iClever has a pretty great deal on an interesting power bank. This one not only recharges your smartphone, but it can also jump start your car, which is pretty impressive in its own right. Typically, this would go for around $64, but right now if you use the promo code ICJP0311 at checkout, you can pick it up for just $54.
This iClever 15,000mAh Portable Car Jump Starter/External Power Bank is pretty powerful, as you might expect. It can jump start up to a 6-cylinder engine, and it can also power up your smartphone or tablet. With there being a 15,000mAh capacity, you'll be able to charge your smartphone around 4-5 times before it runs out of juice. While we don't always need a jump starter for our car, it is still nice to have one available, just in case the battery dies. And this way, you don't need to ask a stranger for help. As an added bonus, iClever has added a flashlight onto this battery, allowing you to use it in the dark and actually see what you're doing, always helpful.
It's unclear how long this price is going to last on the iClever 15,000mAh Portable Car Jump Starter/External Power Bank, but it likely won't be long, so you'll want to pick yours up before the price goes back up.
