As a power-hungry tech journalist, I’m constantly on the lookout for good bargains on portable power to keep my devices charged while I’m traveling for work. So, I snapped up Anker’s 24,000mAh 737 Power Bank when I saw it on sale at Amazon for $73.99 — which is more than 50 percent off the original retail price. It’s also available directly from Anker for the same Black Friday low when you use promo code WS24SJHXE0JN at checkout.

I’ve been looking for a good power bank that could simultaneously charge my MacBook Pro, iPhone, and headphones while on the go, and I’ve had my eye on the Anker 737 for a while. Its whopping 24,000 mAh battery means I can ditch my other less powerful power banks and seriously streamline my go-bag (although at 1.6 pounds, it won’t make it much lighter.) Still, not having to hunt down a power outlet at the airport or deal with those janky sockets on the plane will be worth the extra weight.

Anker’s three-port portable charger features a digital display and 140W output, making it perfectly suitable for charging smartphones, laptops, and headphones simultaneously.

Although it normally runs $149.99 and has recently been on sale for around $109 at Amazon and elsewhere, its current price of $73.99 is the lowest I’ve seen. The GaN charger can fast charge itself at 140W and power other gadgets at that rate, which — according to Anker — means it can charge a 16-inch MacBook Pro to 50 percent in 40 minutes (with the right cable) and fully charge a newer iPhone up to five times.

Its two USB-C ports supply 140W of power each, and its single USB-A port supplies 18W. It also features a built-in display that shows how much power is left, how much a device is drawing, and how long it will take to recharge. All this info should make it much easier for me to stay powered up wherever the tech takes me.
