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

This charger is a lifesaver for anyone on the go. It packs enough power to recharge a laptop and multiple devices simultaneously, with fast-charging ports that minimize downtime. The slim, lightweight design slips easily into a bag, making it perfect for travel or remote work. It is easy to use and is built well being that is metal. It works well and is silent when working.

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.

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.

The Krisdonia 27,000 mAh Power Bank is a high-capacity charger with a powerful 130 W AC outlet is good for laptops, CPAPs. I am using it for my CPAP on camping. It features fast recharging, multiple output ports (including USB-C and QC 3.0), and supports pass-through charging. its compact, portable design comes with carrying case. The LED display is a convenience feature. It’s a reliable, versatile choice for both everyday and travel power needs.

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 media could not be loaded. I bought this for emergency backup power and ended up using it all the time. It charges my laptop, phone, and tablet simultaneously with ease. The 130W output is perfect for high-demand devices, and the battery lasts for hours. Super sturdy build and charges quickly. Highly recommend

I bought this Krisdonia charger for my travels, and it's been a lifesaver. It charges my MacBook and other devices without a problem, and the 27,000mAh battery lasts a long time. Plus, since it's TSA-approved, I can take it in the cabin without worry. Compact, powerful, and reliable. 100% recommended!

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.
