A4C offers the Griffin PowerDuo 1,000mAh Reserve Charger and Backup Pack for Apple iPhone and iPod for $6.95 with free shipping. (BESTpriceBRAND via Amazon offers it for pennies more with free shipping for Prime members.) That's tied with our February mention and the lowest total price we could find by $3. It includes both a wall and car charger and should work with most devices that charge via USB. Deal ends April 30.
