T570 dont like my Powerbank -> 12V Adapter?

Hi
I have an every expedience Powerbank for my T570 who is rugged and design to recharch with an external Solar Pannel. Prepper Stuff you can say.
The Problem the V dont match 100%. My good old T61 dont care about and work perfectly. My new T570 dont like it that much.
So should I get a 12V Adapter? My Powerbank could Output 12V to.

Get a 200W boost converter. They sell them on eBay and can regulate the output to any voltage given any input voltage. 12 -> 16V is no big deal with one of those.

There is this one: https://www.lenovo.com/at/de/accessorie ... /p/0B47481
So can I use that? I dont know how much Power the Power bank put out via 12V.

What is the default V for a T570? The Voltage from the Power bank is slightly higher.

The T570 should take 20V. That adapter hooked up to your solar array should work just fine given your solar array can give ~80W. Those adapters aren't 100% efficient so given a full 65W usage you would need a bit more. 80W is a safe margin. I'd recommend a 90W adapter for a T570 so 110W for your solar array.
