UPDATE: 1Sale is already sold out of the Anker charger. It is still available on Amazon for $39.99
1Sale is offering the Anker 10,000mAh Power Bank Portable Charger for USB Devices for only $29.99 shipped. That’s 71% off the list price and the best price we’ve seen. Amazon sells it for $10 more and their customers rated it well with 4.5/5 stars and excellent reviews. The Anker features a 10,000mAh capacity (That’s enough power to charge the iPhone 5 up to five times or to fully charge your iPad once), 2 USB ports, and it’s compatible with almost any device that uses a USB charger.
Also, if you’ve ever wondered if your USB cords have gone bad or if they’re even dangerous to keep using, Amazon has the Power Practical Meter with Fast-Charge Cable that can test if your cables are faulty or too dangerous to use on your devices. It currently sells for only $19.49.
