I bought this with the same price last 4/1/2025. It seems to be a great power bank.

While this is cheap, it is relatively large and very slow speed, it will take 4 hours or so to fully charge it. The 20000mah 65 watt model is a much better buy and it was down to $23 a couple weeks ago.

I got this one a couple of weeks ago. Sadly, charges my phones very slow, and I doubt its really a 20000mAh capacity charger.
Charging a Pixel 6a from 5% to 100% leaves the charger at 50% remaining battery.

I wouldn't purchase it again and I cant recommend it.

Very slick price IMO. I have this and used it on several trips. Charges my Pixel 9 fairly quickly while in constant use.

If you don't already know, you may want to learn about "efficiency" it wouldn't be that surprising that a 20,000mah charger would put out almost 5000, and be down 50%. while they hold 20,000, they are inefficient and don't put out 20,000 for the receiving device to take up. So you can't "fill up" a 5,000mah device 4 times from a 20,000 mah charger. This one could be particularly inefficient as you note.

i'm doubtful because its alot smaller than a fairly new anker 20000mAh that i have.. so is the anker one just using older batteries / inefficient design? the most likely answer is this one is lying in my opinion

And they could be lying! But efficiency of 50% isn't unheard of.

I'm just sharing my experience with this specific charger. My Samsung and Anker 10.000mAh chargers, both charge my pixel twice before running out of juice.
Honestly, at $12, buy it if you need/want it, won't hurt anyone's wallet.
I don't have anything against this brand, in fact, I have and use their wall charger and some USB cables I got on sale as well, lol.

20000 mah probably won't be under 1 inch thick. If you want something pocketable search for 10000 mah.

No worries, unsure if folks understood efficiency, and 5k could be 35-50% of 20k depending on temperature, if the phone was off, etc. Also this brand could certainly be either lying, highly inefficient or both!
