It will not surprise you, but hands down the Cuktech 15 Ultra - by far. You want rapid Charging? Almost Nothing beats the Cuktech in this regard. 140W Input for 42 minutes or even dual-port Charging with 165W input for 35 minutes for a full charge.The Cuktech 15 Ultra is one of not many 140W powerba

Really have an eye on Cuktech. They have some of the best on the market. Their Cuktech 10 is the most powerful and overall great 10k on the market with sustained 100W performance, 120W HyperCharge and also great PPS-Range. Their Cuktech 15 Ultra is still the best 20k on the market. The Cuktech 300W

I am facing the exact same problem! The pi is really a pain because of the strange PD requirement. I want to be able to power my deck with a rechargeable usb power bank and I don't want to use a dedicated UPS hat with integrated 18650 cells. My current plan is to use a cuktech 15 ultra power bank, b

Mein Tipp aus vielen Reisen: Nimm eine die sich sehr schnell aufladen lässt. Mein Tipp: Anker 737 oder Cuktech 15 Ultra. Laden beide mit 140w Ladegerät in unter einer Stunde voll. So kannst du mittags im Cafe das kurz anstecken und hast wieder Strom für mehrere Tage. Das ist ein riesiger Unterschied

For a rental car, this is the setup that works best for me: Power: a CUKTECH 15 Ultra power bank. It feeds the Starlink Mini beautifully, and because it runs in true UPS mode there are no voltage gaps, the dish never drops or reboots. At the same time, when the car is running and powering the cigare

If you do go for the Mini, here's the in-car setup I'd run: Power: a CUKTECH 15 Ultra power bank. It runs the Starlink Mini with no dropouts, because it works in true UPS mode, the dish keeps a steady voltage and never reboots when the car turns on or off. And while you're driving, if the bank is pl

Since the TSA side is already covered (keep it under 100 Wh and you're fine with no approval; 100 to 160 Wh needs the airline's OK, max two packs), here's the part that actually decides if a bank works with the Mini at all. Two numbers matter more than capacity: The boot spike. The Mini pulls a shor

This one would work well, $70 should get you an extra 20000mAH on top this one has generally tested well. https://www.smartzone.de/cuktech-15-ultra-im-test-20-000-mah-powerbank-mit-165w-input/ (DE) https://www.notebookcheck.net/The-beast-among-the-20k-power-banks-Cuktech-15-Ultra-review.1300618.0.ht

Cuktech 15 Ultra. 72Wh 20000mah, 210W MAX output and 165W input to both c port at the same time. It's better to not have power banks that are over 20000mah, Some unprofessional security staffs look at "mah" instead of "wh" and sometimes reject banks with battery <100wh but >20000mah

I have the Cuktech 15 Ultra and I really like it. I think it is better than the 20, though it has a little less capacity. I also have the 737 and feature/performance wise I would prefer it over the Cuktech 20. 15 Ultra vs 737 is a hard decision.
