Krisdonia AC Outlet Portable Laptop Charger (TSA-Approved) 27000mAh 130W Travel Laptop Power Bank & External Battery Pack for MacBook, Laptop, CPAP, Projector and More

In light of all the talks of the power grid being shut off and the increase of climate disasters, I decided I should get prepared. So I bought this! I love all the different ways you can plug things into it. It holds a lot of power which is great for longer term usage. I'll be taking this off grid camping as well. The case is really nice too! I need to get a solar power charger and see how well that works with this but I can only buy so many things at a time in this economy so that will be a near future purchase and I'll come back to update you all!

This is such a unique portable charger with a built-in AC outlet. I tried it on a laptop, and a few other devices, it seems to work just fine. I can’t speak to the longevity or the long-term capacity of this unit yet, but I like what I see so far. I really like having the easy to read display and the ability to turn it on and off. It also comes with this way better than expected soft case, so I really appreciate that! I would say that if you’re considering this unit, it’s primarily for the AC outlet which is rated at 130w. Both the USB-C and USB-A ports are rated at 3A, so check your laptop as it may not power every model without plugging the AC adapter into it. Krisdonia makes models with higher wattage ports, so check those out too.

The device feels quality made and nice materials. It’s a bit heavier which makes sense from the stated storage capacity however dismal and disappointing the performance. If I plugged something in my phone or computer - it’d only charge it a little before it was out of power. Wayyy less than it claimed. Plus it took so long to charge the power bank - hours and then if you plugged something in it would die in 20 min.Maybe it was a dud but was not worth it and there’s better options out there.

The product came with a nice case. It has a pocket for all other necessary cables. Just use a wall cable to charge and it is ready to use. It is compact to carry for camping, travel, and charging devices. I just tried with laptop and printer, and it worked as expected. I think it is good to have a battery pack with AC plug for an emergency or outdoor use, would recommend to others.

A generally good concept, except for some shortcomings.Everything has a cost, not just in price but in tradeoffs. For anyone with an already heavy computer bag, this additional weight and bulk are going to be noticed immediately. If you want power, you pay for it in several dimensions. There is no free joule.Experience shows that it takes about 4-5 hours to charge a depleted battery pack. That is about twice as long as it will power a typical Thinkpad using the AC outlet, though you can use the AC outlet power while the battery pack is being charged. In one test I completely removed the OEM battery from the Thinkpad and the battery pack successfully powered the computer for 2.5 hours on AC OUT without dropping below the recommended 20 percent minimum charge level. Note that the 20 percent is an industry recommendation but not mentioned by the distributor/manufacturer.For a typical laptop that calls for 19-20 volts DC, a far better design solution would have been a DC OUT at 19 VDC. Some Kristonia power products evidently have this feature. Instead, with this device, you have to use AC OUT to run through your laptop AC/DC converter/adapter, and that involves enormous inefficiencies. You lose energy in the DC=> AC conversion within the battery pack, then again with the AC=>DC conversion at your laptop adapter, and the battery pack then has to run a fan to cools its conversion innards, resulting in not just power losses but a bit of noise that may not be welcome to everyone. That fan appears to stay on when supply AC power out, rather than only operating when the internal components require cooling. Another design shortcoming.The "user manual" is the size of a post-card, with type too small to be read normally.To the device distributor: Redesign this thing for a 19 VDC OUT port, and a set of DC tip/connectors for a versatile range of laptops, and you will have a 5-star winner.Nice points:The power status display is a plus.The carrying case is a nice bit of foofoo.None of the components run hot.The AC/DC external adapter meets US safety standards (though the battery pack unit doesn't)The watt-hours output is clearly marked on the battery pack case to shore up your arguments with the unschooled knuckledraggers at TSASpeaking of TSA, the advertised 99.9 watt-hours would mean this is as powerful a "spare battery" pack as TSA and airlines would normally allow for carry-on.If you know how to press buttons, you should be able to operate in pass-through mode, charging the battery pack from an AC source while also supplying power to the AC and DC out ports.Summary: the product is a limited success, reflecting some unfortunate engineering tradeoffs resulting in inefficient power supply and limited utility of the device.

Item well packaged. Instruction sheet provided that will fit inside of case. Plugged in to charge and took about 2 hrs to fully charge. Charged S25 phone from 45% to full in 30 min. Used with RedMed Air Sense 11 (CPAP) for 7 hours, 27% battery remained in the morning. Will be useful if power ever lost or for travel.

I got this for my Cpap dream station 2 but it didn’t work. Maybe the battery was defective because it wouldn’t even turn on after initial testing. Ended up going with another more expensive option and it works well.
