Rechargeable powerpack for HP laptop

frisket

I have a HP Envy 17" laptop and I need a powerpack (powerbrick) that will recharge it (preferably twice) so that I can work in a location with no mains power.

The mains charger has a 90W rating, and the internal battery is rated 55Whr. Has anyone suggestions for a suitable powerpack, or warnings, etc?

Dell make powerpacks for their laptops, but HP don't, and although the Dell plug fits, sadly the Dell ones don't charge HP kit (some smarts in the connection obviously talk to the laptop to ensure it's a Dell).

What's the mAh? Most laptops would be 4000 - 6000 mAh.

Something like this should charge it 3 times over anyway

I don't know where to find that but I think it's 6600 mAh.

That certainly looks interesting, thanks very much. It does say "【NOTE: PD charger is NOT included, please use a DC/AC/Wall charger supporting PD protocol, otherwise the power bank cannot be recharged】" so I'll need to find that if the HP charger that came with the laptop won't do it, because that charger has a Euro plug on the end, not a USB-C. And it doesn't come with tips, so I'll need to source a USB-to-Euro of the right polarity (which means finding out what the right polarity is).

I ended up buying a Krisdonia 25,000mAh power bank. Recharges in about an hour, holds enough to give a full charge to my greedy HP Envy laptop. Can deliver different voltages, and has two USB outlets as well as the DC one for laptops, and comes with a vast selection of plugtips so it should recharge pretty much anything.
