I have this same device and its ok. I spent closer to list price a year or so ago. I was really excited to use the PD power to charge my work devices, there seems to be a lot lost in the transfer/voltage though.

I have a surface pro 6 (and a cable that goes USB C to the Surface connector) and a Dell XPS 15 (native USB C charging)

The battery pack is 20k mAH. The Surface Pro 6 has a 6,000mAH battery or so and the XPS has a much larger battery (i have the 97whr, looks to be about 8,500mAH).

I was hoping to get multiple full charges from battery pack. On both devices it will charge the devices and run it for about 2 hours, and that's about all before its drained. My devices do pick up 30-50% battery charge too, but in my mind i was expecting 20,000 mah / 6000 mah (for SP6) i was hoping to get 3 full charges on it.

I complained to RAVPower and they said nothing, a few weeks later a new battery showed up without a return label, so i now have 2. I tested and it does the same thing. I dont think it was a flaw in their devices, just how it works though. If you have a fancy new device that can charge with power delivery, this will do it, just have proper expectations.

I have a different brand battery, don't know the brand right now, maybe zero lemon, but it's 45 watts pd 20000mah, but I have a very similar experience with my XPS.

My laptop has a decently sized battery 7680mah and can only get less than one charge using a 20100 mah battery pack (Zendure battery pack). The only one that gets me more than one is a 26800mah by Luxtude (sold out on Amazon it seems) and I can get like 1 1/2 to 1/3/4. Needless to say, very disappointing.

If someone can post a power bank that is true to its advertised rate, would be great.

In any case, I would aim for the 26800mah market if you want more than one full charge.

edit, luxtude still being sold https://www.amazon.com/Luxtude-Po...160&sr=8-4

I got it in a lightning deal for $61 and would NOT pay $89 for it. But positive reviews are legit, gets an "A" on fakespot...

one reviewer provides the "true capacity" of the luxtude, which is consistent with my results:

This power bank is one of the best in the market in term of charging the power bank, my doubt is about the advertised capacity. I did a test using a USB C Power Meter Tester, an Eversame USB Voltmeter Ammeter Load Tester, and a DZS Elec Mini USB 0.15A-3A Electronic Load Tester. results are shown in the pictures.
Pro: fully charge in less than 4 hours
Con: advertised capacity is not accurate
with PD USB C, its only output capacity of 14650mah
USB-A its only output capacity of 16444mah
All of this was done with a 5v and 3A testing

Usually you need to multiply by .8 to get the chargeable capacity as there will be conversion losses. Considering this is rated at 20k, the 16k you got with USB A charging seems right.. (20k * .8 = 16k)
