Review:I had ordered two of these Krisdonia Chargers to take with me on my trip to San Diego for FanDuel's World Fantasy Baseball Championship. We were going to compete for $1.5 million dollars on fantasy baseball and EVERYONE was going to bring their laptops or smartphones to use for the championship. Not knowing where exactly the event was going to be held and not knowing the amount of outlets that were going to be available due to the amount of electronics that were going to be brought to the event, I bought this. You can charge a large variety of laptops and cellphones from this power bank. I purposely ordered two-if one goes dead, I can swap it out and plug the other fully charged one in. I finally ordered it and there was a delay in getting it. Unfortunately, it was accidentally put on the wrong plane and was subsequently dropped and damaged during transit and Amazon done a really good job of replacing the items for me when they were damaged during transit. It didn’t matter because I ordered it in March and didn’t need it until August, so it getting damaged was no big issue. When I travel or order something for the holidays, I factor in delays in shipping like this just in case and order ahead. Anything can happen from point A to point B. I don’t wait until last minute to order stuff. A week and a half later I got both of them. It came in one long box with two smaller boxes. The first of the small boxes had the battery pack and a grey pouch to put the device in. The second box had all of your chargers, adapters and various adapters to fit into various AC ports on laptops. I took it to San Diego with me. Now in the description, it states that you may not take it with you on your flight. This is only partially true. Any battery pack over 120V but under 180V MIGHT be able to go on the plane with you. FAA requirements state that you must ask permission from the airline first before you can bring it on board. I did it with American Airlines. They said that I was OK as long as I had it with me in my carry-on bag and I got both on the plane without a problem. I don't think though the TSA people or the ticket agents really knew what it was anyways and they didn't really ask for proof that I asked them permission if I can carry it. It passed all the X-Ray tests at the airport and as long as it remotely didn't look like a bomb or something, they didn't give a crap and they waived it through. I don't think the TSA knows themselves what to flag and what not to. That's not their job to do that-it's the FAA and nobody from the FAA was there to help check bags for that sort of stuff. If the airline or TSA didn't care, neither did I and I didn't bother checking it again on my return flight. Anyways, when I got to the venue for the contest, lo and behold, it did not have a plug in site and I was the only smarta** in there that had a power bank. I was dying laughing watching contestants scrambling to change lineups on a dying phone and here I was with it on my table keeping my stuff charged while everyone else couldn't. I was in San Diego 3 days and one of the packs held its charge the entire 3 days-that's how big the capacity was on this. It took about 3 weeks after for me do get it down to zero. This was really powerful and done the job. A lot of the FanDuel contestants were interested in the power pack and took pictures of it so they could find it on Amazon too. They were impressed with it and it didn't occur to them to get one of these. I spread the message too. I loved this device. When you order it though and you intend to travel with it, just remember to take it to the airport and ask your airline carrier for permission to use it and you'll be fine. Read more

Review:***(update)*** Krisdonia contacted me the other day and told me they had seen my comment. They added passthrough capability, and wanted to send me one to evaluate. Needless to say, I accepted their offer, and the new model works flawlessly. I'm very happy with the powerbank. I'm also really impressed with both the customer service and the fact that they would take my complaint and put that function on their new model. ***(/update)*** The description and Q/A section made it seem like this could power other devices while the device itself is charging. It can't. As soon as you plug in it's charger, it cuts power to all devices. Read more

Review:Have owned this charger for a few days now. It works as promised. Massive capacity is enough to charge a surface book twice (I use mine with a Surface Book, Surface Pro, MacBook Air, iPad pro 12.9, ipad air 2, and iPhone 6s+). With this capacity comes some weight (a few pounds), but this is to be expected. It puts out plenty of amperage to keep up with surface devices at both 12V and 16V. Also charges MacBook air at full speed, very nice to include a magsafe 2 cable (not a lot of batteries include apple connectors). However, this device will NOT quick charge an iPad pro 12.9" via a USBC cable. I would guess this is because the Apple 29W USB C charger provides 14.5 Volts, while this battery only puts up to 12 V on it's USBC terminal. In any case, the iPad will only take ~12 watt charging rate at 5 volts even over the USB C cable. Also note that it will not charge devices while also charging the battery - appears to only operate in a single mode at a time (charge/discharge). Not the end of the world, though. The percentage indicator is not exactly linear, but this is also not a huge issue. Their calibration curve is such that it slowly declines between 80-100%, rapidly drops over the 20-80% range, and then slowly drops the rest of the way. Again, you still get the full 185 watt-h from the battery, but don't be alarmed when it seems like the capacity dropped a ton with only one tablet charge when the battery is in the middle of it's capacity curve. Buyers make sure you are aware - this 185 watt-hour capacity is LARGER than what is legally allowed through some airlines (typically 100 watt-hr max). It may not make it through security in certain countries. But this works great for long trips off the grid, or just nice for convenience around the house! Read more

Review:Why aren’t zero star ratings a thing? Maybe customer care can make this right so I can give this item 5 stars. Received the power bank in perfect condition. Held the power button for 2 seconds to make sure it turns on and charges through all output ports and then let it sit overnight to fully charge. The charge state showed 100% the next morning. Unplugged the power bank from the wall charger. Held the power button for 2 seconds to turn it on and nothing. The power bank will not turn on even tho the screen indicates 100% battery charge when plugged into the wall charger. The power bank will not power on, pass through charging no longer works.

Review:This is a solid power bank. The only problem is that you cannot charge power bank and devices at same time which I think is a significant shortcoming. Read more

Review:Giving this review after 1.5 years. The price is worth the product and is long lasting. Can charge my iPhone 12 Pro more than 20-30times with my iPad on the second port 5-10 times in a single charge . Although the button gets delicate after using it to change the voltage but works properly. Does not heat up like other power banks. Have taken it for a weekly road trip at 100% and by the end of the trip it only gets too 15% without needing it to charge. Overall worth the money and quality Read more
