DC plug for Transcend?

[psteckler]

I'm thinking about getting a Transcend unit for camping this summer. I'll be off-grid completely, and not near a vehicle. The review of the Transcend solar panel are pretty bad, so
that seems like a poor option to get power.

Rather than using their solar panel and batteries, an alternative would be to use a powerbank, like the GoalZero Sherpa 100AC, and use a high-quality solar panel to charge it.'
That unit can provide 20 VDC via USB C, which should be right for the Transcend.

But how to get that power to the Transcend? I wrote the company, and they tell me the input jack is "proprietary" (meaning they want me to buy something from them).
Is the jack really unique? GoalZero has some laptop adapters for the Sherpa, maybe one of them will fit. Does anyone here know if any common DC plugs will fit the Transcend?

I've learned that the jack is a CUI PJ-025, so it should be possible to make a trigger cable from USB C to the appropriate plug.

In case others are looking for ways to power a Transcend for camping or emergency purposes, I've test and confirmed the following works:

- 5.5mm*2.1mm female to 6.0mm Male Connector with needle (from AliExpress - $5):

- An Aili Power Bank 5V-21V output power bank case 6x 18650 Battery Charger holder (from DHGate - $20):

Using 6 3000mHA 18650 batteries, my Transcend ran for about 11 hours - so about one night at 7cm pressure without humidifier.

I used the DC out on the Aili at 15v.

Wish I got two nights out of it, but one is better than nothing.
