Bought a 32 GB large size model for GF for birthday (no 4G). First one doesn't charge. Amazon ships a replacement (and free charger brick - good on you Amazon) that charges OK but has flaky power switch. Third unit to arrive tomorrow and hopefully third time is the charm.
There's a reason they recommend their charger. It puts out 1.85 amps and to get a full charge in 4 hours you need all that juice. If you're a buyer jump on the 1/2 price charger at checkout - you'll be glad you did. -- Time is an abstract concept invented by carbon based life forms to monitor their constant decay.-Thunderclese
I have kindle fire hd I went out to the store this week to pick up a kindle powerfast because without it takes forever to charge with a regular usb charger the kindle powerfast is much better.
