Not a fan of built-in cables (but retractable is nice) however if it fails there are still ports that support up to 100w. I've had a couple failures from this company over the last few years but as long as the failures are within the warranty length (2 yrs here) they are very easy to work with over email for refunds/replacements. If you need a 100w(+) battery this is a pretty good deal for a product with a solid warranty policy. TU

Is this TSA compliant? What does "up to 145w" mean?

I've got x2 of these and they are the highlight of a travel kit. I know other people don't dig the built-in cable but this pack gets far more use than the ones that don't retract and I find it super handy to not have to carry another cable around.

Great buy. Only minor gripe is that the display is very dim.

You will want to verify but it should be FAA compliant. I believe the threshold is 27K for battery size (this is 20K). 145W is the max power delivered. You want high power delivery if you are charging a laptop.

Suspiciously small for 20,000mah. One review says the actual device says 5000mah on it.
I have two of them they are 20k - same size as other 20ks

These have 4 of the large blue batteries, the same as what the Tesla car battery packs use. I have the UGREEN version of this. I am in the Philippines. These cost around 900 - 1200 peso on sale, or around $15 USD. You guys are getting ganked over there in the USA. You want to look for the 100watt IN/OUT ... the 145watt is if all the ports are being used at the same time.

I want to educated you guys. This design, the footprint holds 4 x 18650 lithium-ion cells. The 20,000 is marketting bull$hit. Each of those 18650 cells top out around 3500mAh of capacity @ 3.7, or around 14,000. The Chinese and everyone else love inflating numbers. They do it with cheap stereo equipment. The airlines know this. With that said, this is the design footprint you want to look for since it still gives you enough juice to recharge a phone 2 or 3 times, or a laptop @ 100watts up to 50% or so. I have a couple of these and as long as you get one that is 65 - 100watt IN/OUT, you will be good to go.

what are you trying to do? Just have a small portable battery bank for your car to take with you incase? I guessing not since you can use a car solution for that. So something for your home?

Mostly just for traveling. Apparently the one in the car doesn't work, but I need to look into it. But it would be nice to have one for traveling without a car.

Because of frequent incidents in carry-on bags, some countries (like Korea) are very strict about not having batteries exceeding 100Wh. FAA is more lax and limits no more than 2 batteries in the 100-160Wh range. So this battery could be problematic if you travel internationally.

18650 cells are about 2.5" long. Considering small size and weight is a desirable feature of these, there's no reason to make a powerbank with these dimensions with only 4 cells if you're willing to lie about specs.

Pretty clearly 6-8 cells in this, which put it right around claimed capacity specs.

That being said, there's still issues with these. Most of the cheaper "145w" chargers have garbage thermals and while they can reach that output, they can't sustain it for a long period. Baseus batteries pretty consistently have that complaint in reviews.

And then there's the common complaint that it's 145w aggregated output, where it maxes out at 100w+45w across two outputs, and can't do single 145w output. But that's been an issue with power bank marketing since forever.
