Can this Power Bank power a 30W led lamp for camera?

[FoxAdriano]

Good morning, can you please tell me if this Power Bank can power (turn on) a 30 watt led lamp for camera?

The led lamp is this:

If it can't do it, can you recommend a travel one?
1000 Thanks

The Power Bank doesn't power the LED lamp directly, but it can charge the lamp battery.

The Power Bank has a 26,800mAh capacity when charged, and the LED lamp has a 4,500mAh capacity battery, so it would appear you could charge the lamp 4-5 times from a charged Power Bank.

I thank you for your info.
But I like to do an example:
when the battery of the lamp is almost empty and after 5 minutes it doesn't work anymore, if I connect the Power Bank, will it make the lamp work for a long time?I don't understand this. A friend told me to buy a power point with PD. Can you explain it to me better please? I don't want to charge the battery of the lamp, but I want the light to last longer.
Therefore what do I have to do?
Thanks agin.

No; that power bank is not a "PD" type, it's only 5V output.

"PD" (Power Delivery) types can switch the output voltage to different levels if the device being charged needs that: 9V, 15V or 20V usually, in addition to the standard 5V.

The light may work OK with a 65W or greater PD rated power bank - look for ones that mention charging laptops with them.

Just as an example:

https://www.amazon.co.uk/UGREEN-25000mAh-Portable-Charging-Compatible/dp/B0CXHM5RY2/ref=sr_1_38?

The light info does not seem to say what voltage & current it needs from the PD charger, so it's not possible to be sure of anything.

Thanks for your precious news.
Can you satisfy my curiosity please? If I wanted to recharge a battery like this:
16Wh 7.2v 2200mAh which has its own specific charger that is not PD and has a USB3 cable, if I connect its charger to the high power Power Bank like this:

https://www.amazon.it/CUKTECH-Caricatore-Portatile-Caricabatterie-MacBookPro/dp/B0DNQVVVJT?pd_rd_w=NYw2n&content-id=amzn1.sym.20f14dbc-9d8b-409d-bf63-222378c8d3f2&pf_rd_p=20f14dbc-9d8b-409d-bf63-222378c8d3f2&pf_rd_r=E4SBESE61KBNWWQER0YE&pd_rd_wg=4Lond&pd_rd_r=a7a8fffe-5c2a-460e-8649-e0d39fca7795&pd_rd_i=B0DNQVVVJT

What's going on? The battery is charged but it gets ruined and then I have to throw it in the garbage? Or could I charge it a few times and be calm?
Since the cost of a good Power Bank is quite high, I would like to charge any type of battery, even those with chargers without PD.

A non-PD one connected to an output on a PD one should charge fine.

The only thing to avoid is connecting two power banks by USB C at both ends, as there is nothing to show which is the one providing power to the other.

As long as the one being charged is connected via a USB A socket (standard rectangular USB) on the one providing power, any should work. USB A sockets are output-only, while USB C are input or output.

(A charger or power bank with PD output will work like a normal 5V charger until it's connected to a device that works with PD, and that tells the charger to use a higher voltage).

First of all, thank you for the valuable information.... and for your patience! I'm learning more and more. But maybe I didn't understand well what you described to me. I would like to be clearer with an example with a PD Power Bank. I would like to buy this one that has a voltage of 20v:

I would like to connect that PD Power Bank to this NON PD charger to charge the batteries of a camera.
I attach the specs in the photo.
The charger is it:



The voltage to recharge the battery is very different.
Can I charge the battery or will I ruin everything?
Thanks again.

(A charger or power bank with PD output will work like a normal 5V charger until it's connected to a device that works with PD, and that tells the charger to use a higher voltage).

A quick comment that may be disregarded in the current conversation but should be noted:

A USB-C PD charger connected to a non-PD device with a USB-C connector might not provide 5 volts to the device. Some devices don't include the required pull-down resistors on the CC pins signaling it's a 5 volt device, so the PD supply may simply ignore it (i.e., will provide no power).

I had had this occur on a number of different micro breakout boards, with other devices and with USB-C connector designed to deliver only power.

Using a USB-A to USB-C cable will solve this design issue.

In the example I just gave, shouldn't they have the same voltage both the charger and the Power Bank??

It shows 5V as one of the input power options, so presumably it uses a USB cable?

As I mentioned use a USB "A" socket output on the power bank and that will be 5V so fine.

 

[FoxAdriano]

It seems incredible ... but wowww, thanks so much.

EDIT: even if USB-C works, is it better with it or is it always better using USB "A"?
