If it’s too big to put in your pocket, what good is a portable power bank? The PowerCore Slim 5000mAh Portable Charger from Anker is just the right size for anyone who needs the extra power but doesn’t want to pack a bag or carry a big device in hand. Today, by clipping the coupon on its product page, you can snag one at Amazon for just $15,99. That saves you there almost 50 percent off its usual price, and it also brings this power bank lower than it has ever been reached before without a code.

PowerCore Slim from Anker lives up to its name with a slim, lightweight design that can easily fit into your pocket or almost any backpack or bag. It’s covered in a silicon anti-slip shield that you can rest assured you won’t scratch your phone, and it also helps to protect the power bank. There is a single USB-A port with a 2A output, and with a capacity of 5000mAh, you can get up to two full charges out of it when powering a phone like the iPhone 6s. Other, more powerful phones will obviously need more juice, so when you power up, you’ll want to keep that in mind.

This power bank offers an adaptive charge per device with Anker’s PowerIQ technology so that your phone or anything plugged in at the time will power up as efficiently as possible. With its purchase, a micro-USB cable is included to keep the power bank charged, although you will want to make sure that you have the correct charging cable to use with your phone. Such short USB-C cables are a great choice to use with your power bank, as well as short Lightning cables. PowerCore Slim’s purchase includes an 18-month warranty.

On orders totaling $25 or more, or with an Amazon Prime membership, shipping at Amazon is free.
