I'm always on the go, and I need a power source that keeps my tech running at full speed. Since I missed out on the discount during Amazon's Prime Early Access Sale, I've been stalking theAnker 737 portable power bank , hoping the price would drop from$150. This week, my wishes came true -- it dropped by$30 to only$120.

I've combed through plenty of portable power banks during the holidays, and Anker's has enough juice to keep my gear running for hours without needing to find a plug-in. It offers 24,000mAh power, and it can fully charge an iPhone up to 13 times, or an iPad Pro 1.3 times.

For those traveling during the holidays, navigating festival season, or living in an area prone to power outages, it's a handy way to ensure your laptop stays charged when you need it most. With over 800 reviews, its average rating is 4.6-stars. expert Adrian Kingsley-Hughes raved about the device in his hands-on review, saying, "the 140W output is a massive game-changer for keeping my MacBook Pro charged up when I'm out and about. The bright, crisp display adds value rather than being a gimmick, and the addition of a USB-A port along with the USB-C ports means that legacy devices don't get left out in the cold."

As a heads up, the last time this power bank dropped in price was during Cyber Monday. The deals on this power bank are usually far and few between, having sold out during Amazon's Prime Early Access Sale in October. In fact, I recommendadding it to your cart ASAP for that$120 price tag  -- because when it goes on sale, it sells out fast. You'll have to click the$30 coupon before adding it to your cart.
