A Kindle charger keeps the battery running on your Amazon Kindle or Kindle Fire. Kindle chargers come in standard electric socket versions or car charger versions. A Kindle e-reader has a battery that lasts a long time on the small power drain that reading e-books causes, but it still requires recharging periodically.
A Kindle Fire is a tablet rather than an e-reader, and has a shorter battery life due to its multiple uses. If you need a replacement Kindle charger or a car charger for your Kindle, you can find them on eBay. Keep your Kindle running well with a Kindle charger.
