I wish the whole mAh measurement was banned and replaced by something more useful. Not my area of expertise, but perhaps WH (Watt Hours)? Some vendors come up with ridiculously high maH values for tiny batteries that wouldn't seem to be possible, but what you don't know is that they're using a lower voltage cell, which they either hide or don't disclose.

You're absolutely correct that we should all be using Wh for apples to apples comparisons. Most of these power banks are 3.7V nominal voltage, so at least the mAh figures are relatively consistent. Where people get confused is by looking at the mAh figure for their laptop (or some other device that the battery pack is not 3.7V nominal) and assuming a 20,000mAh bank will charge their 5,000mAh laptop battery four times, which isn't true.

Would this work very well as additional power for an Oculus Quest 2. I'd love to get a portable charger that pulls double duty at home with my Oculus and at work on the road for my phone and tablet.

Almost bought this before remembering I don't go anywhere and probably won't for awhile 😂

Personally I'm going to wait awhile until I upgrade my power bank, but does anyone know of one like with with Qi and a stand that also has enough PD for a small laptop?

Is there a better alternative with similar features (Wireless charging, Type C)?

I got one a week ago while was looking for a wireless power bank, it was on sale for cheaper price ($33.11). Very solid build and stands work as intended. Wireless charge well at reasonable pace (~10w). I like that it was number indicator that shows the battery level. Can't wait to use this outside of home. =D

I got it last week at that price too. I tried to post a deal on it but it got rejected because it was sold by a third party seller (JIUBILL), so I just posted a message on the thread for the 10000 mAh version here. I guess this policy is to prevent users from shilling which is good. But SD puts through/shills third party deals themselves - even this one is still technically sold by a third party seller (Aukey Direct).

Are there any battery packs that you can charge wirelessly? So far I've only seen wireless charging as output

myCharge made one.

Nope. MBPro will need more wattage thsn 18. Google the amount of wattage you charger puts out or read it on the charger irself. That'll let you know what to look for.

In for one! It took a few times for all of the discounts to work.

Wouldn't a power bank have variable Wh, depending on the device it is charging and the voltage that device supports?

No, the wattage (either in or out) could vary, but the Wh will not vary, as that is the maximum capacity. Very simple to figure out Wh from mAh, as long as you know the battery's nominal voltage (most are 3.7V), just multiply mAh/Ah by voltage. (i.e. 10,000 mAh=10 Ah x 3.7V = 37Wh)

Probably still not as much heat as the i9 processors in current MacBook Pros 😂😂😂

If a CPU uses 40 watts
Then you would produce about
40 watts of heat
How many CPU cycles you get per second per watt
That is what determines parameters
Like speed and efficiency

Don't forget about power loss from conversion from battery or outlet
And the display, WiFi, Bluetooth, hard drive
That's a lot more heat
Charging heat too

Like when using lighting for growing things or shooting movies
1000watts gets you about 1000 watts of light
And heat
