Anker 737 Power Bank, 24,000mAh 3-Port Laptop Portable Charger with 140W Fast Charging, Smart Display, for Outdoor Work, Compatible with iPhone 16/15/14 Series, Vision Pro, Samsung, MacBook, and MoreClimatePartner certified

This is a great power bank so far. I’ve been able to charge both my laptop and phone at good speeds. The 140W output sounds impressive, but honestly, very few devices can take advantage of that. If that’s not your main reason for buying, you might find other options just as good.Anker is known for quality products, and this is no exception—it feels very well-built and solid. I love that it shows the charging speed and how much power each device is receiving. The battery capacity is great; I’ve managed to keep my phone charged for almost a week just with this power bank (though I don’t use it heavily).It’s perfect for long trips where you need to charge multiple devices. I just wish it had more USB-A ports (the regular USB type) instead of mostly USB-C. Still, if you plan on charging high-performance laptops or multiple devices, this is a strong choice.

If you want to charge a laptop from 0% back to full, this will do it. If you want to charge multiple phones, this will do it. If you want to keep your laptop on all day without running on battery saver mode, you'll probably want a full wall charger.This isn't small by any means, but it's only a bit larger than some laptop power bricks built into the charging cable, so most people will probably have space to store it. I've attached a photo with both a ruler and coins for scale. The perspective is a bit wonky, but it's about 6 quarters long, and 3 dimes thick in both width and height.The speed is what's advertised, although it'll sometimes charge slower for the health of your device's battery, which is common across power banks, and is good for your device's longevity overall. I prefer that to a power bank that just throws as much charge as it can at your device, and I think you probably should too.It's not cheap, but it's not overpriced for what it is. The little screen is great for letting you know how much battery life it has left, how fast it's charging (or charging your devices), etc. It also comes with a nice little pouch to help keep it clean when you're traveling. Not something I need since my bag already has a good fabric lining, but it could be useful to you.

This thing is a beast. Charges my MacBook Pro, iPhone, and iPad all at once — and fast. The screen is super helpful to see how much juice is left and how fast it’s charging. A bit heavy, but worth it for the power and reliability. Perfect for travel or long work days. Highly recommend if you need serious backup power.

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.
