Verified Purchase(What is this?)
This review is from: Liying iPhone 4/4s 2200 mah external rechargeable spare backup extended battery charger pack case cover for Apple iPhone 4s - BLACK (Electronics)
This product is, simply put, pathetic. Despite being 2200 mah it retains insufficient charge to rec-charge an iPhone 4s once. IN addition the product gets unacceptably hot when charging. The product has certain instructions/endoresements on the rear - most of which are spelt incorrectly.
Having lodged a complaint and returned the article - the vendor is engaging in deliberate obfiscation to avoid having to refund the purchase price.
Do not buy this product and do not buy from this vendor.
