Keep your iPhone from dying with 60% off this portable battery

I want you to close your eyes and visualize your smartphone at 3% of a full charge. There's a tiny red sliver left in the little battery icon, and you're without a charger. The possibility of having to endure a bus ride home without your phone is very real.

Now I want you to close your eyes and visualize this scenario never happening again.
It might seem obvious, but the trick to keeping your smartphone juiced is to simply always have a charge within reach. Lucky for you, Amazon just slashed 60% off a massive portable charger from Anker, as well as 50% from a pack of three Anker Lightning cables.

Durable, reliable, and super-slim—what more could you ask for in a portable charger? (Photo: Anker)

We've written about Anker's stellar portable chargers in the past, and there's a reason we keep coming back to them—simply put, they're the best option when you're on-the-go and your phone needs a pick-me-up. The enormously discounted Anker PowerCore 10400 has enough juice to charge your phone at least twice and is small enough to slip in your purse, backpack, or pocket—all for just $20 (60% off its usual price).
And, if you're wise enough to take advantage of Anker's pack of three Lightning cables (now 50% off), you can plug 'em into your bedroom, living room, and office and forget about them forever. No more battery anxiety; no more dead iPhone.
A charge in every room and a spare battery in every bag—all for just $40. How's that for a slice of fried gold?
