Not entirely sure that pertains to what you were seeing, but hopefully it helps!
It's labeled for ≥ 75% efficiency and ≥ 37 Wh, so it's either < 72% efficiency or < 37 Wh, either of which violates the text on the unit itself. I'm charging it back up now to see if we can wheedle out which it is, but this isn't a great first impression and I'm probably returning it.
edit: charging it back up at 5V@2A cost 39.3 Wh. I got 31.6 Wh discharging at [email protected]. So it seems like the efficiency is just bad.
edit 2025-03-01: this thing is just trash now. I don't know why I didn't return it. I can barely get half of these numbers out of it now.

Once power bank fully charged. It charged Samsung S10 as 'fast charging' via Type-C port from less than 10% to above 90% around same time if used Samsung-fast-charger wall-outlet. I was able to do 2-full charges from less than 10% to ~95% and 3rd cycle was till 75% charging then power-bank ran out of juice.
2 and half times charging for Samsung S10. Fast-charging only works through Type-C port only. This port is Input/Output both for this brand. $13 it is a deal for 'fast charging'.
It's marketed to quick charge at up to 18w for PD equipped devices. It does that for me via USB-C. Based on the amount of recharge I've gotten out of it, the capacity seems accurate as well. Could you get one with 2 USB-C ports in place of a silly Micro USB? Sure. Could you spend 4x and save an ounce or 2 on a Nitecore charger? Sure. None of that is a criticism of the power bank though. What is marketed is accurate. Many of the complaints are due to people not paying attention to what they're buying.

I have used them travelling overseas multiple times now.
I am actually in Italy right this moment with a Baseus power strip charging my 2 Baseus power banks. One is a 20,000 mah with a built in usb-c cable. The other is just a plain power bank, 20,000 mah, no built-in cable. The built-in usb-c cable is awesome. No need to find both a power bank and a cable, just plug-n-go. Also the cable is very durable. It hasn't broke yet and I'm not gentle with cables at all. I've gone through numerous Anker cables to the point that I don't even bother to pay up for Anker. I break Anker usb-c cables way too often to be paying the premium for them.
Just to prove that I'm not a shill for Baseus or some uninformed keyboard warrior sprouting off at the mouth, here's some real-world feedback:
I do have some small niggles with the power banks. It's almost as if they have slightly buggy software installed on them. One of them refuses to charge my (very low wattage) wireless earbuds (JBL Go Pop). The earbuds only need 1 watt (5 volts, 0.2 amps). One of the Baseus banks appears to be unable to detect such a low charging wattage requirement and doesn't want to charge the earbuds. The other one can be forced to charge it by resetting the power bank (holding down the power button). Not really an issue, and from what I understand this is actually a fairly common issue across all power bank brands--difficulty detecting and charging devices with very low power needs. One of them also doesn't like to play nice with my Spigen GAN fast charger, but the other one will. Both power banks work flawlessly with the Baseus branded power strip, though. The wireless earbuds also charge w/o a hitch using the black (not orange) USB-A port on the Baseus power strip.
The other nice thing about Baseus power banks (at least their larger 20,000 mah ones) is that they support PPS aka programmable power supply, which is a must if you want to "fast" charge a Samsung. Samsung's charge fairly slowly and my Baseus power bank with the built-in orange usb-c cable can hit 9.9 volts at 4.6 amps while charging my S23 Ultra. The other one can go up to 10 volts or so at 4.2 amps. I needed a power bank with PPS and not just any old PPS but higher-amperage PPS and Baseus was essentially the only affordable option with >3 amp PPS.
Not entirely sure that pertains to what you were seeing, but hopefully it helps!
I just went ahead and ordered another one. The 35% coupon worked again.
I will stop buying them now.
I do NOT need all of the Baseuses to belong to me.

RFI not too bad if you keep it away from your antenna.
No idea how long the battery will hold up, but for the price I think it is decent.
