Why is this a good deal?

This power bank — called "the little charger that could" by one reviewer — can charge your phone to 100% in just one hour. It also has a USB-C cord built right in, which makes it an even sweeter deal. Anker has plenty of brand recognition, and similar power banks with built-in cables often go for more. The $12 off is icing on the cake.

Why do I need this?

If your phone is always running out of juice or you need a reliable, compact power bank for travel, the Anker Nano is well worth the investment. It has a vibrant color display and two-way charging, which means the power bank itself can be charged up just as fast as your devices. What really sets it apart, though, is its durable built-in USB-C cable. Yep — you'll be able to use this tiny power bank to charge your phone, laptop, tablet or other compatible devices while you're on the go without even having to remember a charging cord.

The built-in cable also has fast-charging abilities, so you'll be able to juice up your tech faster than you could using a traditional charger or power bank. Also, regarding that vibrant display — this one is actually useful. It shows you how much time is left before your device is fully charged, plus exactly how much power remains on the battery.

What reviewers say:

Though it was just released in August, this power bank is already a shopper favorite with more than 700 five-star ratings.

"This power bank checks all the right boxes," one shopper raved. "It's compact, portable, convenient to use, has a good selection of ports, looks amazing, has good capacity, and charges fast. I can't think of any other charger that has all of these together. The 10K capacity is also the sweet spot between size and capacity, which is a huge plus."

"This little beast is the Clark Kent of the charging world," said another happy user. "It's small, unassuming, and looks like it couldn't charge a lemon, let alone your tech, but oh, how wrong you'd be! ... The built-in cable means I'm no longer playing Indiana Jones on a daily quest to unearth my charger." As for power, "I've charged my phone, my tablet, and even dared to lend it to a friend in the middle of a power-out gaming marathon. It performed like a champ."

"Took this to France and the UK recently and it did an outstanding job charging up two iPhone 15 Pros on the go," a globe-trotting user said. "Compact and lightweight enough to fit into a small purse. Love the display with current battery percentage shown, and it was never a problem to refill it up at the end of the day. Also, no problems passing museum security screenings with this charger in the purse."

The cons for this portable staple were few and far between, but one shopper noted that they wish the screen "stayed on all the time during charging" without having to press a button to check it.
