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

Volessence portable battery seems like a good option for those who need a relatively compact (considering the capacity and the features) source of emergency power. It's heavy due to its capacity, sturdy metal frame and the inclusion of an AC inverter and outlet, but that's expected given its specs.Pros:Can charge your laptop fast (with AC output).Can run full-sized CPAP machines without stuttering (though not with humidifier and heated tubing)TSA-approved (based on the mAh capacity, do your own research before travel)Multiple outlets (USB A, USB C, and 3-prong AC) for various needsPadded zipper case for easy carryingGood priceCons:Charging time can be long (in took more than an hour to get the top couple percent)May not run CPAP machines with humidifier and heated tubing for very longNot suitable for running high-power devices or multiple devices at once (MAX 130W on AC)Heavier than expected for the travel purposesOverall a solid portable power bank with AC inverter at a great value. Can use it at home as a quick emergency power source or in the car. It's even possible to travel with it as the battery capacity within approved limits.

The description sounded great and just what I needed to keep my laptop up and running in the field. I tested it out from a full charge on this product, it only charged my laptop about 3% before it was completely drained. I charged it again to try again. It dropped the power % on the battery by roughly a 2% per minute. I don’t recommend this for charging a laptop. It works good for cell phones, but there are much smaller batteries out there to charge cell phones.

This is a well made powerpack

Solidly made and functions well. Powers all my devices without any issues. The 27000mAh capacity lasts a long time, Compact, reliable, and super convenient—an essential for anyone who travels with multiple devices. Highly recommend!

I use this as a “portable” power pack for a mobile software defined radio (SDR), and it’s perfect. Yes, it’s a bit heavy, but that’s to be expected for the power you are carrying. It’s far beyond a cheap pocket sized power pack. The full sized outlet is a key feature that sets it above the rest. I HIGHLY recommend this to anyone needing a reliable and long lasting power solution.

Does not provide power for more than 2 hours

I was amazed by how heavy this power bank is. It's not a pack-in-your-bag sort of thing as it would weigh you down. I can see how it would be valuable to have as a student or traveler: when you need to plug in (car, airport, cafe) but can't reach an outlet. It's good to have on hand (we're keeping this one in the car, not in our book bag) when and if the need for power arises; which can be often.While waiting for my son in hockey, I sit in the car to do work. So often my computer runs low on power. That's when I need this huge brick of power.

Worked great for an overseas trip we took. Small enough to carry on the plane and used to power a cpap on an overnight flight. Also. Are in handy during the northern ca power outages.
