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.
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:
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 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.
