My New Travel MVP!
This thing is awesome. I grabbed it for trips and it has way more power than I expected. The AC outlet is clutch — I can plug in my laptop, charge my phone, even run a little projector. It feels super solid, charges fast, and the display is actually really handy. Honestly just a super reliable power bank that does exactly what you want. Definitely worth it.

Power bank with lot of power
impressed with battery like, I wish it had more USB C ports but at the same time the 110 V outlet just make it compatible with many more things. I was able to charge my laptop couple of times and it still had some juice left.

Battery life is horrible and it takes forever to charge up a laptop only plugged in
I so wanted this to work, but it did not!! Even when fully charged, it barely stayed charged for 2 hours at best. It only charged my laptop and took forever, progressing only 1% at a time. And it is heavy

great power bank with a lot of power
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!

Powerful and Multi purpose Power Bank for on the go uses
Excellent portable power bank for travel and work! The Krisdonia 27000mAh charger handles my MacBook, phone, and even a small projector with ease. The built-in AC outlet is super convenient, and it’s TSA-approved so no hassle at airports. Fast charging, solid build, and long battery life make it a must-have for business trips or outdoor setups. Highly recommend for anyone needing reliable, high-capacity portable power.

Reliable
Very useful for travel and remote work. It charges my laptop fully and still has enough battery left for my phone. The AC outlet is great for small devices. The display is clear and easy to read. It is a bit heavy and takes up space in a backpack. Overall, a reliable backup power source with good capacity.

Useful, but.... suboptimal design, heavy, inefficient, and noisy
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 TSA Speaking 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.

Product came with a nice carrying pouch and pretty good build quality. My primary reason for buying this was to power my ResMed AirMini CPAP machine for overnight camping without access to a power outlet during the night. Out of the box and charged up to 100% battery before first use, the pack powered a full 8 hours of sleep (my pressure is at 8.0) and brought the battery down to 39%. I'd call that a win!

This little box packs a huge punch. I purchased this to run my dad's portable oxygen machine for a cross Canada plane ride. It worked the whole way, got a quick recharge in the Montreal Airport and lasted the whole way. I now plan on keeping in my truck for work/camping and would highly suggest this product to anyone. My family have now bought another one for our other vehicle as well to power the kids' toys

L'emballage du chargeur portable était brisé à son arrivée. Le matériel de l'article n'est pas de qualité et on s'attend à un produit de meilleure qualité pour un chargeur portable à 200$+. Je vous conseille d'opter pour des marques beaucoup plus connues pour éviter ce genre de situation.

Took this on our Safari to Africa and ended up powering up a whole show when we lost power at the safari resort. It was much appreciated by more than our family.

My pack just died, so I thought I'd do a retrospective. TL;DR - With the exception of a capacity-bump to 160Wh, I'd probably still choose the same pack now. I picked this one based on 3 criteria: 1. Capacity: It was just under the FAA 100Wh limit for air travel (this has since been increased to 160Wh for after-market battery packs) 2. Features: passthru power, USB, USBC, and AC out (including a ground prong) 3. The price: It was significantly less than all other packs with the same capacity and features. Work requires me to be operating a laptop while walking around / parked in strange corners of industrial spaces, often without access to facility power, for hours at a time. Outside of work, it's been on countless hikes and climbs. This pack was an absolute lifesaver on nearly every trip it took during its lifespan; working without fail for just over 2 years. 2 years does seem like a premature failure - but I think the lifespan is not-a-dealbreaker for a battery packed used almost daily during that time. Completely reasonable to disagree on that point, but I'm looking forward to purchasing a replacement pack all the same.
