Amazon via AnkerDirect is offering the Anker Astro E5 15000mAh Dual-USB Power Bank for $39.99 with free shipping when you enter coupon code FM5FE4TP at checkout. That’s $10 better than the average selling price and nearly the same as past deals for lower-capacity models.

Dubbed the ‘biggest, baddest battery in the Anker mobile line,’ the Astro E5 features enough juice to provide seven charges to an iPhone and nearly one full iPad charge. Dual-USB ports allow for simultaneous charging of two devices. Rated 4.5 out of 5 stars from 1,199 Amazon reviewers.

It doesn’t include device-specific adapters so be sure to add an extra 30-pin or Lightning cable to your shopping cart before checking out.
