tl;dr: The Wh rating provided on power banks is agnostic of the voltage and would be a better "apples to apple" comparison of power bank capacity than mAh ratings. Wireless charging is inefficient and compared to wired loses 25-50% capacity due to losses.
The details:
Specified mAh capacity refers how much power can be delivered at a certain current over the time that the battery has power. If this is not specified with a particular voltage is, it's referring to the voltage of the battery cells inside the power bank, which is why they specify at 3.6 V.
The voltage can be upconverted to a "standard" USB 5V but that reduces the mAh rating proportionally . I've looked at my Anker/Ravpower/Belkin/Inui/Baseus banks and they all specify at 3.6 V. Sometimes the conversion to 5V is also given but not usually.
Wh capacity of a battery pack takes the voltage into account, and is a "clearer" representation of power capacity.
As a second issue - wireless charging is intrinsically much less efficient than wired charging (even when wired, a "3000 mAh battery pack" may need 4000 mAh to charge it), and at best case scenario wireless charging only delivers 3/4 (compared to wired charging) of the power capacity to the charged unit, with the remain lost to heat and other conversion inefficiencies. Realistically with wireless charging even in best case scenarios a 3000 mAh phone battery may only be half charged by a 3000mAh power bank.
At worse (poor alignment, greater separation) it could be less than half of this.

This ultra slim Qi2 MagSafe power bank stands out for pocketable, cable free top ups on the go, especially with Samsung Galaxy and Pixel phones in MagSafe cases or an iPhone snapped on for travel. The slim shape and light feel make it easy to carry in a purse, backpack, or pocket, and the build quality and price are described as solid. The main caveat is capacity and consistency, since the pack is effectively around 3000mAh after conversion losses and wireless charging, so it may only add a partial charge. Fit and charging behavior also vary by phone and case, with some setups disconnecting or failing to align well.
The power bank can snap to the back of a Samsung Galaxy S23 and charge without cables.
The power bank can work with a MagSafe case on Samsung S24 Ultra for on-the-go charging.
The deal can be improved by stacking a 5% off page coupon across multiple items.
The promo code can eventually apply correctly after retrying in different browser modes and refreshing.
Wireless charging can disconnect or reconnect frequently on some iPhone models and cases.
The advertised 5000mAh capacity can translate to an effective usable capacity closer to about 3000mAh due to conversion losses.
Wireless charging performance can be poor on certain Samsung devices when Qi2 coil placement mismatches.
The power bank can lose charge when left unused and can take a long time to recharge.
