Aldi currently have the A3 light pads in stock at $40 (near enough).
On smaller telescopes these are great for doing light frames and a lot of people have used them for this purpose. You can tilt the telescope skyward and sit the light board on top and smaller telescopes and camera rigs you can simply stand them directly on the light pad indoors to get good even lighting for light frames. Easier and I've found them to be more uniform lighting than a t-shirt and torch.
The unit comes with a 220V power supply with USB-C cable connected. To use externally a standard portable power bank with a USB-C cable (not supplied) will work fine and the latest iteration appears to be better made than the much older identical branded item I already own. The unit has no internal batteries.
I did see mention from a fellow member they weren't so good on larger telescopes, maybe faster f units, I don't remember but the things work fine up to my 8" Newt and RC. They may fit on a 10" tube I don't have a 10" telescope to try.
