Dell Type-C Charge with Powerbank

[hardusb]

Just checking if anyone came across something like this before or have a solution.

I recently bought an Dell Latitude 7430 laptop which charges with Type-C. With my previous Dell XPS I used a Winx 100w PD Powerbank (https://www.winxstore.com/product/go-ultra-20000mah-pd-100w-power-bank/)
to charge it aswell as my macbook air m1 without a issue.

For some reason the powerbank just flashed the 100% then goes dead, laptop do not pick it up. I used 2 different cables, both able to go up to 100w.

I have 2 x Ugreen 65w wall chargers which works fine on the Latitude.

Just trying to determine if theres another powerbank which will work, Dell has their own version, but its R2500 +/-

Perhaps it's a setting?

Since your new laptop only requires 65W you can get this one, which has double the capacity of your current powerbank:

Charging works with the original Type C Charger and my 2 x Ugreen Wall-Adaptors. I dugg around in the bios and theres no mention of chargers etc.

My Winx Go Powerbank does not charge the laptop, it is rated at 100w. It charged my previous 2 laptops. This dell does not even pick it up. I tried various different type c cables and both ports.

I did some reading up and the dell specs page lists the voltages supported. (Link)

The Powerbank's Specs is correct: (Link)

Is it maybe that the laptop is not negotiating the power but needs a "Fixed" Output?

I saw this online awhile back and was wondering if this would work: (Link).

Yes! This one works on my 130W Dell Precision Thunderbolt. Wish I had more of them.

ZMI PowerPack No20 - 25000mAh/2xUSB-C/1x USB-A/210W PD Power Bank

It's difficult to find a power bank or cable that will work with a Dell Laptop.

I had a writeup on it somewhere here on the forum and why most won't work with a Dell Laptop. Specially the professional laptops.

Here you go. Hope it is somewhat helpful. Might not help finding a power bank but will help understanding why some models might not support any power bank.

Dell Precision 15 / XPS 15 Power Bank

PW7015L seems for the older Dells which use a DC pin(barrel) charger. Ah snap! Stupid me. I wondered what (barrel) meant. Only click now. I will sit with the same problem as @JuliusSeizure then. :ROFL:

Excuse my ignorance but I had a squizz on that thread and couldn't see how that directly related to the op's problem, what's wrong with the Winx Battery bank he's using?

Could be the USB C cable even. I won't know. Dell uses proprietary software that limits power banks and non Dell power sources.

Try swap for another one, if that one does the same then will have to shop till you find one Dell will support.

That's what I would have thought but if the same cable works in conjunction with other USB C charging devices as the op mentions then it would seem that can't be his issue, nevermind that the same setup also worked with other Dell laptops.

Dell also have their own power bank, also on the expensive side: Dell 65Wh 6-Cell USB-C Notebook Power Bank Plus PW7018LC, but noone has stock, must be a reason for that.

I would have thought with the Type C charging Dell would have stopped with their compatibility issues and proprietary chargers.

some chargers require the 2 data wires to be bridged to put out max capacity ,if not the psu will only output say 500 ma ,the data wires on some units tell the psu how to charge so by bridging them its balls to the wall full power .dell may not tell the charger what to do or it may not use the 2 data wires ,so the psu bank gets confused and limits itself .
