LaserPecker PowerPack Plus For All LaserPecker Engravers

I purchased as a back up power supply. It works well at rapidly charging mobile devices. I did not purchase it to power the LaserPecker devices.
Unfortunately I have not been able to figure out how to get it to work with my laptop as a back up charge source.
The weight is substantial and for me, the weight alone is why I do not use for travel. This size is great and the travel case is nice.
If one wanted to use for travel it would be a great option.
I like this charging power pack.

So, this power pack is intended for the LaserPecker (only slight judgement for the name of their company) line of laser engravers. I'm sure it works great for those... though I'm not sure why you need to do laser engraving on the go.

For any other type of USB powered device, this thing is bonkers! It will power it forever and ever and ever, until it doesn't, but I haven't figured out when that is.

It isn't light, though it is portable (if you are strong). It even comes with a carrying strap.

My hope was to figure out how to connect it to a solar panel. I have not been able to figure that out and am beginning to doubt it will ever happen.

Great product!

So this product isn't exactly meant for "normal" power backup use. It's actually meant for laser engravers. I, however, don't have a laser engraver, so I'm using it for "alternative" purposes. It's not at all portable - it simply weighs too much to put in a backpack and take with me, but during a recent power outage, I was able to use it to power a handheld gaming console and a Surface for an absurdly long period of time, and could have gone much longer.

I think of this as more of a UPS than a charger. To that end, this thing is a miracle.

I'm not going to lie to you, person who I've never met before, I honestly didn't think this thing was going to work that well. These things never seem to hold as much charge as they say, they never seem to charge your device fast enough. Dude, I was wrong! This thing held way more charge than I'd expected, to the tune of barely having to recharge it while we were on the trip! And the, the fact that it didn't just charge her phone quickly (it always seems to go fast), but ramped up my iPad really quickly too - that thing never seems to charge well unless it's on an outlet. Yep, good purchase. I'm taking this on all my business trips. When not traveling I used it for my engraver and it worked really well and let me work in a more comfortable area, not attached to the wall. This thing is amazing with how much power it holds.

The battery is surprisingly compact compared to others that I have for the capacity, and is very easy to store in almost any backpack or bag. It’s about the size of an IPhone 15 pro max in height and width etc, just square of course. Easy to charge with usbc and to discharge as well. Others complaining about price I feel are misguided. The other battery I got some time ago was about the same price but was a greater capacity and had more ports but was much larger, didn’t support usb c, and I’m pretty sure was nickel iron instead of lithium ion like this is. This is a high end battery and looks like one was well. Well designed and works to charge anything usbc will. I think for the price is is more than fair. I would strongly recommend it as a backup to carry with you to class or school or even to work. For I work remote and have class, sometime forgetting to charge my devices. But, with this charged at least, I’m able to charge all my devices and keep them such for hours. And the compact nature of it is a major reason for me.
