powkey200W Portable Power Bank with AC Outlet, 146Wh Rechargeable Backup Lithium Battery, 110V Pure Sine Wave AC Outlet for Outdoor RV Trip Travel Home Office Emergency

I bought this item for travel, it was working great until one day it just stop working. I was unsure reason why, as I only had this item for about 1 year. First let me say that it worked great very easy for travel, it come in case travel case which is great. It has a wall plug and plug for your car, but if you have a EV car you are out of luck. Very long battery usage I was stuck at the airport and battery lasted for about 6 hour with having to plug it back in.I reach out to the company and ask for help to trouble shoot, I received a quick response, and they tried to walk me thur the issues I was having with no resolve. I was ask to do a video of the issue I was having. So I did a video and sent it to the company, I was ask to send the Powkey back so they could take a look at it. The Powkey was unable to be fixed so the company sent me replacement Powkey. I just want to say, they will try to fix the issue first, and there will be several emails between you and the company to try to fix the issues and you might have to do one than one video to send to them and you might have to send the Powkey to them to look at it which you have to pay for the shipping.I like companies that will help resolve issues with there products, I would buy from this company again because I think there customer services is great. I also want to say I was not paid to do this review and I bought this Powkey with my own hard earn money.

The media could not be loaded. I have three basic types of power banks: 1) Small units that fit in a backpack or briefcase for overnight use, no more than 10,000 mAh; 2) Larger units that will supply several days of power for my phone on a backpacking or canoeing trip with 20,000 to 30,000 mAh, and; ) Big power supplies that add AC out to the mix so that I can run 120 AC if I need to from the battery.These battery packs fall squarely in the third category. They're big and heavy, but not so big and heavy that I couldn't put one in a suitcase if necessary for a trip. In other words, they're not the common lunchbox sized battery units that are really only useful for car camping.These batteries (I purchased two of them) took several hours to charge, and they were already half-full on arrival. After charging them I plugged my Christmas tree into one battery's AC output. The battery powered the tree lights for 3.5 to 4 hours before becoming fully depleted. I then recharged the battery overnight. I didn't measure how long it took to charge from totally empty.I'm very pleased with these batteries. I got them to replace a Jackery 20,000 mAh with AC out and a Romeo Power Sabre of about the same capacity as the Jackery. These batteries were much cheaper than the Saber or Jackery which I purchased together about five years ago.

At first I really liked this power bank. But then out of no where after about 11 months of minimal use, it failed to turn on, recharge , nothing worked..completely dead.. Even with the power cord plugged in, it wouldn't work. It wouldn't turn on or take a charge.. I have portable anker power banks that have lasted 5 plus years. This didn't even last a full year. Of course it's passed the return window so I have no recourse. Extremely disappointing as this was expensive (for me) and I bought for long work travels, emergencies, camping trips etc.. only used it a few times in my home.. and it failed completely right at their warranty period.. I'm still fighting this battle to get a refund..talked with Amazon, however, because it was past their return window and the companies warranty period, no go:( it was a 30 minute convo and they sent a message to the company telling me if they hadn't responded in 60 days, Amazon would contact me and go over refund options.. it's been 6 months and none of that has happened... Would not recommend this device to anyone. It will eventually fail you. The company doesn't stand by their products and something like this should have at least a 3 year warranty. Also, having the AC outlets are cool but they drain the battery 3 to 4 times as fast as the other ports even if your charging the same thing. I tested it to see if the AC or USB would charge my phone faster. Not only was the USB faster but the AC ports drained the battery much quicker. It reallyDoesn't matter because I wouldn't recommend anyone buy this product. Read the reviews.. look at how many people say the exact same thing.. don't fall for this scam product! Plus the company won't help you when the product fails. Just got further review, I never even took this out of it's case, took it outside, it was always in a comfortable room temperature environment. This has been one of my worst purchases on Amazon.. not only because it failed.. but because the company and Amazon won't help. Don't waste your money!
