LaserPeckerPowerpack Plus, Portable Charger 23550mAh Huge Capacity External Battery Pack, 3 Output High Speed Charging Power Bank Compatible with All LP Machines

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.

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!

Wasted my money not worth it

Living in the south we are always cautious when hurricane season hits. While we live in the likely safest middle ground of the state of Florida from these storms, there are many occasions where we have not been so lucky and have received a direct hit.We watch the weather and tracking of these storms carefully and we prepare. We never leave an opportunity behind where we can pick up another backup battery charger. And this one is exceptional in how much it can charge. I was able to charge my Mac Air from nothing to fully charged in a little more than an hour and this battery backup still had juice. In fact, the indicator only dropped 1 lights of the four it has to indicate how much charge it has left.It has a USB-A and a USB-C port. The USB-C is input and output, meaning you plugin a cable in the slot for charging the battery itself and you can use that port to charge a device from the battery.I left the battery charger to charge overnight and it was fully charged by morning. We keep all our batteries charged up during hurricane season so we be assured of having our devices as needed as the electricity is one of the first utilities to go during a storm.This battery backup is going to be on the frontline with me for my storm prep from here out. This is a hefty little charger and it comes with a nice case. Easy to charge, easy to charge from, and easy to use. The perfect battery backup charger for all your needs in my opinion!Highly recommended!

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.

This battery is not for charging a phone , this is designed to power same brand laser machines like Laserpecker 2,3 and 4.I own Laserpecker 4 and owned Laserpecker 2 and both operate using this battery for at least 3 hours.This battery has a unique and niche use where it can be used to laser engrave items for customers on the go, like a flee market or street venders. It is a solid product like all other Laserpecker products and I highly recommend it

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 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.
