A4C offers the bulk-packaged Amazon Kindle 5-watt USB Power Adapter, model no. 53-000777, bundled with a 5-foot Micro-USB Cable for $4.95 with free shipping. That's the lowest total price we could find for the adapter and similar cable separately elsewhere by $13, although we saw the adapter alone for a buck less last week. This 1-amp adapter folds for storage and is approved to work with most Kindle devices. Deal ends July 31.
Of note, this item is new but does not ship in its retail packaging.
