4 solid lights: 76% – 100%
3 solid lights: 51% – 75%
2 solid lights: 26% – 50%
1 solid light: 10% – 25%
Blinking light: Under 10% (Needs to be recharged immediately)

These are TSA approved for carry-on. Also, I use this exact one in a paper mill (120 degrees plus in the summer, high humidity all year) with no major issues. The ONLY thing I've had it do is drop from 12% to 0% within minutes when it gets hot. But, in such a work environment, I figure I have a bad cell. Still able to charge an S20 and earbuds for 3 full days before I have to recharge it.

Community Reviews

Anker's 24,000mAh 537 PowerCore stands out as a high capacity travel battery that can keep laptops, phones, and earbuds going for long stretches. It is described as reliable over years of use, with enough output to fully charge a 16 inch Galaxy Book 4 and still leave battery in reserve. The main drawbacks are its bulk, slow recharge time, and the lack of a digital percentage display or pass through charging. A few comments also question the advertised 65W output and note airline carry on limits for large batteries.

Common Questions (5)

  • It can deliver 65W on a single charge, but output reportedly drops to 45W and 20W when charging two devices at once. That makes it suitable for a laptop that needs up to 65W, but less ideal if you expect full power on multiple ports simultaneously.

    makimbellnhatChpByr

  • It can charge laptops, including a 16-inch Galaxy Book 4 fully with about 40% left afterward. A Dell XPS 15 9520 may also work if it accepts third-party charging at 65W to 90W, but that depends on the laptop's power limits.

    FuschiaDeer1674liqwicked

  • It is described as TSA-approved for carry-on, but large 24,000mAh batteries can still be rejected by some airlines or at some airports. That means it may be fine for many trips, but airline-specific rules can still block it.

    CrimsonScent3556faheyd

  • No digital percentage display is reported. Instead, it uses four LED indicators: 4 solid lights for 76%-100%, 3 for 51%-75%, 2 for 26%-50%, 1 for 10%-25%, and a blinking light for under 10%.

    CoralDolphin3328desynergy

  • No pass-through charging is reported, so it cannot charge a device while the power bank itself is being recharged. That matters if you want to top up the bank overnight and still use it as a charger at the same time.

Your airline doesn't have a website with all of the pertinent information available? 🤷 ♂️ Even Spirit Airlines had such information readily available, may they RIP…
I use to curse Spirit when they were around because I hated their seats and the overall experience of their service and flights. After they bankrupted, I can honestly say I didnt know how good I had it. Paying more than double for my flights now, I look back at the days I took Spirit and understand that I took them for granted lmao rip. I never thought I'd see the day that I would say I miss Spirit but I truly do.

I'm sure this is good quality, but it bugs me that it says 65W output when actually it's 45W and 20W
Yeah, Anker loves to misrepresent the wattage of their chargers.

I bought a "140W" Anker charger that was actually a 100W charger.

If 20 watts is sufficient, here's a 20,000 mah battery for $20.

Ironically, it IS 65w on single charge & 45/20 on double, but on amazon this thing has an amazing (for Anker) 20% one star reviews.

Oddly I never had a bad Spirit experience. I'm tall so did always upgrade to the big seats, and those were comfy at least. The crews were fun too!

common people, GO to amazon and look for this product to be a slick dealer. You will see a number of anker products like this, some with more power, or some with screens too. That is all I will say. After researching, buy if you think it is good deal. I am just saying I'm not buying it.
TD, pretty pedantic and unhelpful comment.

Can you charge the dell xp 15 9520 with this? Have an anker 737 and it has the same 24000 mah and has max 140w total output. The thing is because dell laptops recognize 3rd party power banks as 3rd party, the max draw is 65w to 90w only.

The thing is if it can it's basically the same as the anker 737? Or is this mainly for phones and ipads? However, 24,000 mah is a lot for those type of device.

Researching was all I recommended. I think a good slick dealer should research something they are planning to buy.So you gave me a thumbs down for my post, for recommending research? I am not going to give you a thumbs down, because you had valid point, too.I hardly EVER use the thumbs down for individual posts, because each person is just giving their viewpoint, and their experience. I love other viewpoints, don't you?

Just received mine. CLEARLY a used product, so who knows why it was returned and how much longer it will last.

Edit: apparently mine was the deal with the extra 10% off, but it's the same product.

Seems like Amazon has been doing that a lot lately -- sending used/open box items when a customer orders new. It's happened to me twice in the last few months, whereas I never had an incident in the last 15+ years.

Thanks, I bought two! With Prime Day so close, I was thinking there could be better deals on banks, but Prime Days often aren't very good in my experience. This is a safe slick deal since it's Anker.
