Anker 737 Power Bank, 140W Max 3-Port Laptop Portable Charger, 24,000mAh, Smart Display, Compatible with iPhone 16 / 15 / 14 Series, Vision Pro, Samsung, MacBook, and More

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.

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.

I needed a charger that would reload my iPad Pro. I have a couple of quite powerful battery packs, but the best of them struggled even to maintain the iPad charge at the same level (though it does well in recharging my iPhone). So, more power needed. This battery is a chunk, It’s big and heavy. When I first got it, the booklet advised putting it on charge right away and, yes, that is needed. The display showed it at only 16% of full charge out of the box. I put it on a regular 3amp (about 15w) charger and the display usefully, if rather disappointingly, predicted it would take about 16 hours to full charge (It did start at 99 hours immediately, but then it got its act together and gave a more manageable timeframe though the timing does bounce around a bit). I left it on charge overnight and it was 100% the next day, so I’m guessing around 12 hours from 16% to 100%. I would have preferred faster, preferably a lot faster. But Est Quod Est… In my first trial at using the battery to charge my iPad the iPad was at 83% and the battery at 100%. It charged the iPad up to 100% in maybe 45 minutes which ran the battery down to 92%. So a 17% iPad charge resulted in an 8% run down on the battery, About a 2:1 ratio. That implies I should get two whole iPad charges out of one full battery charge and the charging should take about 6*45min or about 4.1/2 hours. Not too bad. Again. I would have preferred more charge for a shorter time. But this was only my first pass at calibrating the charging capability of this battery, so we’ll see how it pans out in the longer term. In the meantime, I really like the display. It shows the current draw, predicts charging time and shows the current charge level of the battery—all very useful metrics. It is chunky and quite heavy, which somewhat detracts from its portability, but more powerful batteries are always bigger and heavier. That’s just the way it is. My interim judgement is that it’s a plus and assuming it is able to reliably deliver charges to my iPad for a good number of battery recharge cycles, I will be happy I got it. I may update these metrics after I’ve run it for a while, but for now: recommended.

This power bank exceeded my expectations. It delivers excellent power and easily charges laptops, tablets, and smartphones. The charging speed is fast and stable, and the built-in display is very useful for monitoring battery level and output power in real time. The design feels solid and high quality, making it durable and reliable. Perfect for travel, remote work, or long days away from home. Definitely worth the investment.
