This is an awesome device. After some quick tests I can say it fully meets my needs and expectations. Yes, it is expensive, and at $150 I didn't think I could justify it. I got it on sale for $100 and I believe it was definitely worth it. The display is fantastic and really provides all the information you need in order to know what is going on with the inputs and outputs. My main use will be for charging the 50wh battery in my Surface Pro 8. The Anker 737 will charge it at a 55w rate via either of the two Thunderbolt ports (the supplied Microsoft charger is rated at 60w through the Surface connector), and it appears that the conversion efficiency is about 80%, meaning that it can fully charge the Surface and have capacity left over to charge a phone or two. (An interesting note about conversion efficiency based on some quick tests and calculations: If I charge my Surface Pro 8 from my Jackery 300’s PD port, it takes about 60wh to fully charge the 50wh battery. It appears that the Anker 737 will need to supply almost 70wh to fully charge the 50wh battery. If I connect the Microsoft AC adapter to the Jackery 300’s AC port and charge the Surface that way, it requires about 90wh to fully charge the 50wh battery. The more up and down conversions you do, the more you lose.) The supplied cord is rated for 140w and is 60cm long (NOT 6 cm as some have said), or about two feet. I had limited success with pass-through charging, YMMV. I connected a 45w charger and the Anker started charging at 42w. Then I connected a phone, which started charging at 10w, but the input to the Anker then dropped to an identical 10w. A different charger and a different load might give different results, I don't know. Others have complained about having difficulty charging DJI batteries. Here's what I think is going on (my best guess, anyway): I have the Mini 2 battery charging hub and three batteries. The hub appears to be happiest with an input of 12v, 1.5a. (The supplied DJI charger is rated at 9v, 2a and 12v, 1.5a.) USB-C PD 3.1 does not appear to support 12v, and when connected to the hub, the hub and the Anker can't seem to negotiate an 18w charging rate at 9v. HOWEVER, when I connect the hub to the Anker's USB-A port using the supplied DJI cable all is well and the hub charges at 18w. Some users have panicked over the USB-A port showing 0.1a with no load connected. Anker explains this on their support page (which takes some digging to find). 1. Make sure Trickle Charge mode is off (tap the button twice). 2. Wait two minutes after disconnecting a load from the USB-A port. 3. Relax. Some users have experienced less than expected charging rates. Not all USB cables are created equal. (In fact, back in the early days of USB-C there were some cables that didn’t meet the standard and were risky to use.) Make sure your cable supports the rate your device requires. I bought a six foot, 140w Anker cable to go along with the 737. That, plus the cable supplied with the 737, should meet all my needs. Read more

This power bank is extremely reliable and well-made. The 24,000mAh capacity provides plenty of power, and it charges devices quickly and efficiently. The build quality feels solid and premium, exactly what you expect from Anker. The display is useful for monitoring battery status, and having multiple ports makes it convenient for charging more than one device at a time. Great for travel, work, or everyday use. Overall, an excellent power bank with strong performance and dependable quality. Read more

The main reason for purchasing this is to charge my M1 MacBook Pro and 2017 12.9 Inch iPad Pro simultaneously. When I originally got the power bank I charged it back up to full capacity. I ran into a few minor issues with the charging of my iPad Pro in terms of speed but it has calmed down as of late. I've run quite a few tests to see what it's capable of.

Pros - Recharges quickly with a 100 Watt or higher charger(sold separately) - Recharges laptops at full speed and can trickle charge two high-end laptops - Smart display indicates tons of useful information such as battery percentage and wattage charging - Small enough to fit into a backpack Cons - Expensive($149.99) - Doesn't come with a wall charger - Occasionally has issues charging 2017 iPad Pro Overall, if you have a high-end USB-C laptop such as the 16-inch MacBook Pro, this is the best choice to go for in the sub-$200 range.
