the power banks were made in China by Guoguang Electric Company Ltd.

The power banks were sold with or without a USB charger cable and a carrying pouch. 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.
