It's a universal law: Phones always conk out at inconvenient times. So preempt the problem! Keep a portable power bank on hand and you'll always have a way to juice up, even if you're not near an outlet. Thankfully, the most popular one at Amazon just dropped in price. The No. 1 bestselling Loveledi portable power bank bundle is $4 off right now. You'll get two power banks — we repeat, two power banks — for $20, both with 15,000mAh batteries. Just $10 a pop!

These power banks pack in a lot of charge into a thin (only 0.5 inch) frame. Sure, 15,000mAh sounds like a big number, but what does it actually mean? For most iPhones, that's about four or five full charges. The Pro series of certain iPhones have larger batteries and may only get three charges from one of these power banks. Considering there's two of them — and how small they are — you can carry multiple days of charge in a single pocket.

"Amazing battery life," confirms a shopper. "I have used it several times over the last week with only ONE full charge and I haven’t charged it yet with life in it still! I got the 2-pack deal and gave one to my mother as a gift..."

That portability is one of the major selling points. "I can’t be stuck at a charging station. I need to move around a lot. This has changed my life!" said one customer. "This power bank works great. It's lightweight and portable, thus can be taken anywhere. The charging speed is what really impressed me. I have several more expensive power banks but this one is just as powerful as those...," added another satisfied shopper.

The power banks include a sensor that automatically detects the voltage and amp requirements of a connected device. That means you never have to worry about damaging your phone with too much charge.

Did we mention these are also airline safe? Toss in your carry-on bag and keep your phone charged, no matter how many movies you want to watch while you're in the air. "Bought these when I was traveling on a plane for 15 hours. Charged my AirPods, phone and watch on one for almost two days," said one traveler.

Seriously, these are a great value. A single one of these will typically run you over $15, so getting two for $20 is a ridiculous deal.
