I've had this power bank for about a year and it works perfectly. Great to charge a laptop on the go.
I never had one for the laptop. How many times you can charge a laptop with this charger? Just curious.
Not sure what you're asking here.

This is a 25,000mAh battery, and it looks like you get about 80% after heat and other losses. So if that is the case, it would supply about 20,000mAhs to devices. Laptops have between 5,000mAh and 10,000mAh batteries, depending on the model, so this can FULLY charge a laptop from 0% to 100% about twice.
I use mine when traveling in my car, finding it much more convenient than being teathered to a charger attached to the car. I will usually also just charge the power bank from the car, and operate the laptop at that time with it's internal battery.
You connect this USB-C power bank into your laptop via USB-C cable? It includes a cable.Not sure what you're asking here.
Ok thanks, I just have never charged a laptop without using the laptop charger itself lol. Makes sense

why don't you just tell the guy that it can only charge your laptop to 50% capacity. Generally it only have enough juice to boost up to 50% of most common laptop battery. So this is just for one of those "emergency" that you need a boost for your laptop to complete an important task.
how do you get 50% capacity for emergency boosts?

This power bank has a capacity of 92 Wh. And as you suggest, reduce that to 80% to account for losses; 73.6 Wh.
Laptops have batteries with up to 100Wh; for example, the laptop on which I'm typing this right now has a battery capacity of 99.9Wh.
A MacBook Pro 16 laptop has a 99.6Wh battery.
So, most laptops will get about 1 full charge or less out of this battery bank.
My laptop, or a MacBook pro, would only be able to charge 74% from this bank.
Now, if you have a small cheap laptop this power bank might go a bit further. For example, the $130 Lenovo chromebook linked below only has a 47Wh battery, so you could charge it 1.5 times. But that's an unusually small battery. I assume most people on here aren't using $130 chromebooks.

I don't know of any laptop that has a battery small enough that this bank could charge it 0-100% twice. Do you know of any laptop with a 36.8Wh battery?
