Amazing device. Holds a good charge for a long time and charges all necessary items. Will even charge a laptop.

The Krisdonia AC Outlet Portable Laptop Charger just become my new favorite travel companion. It super Convenient for TravelThis power bank is TSA-approved, so I’ve taken it through airport security without any issues. It’s compact enough to slide into a backpack, yet powerful enough to charge my laptop, phone, and even a mini projector when I’m on the road. It’s a bit heavy: At around 2.6 lbs, it’s not featherlight. You’ll notice the weight if you’re packing light, but personally, I think the power it provides is worth it.I’d definitely recommend it!

Had to use it with my cpap for the first time last night. Had it charged to 100%, shut off my humidifier and the heated hose and it ran for about 4.5 hours.

Packs a lot of battery capacity to charge my devices, and most everyday gadgets we commonly carry today. It has a 3-prong charger port to charge a wide range of devices that can’t be charged via USB, but it also arrived with an international adapter for use outside the USA.

Works like a charm and perfect for travel and charges my devices quickly giving me additional charging for my laptop when I can't access an outlet. I can see this being useful for power outages or emergencies and needing to charge multiple devices at once.

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.

I have been using this for a month. It is not that heavy and the 130W output and AC outlet make it incredibly versatile — I’ve used it to charge my MacBook, phone, and even a small projector without any issues.The charging ability is very quick.The 27000mAh capacity is impressive and lasts a long time. I love the digital display showing exact battery percentage — it adds precision and convenience. The layout of the ports is thoughtful, and everything is clearly labeled.Design-wise, it’s sleek, compact, and feels very durable. It fits easily into my backpack, and the matte finish gives it a premium feel. The TSA approval is a big bonus for frequent flyers. It is a multifunctional device.
