THIS IS A VERY AFFORDABLE POWER STATION DURING A HURRICANE

REYNALDO THOMASNovember 29, 2025

This Portable Power Station work great for me. It did what i wanted it to do for me here in Jamaica. Because of Hurricane Melissa i am still without electricity. Hence the reason why i buy two of this power station. It is very convenient for me due to the fact that it come with so much outlet for charging devices such as laptop, smart phones and tablets. The quality of the power station is of industry standard. Its is not too big to carry around. It is great for emergency when there is no electricity at home. Read more

Working very well outdoors to power an LED floodlight.

ElleNovember 24, 2025

The 200W power station is working very nicely to power a single 10.5W LED floodlight outdoors. I don't have a working outdoor electrical outlet right now, and the floodlight is on a yard stake illuminating the exterior of my home. This power station keeps the light on all night. The power station is behind a planter on my front porch, protected from rain. I have a heavy duty outdoor extension cord connecting the light to to the power station. We are currently having nights in the 30's-40's, so it is operating in the cool weather. It will be interesting to see if the colder winter weather affects the length of time it will operate the light. It would be perfect for powering outdoor holiday lights; and I just ordered a second one to use for that purpose. Doesn't weigh much, so it is easy to carry. Perfect for my needs! This review is for the 200W Portable Power Station, Powkey 120Wh/33,000mAh Power Bank. Read more

Light weight, on sale is worth it.

Sheila PashleyAugust 6, 2025

Nice light weight power source. I use it at off grid camp to charge phone, and run a usb fan or my sleeping bag warmer. It's 200 watts so only last so long, I actually have two of them. Got them on sale so was a good deal. What I don't like is how long they take to charge. I have two 1800 watts by another brand and in approx and hour they are charged fully, this has the older battery tech so if how fast they charge is a concern this is not for you. Read more

Good functionality

Alex west brownDecember 8, 2025

It's been a few years still works and charges devices. Battery goes a lil iffy at times after expected use but that's if you let it over charge. Has even gotten a few dings and bumps and still works after a few years of constant use. Read more

Expensive Item is of poor quality and NO WARRANTY???!!!

Gary BurkholderNovember 21, 2025

I purchased this item from Amazon 11/30/2024. It worked fine for 10 months (Christmas gift, not used until late January 2025,) then the switch went bad, then the item failed to take a charge, so I now have a useless, expensive brick. I noted on the order the statement "Free refund/replacement until 1/30/2026." Upon contacting JC at Customer service, I got no satisfaction. he said the return window has closed..."When I challenged him on this, he showed me that if you click on that, it opens a window that tells you that 1/30/2026 only applies to items purchased during the 2025 calendar year. CUSTOMER BEWARE!!! Amazon posts a prominent and deceptive statement, then negates it in the fine print. That aside an expensive item that fails after just 10 months is infuriating and unacceptable. It is a total ripoff. For icing on the cake JC gave me a contact number for the manufacturer that turned out to be a bogus/incorrect number. I will be following up with Amazon again but if they continue to treat me like dirt. I will NEVER buy from this manufacturer or Amazon again!!!!! UPDATE: I called amazon back after being unable to contact the manufacturer and reached Ayanna since JC had given me a callback number if I got no satisfaction. From her I learned there is no warranty at all on this item CUSTOMER BEWARE of both POWKEY AND AMAZON. I expressed my extreme frustration to her and she was totally unsympathetic and unhelpful. A customer who buys frequently and never complains should get better treatment than this. NEVER WILL BUY ANYTHING FROM AMAZON FROM THIS POINT FORWARD. Amazon, you lost way more than you gained by ripping me off with cheap junk and lousy service!!! Read more

Effective portable powerhouse

Jason (Hendojo)November 9, 2024

I recently got my hands on the 200W Portable Power Station, Powkey 120Wh/33,000mAh Power Bank with AC Outlet, and it has been nothing short of a game-changer. From camping trips to unexpected power outages at home, this little powerhouse has proven its worth time and time again. First off, the build quality is top-notch. It feels sturdy and well-made, which gives me confidence that it will last for years. The multiple output options are incredibly handy – I’ve charged my phone, laptop, and even powered a mini-fridge all at the same time without any hiccups. One of the standout features for me is the LED light. It’s super bright and has been a lifesaver during late-night outdoor adventures. Plus, the battery life is impressive. I’ve used it for several hours on end, and it still had plenty of juice left. Setting it up was a breeze, and the user manual was clear and easy to follow. I also appreciate the compact design, which makes it easy to carry around without taking up too much space. Overall, I couldn’t be happier with this purchase. It’s reliable, versatile, and has exceeded my expectations in every way. If you’re on the fence about getting a power station, I highly recommend this one. It’s worth every penny! Read more
