There’s nothing worse than your phone running out of juice before the end of the day, so a power bank in your bag or jacket pocket is always worth it. Thanks to its slim design, this mobile RAVPower charger with USB-C is ideal for getting on the go and right now you can snag it at its finest cost when you tap the coupon on its product page and then enter the TVAN4Q56 promo code during checkout.

That drops it down to $20.64 which is smaller than we’ve seen it go before, although you’re going to need an Amazon Prime membership to snag the highest cost possible. Without Prime, your total will be $21.99, which is still smaller than otherwise reached by this charger.

It is capable of charging most smartphones with a capability of 10,000mAh two to three times over which is more than enough to get you through the heaviest day of use. It has a Quick Charge 3.0-enabled USB-A port for supporting phones, as well as a Power Delivery USB-C port up to 18W for quickly charging compatible devices. Whatever phone you’re rocking, you’ll be able to get powered up and maybe even offer some juice to a buddy at the same moment. There is a Micro-USB port to back up the power bank itself or you can use the same USB-C port to make it even faster.

This power bank hasn’t been accessible for a long time, although over 85 client reviews at Amazon have already earned a score of 4.5 out of 5 stars.
