I couldnt believe these were being sold at such a low price.Ive used all three adapters that I bought, and all work great ...on my iPhone 8, my wifes Samsung Galaxy 9 and all our Bluetooth devices that need charging ...like speakers, earbuds, etc. I would definitely recommend these adapters if youre looking to keep some extra around the house. I need to order more! I appreciate that Pulsetv.com doesnt load up the price on an item when they certainly could have. Thanks for a great product at a great price!
