  1. Delen Boyd

    I have used the product for several days, and have had no issues. It powers electronics well, including my new 65 inch LED TV! I was originally hoping that it would run a small freezer in the event of power failure, but 500 WATTS is not sufficient for the compressor start up. It will run a dorm type fridge, which draws 450 watts at start up, then falls of to about 50 WATTS continuous, plus a light and my computer. Of course the period of time the unit will run is dependent on how many watts the item(s) draw, and whether that draw is continuous or if it cycles (like the dorm fridge). I also purchased a solar panel to charge this device, but have not had time to test it out. It is very light for the amount of power that it provides. I would recommend this for remote power applications for products requiring 500 watts or less.

  2. Dan Delorit

    Very quickly shipped, in a very safe package. The generator came fully charged and ready to work. The 110 volt charger and the 12 volt charger looks very high quality.

    Registering the warranty was a breeze.

    Works like a charm so far!

  3. Elvia Delgadillo

    The product looks nice and lightweight , I love that it has several charging ports and can be carried everywhere without pulling any strains on your body. Extremely light weight, not as heavy as others. Have not tied it yet but will do so pretty soon.

  4. David Pellot

    Lightweight, functional, portable and (hopefully) durable – this unit is definitely a step above my previous solution. I look forward to using it regularly!

  5. Jason Cox

    I bought this to have back up power in case the lights went out. And to run power while camping. It looks like it will do the job just fine.

  9. Prashant Kakad

    This was exactly the portable power station I needed to take my DJ sessions from my apartment to anywhere. I cannot wait to put this to work & have DJ shows from lakes, mountains & other outside attractions. The 500W power means I can run DJ speakers & 540Wh battery capacity allows me to DJ for a long time & have multiple products attached to it.

  11. Teresa L Heaps

    We have been able to charge our ipads, phones, headphones and even a CPAP machine. We love how portable it is. Are also excited that it has a light/lantern feature. We are extremely pleased with our purchase.

  12. Doug Lesan

    Lithium, DC Power, AC Power, USB options, Light, Long battery life. Just what I needed.

  13. Daniel Cardona

    This product so far has been great and the price for what you get is excellent!
    Like the fact that you can solar charge it while charging and running other devices. This is one solid unit.

  14. Anyelina Tejada

    Great power station, very light and the capacity is awesome, would definitely recommend to my friends, I hope you guys make more powerful ones soon! Thanks!

  15. Dave puechner

    Haven’t spent much time with it, but so far it’s functioning as advertised. Happy to see how compact and light weight it is.

  16. Thomas S Leung

    The battery looks well made with very good finishing. It has all the power socket types that we need. We plan to use it to power our 12V travel refrigerator. This battery can be charged by solar, car 12V socket and wall socket is wonderful. But the charging plug may detach from the battery easily. So, we have to check its connection from time to time, just to ensure the battery is connected.

  17. Christina Schaupp

    The power station works great. The charge lasts quite a long time. I am very happy with it.

  18. Christie Schaupp

    It’s a great power station and lasts a long time between charges. I have bought two of them so far.

  19. Jay Trivedi

    The product is robust, portable, reliable and very handy. It is very useful in short term power losses as well as outdoor events.

  20. Daniel Mulkiewicz

    I’ve used these generators and recommended to many of my friends for months now. These are highly portable, durable and have a smart design. I use this generator specifically as a UPS in my Jeep for my camping refrigerator. While I drive the Jeep charges the generator and when I stop the generator keeps the fridge powered. I’ve run the camping fridge in the back of my Jeep off this generator for over 48 hours (2 Days!) without recharging.

  21. Daniel Song

    I haven’t used it but it had the battery capacity and wattage I wanted and had great reviews.


    packaged well arrived much earlier then expected, so far great quality

  23. Alysann Fackler

    Great design and easy to use. I live in a hurricane prone area and did not want a gas powered generator. This is a perfect solution for a room fan if we lose power. Much less worried this year!

  24. Haydie Cruz

    It’s practical for emergency outages.

  25. Casey Hammett

    I bought OKPRO as a backup for power outages and camping. So far everything works fantastic! Looking forward to using it.

  26. rajesh rajadurai

    This product exceeded my expectations. The design is very intuitive to use. I like its portability. I used it to run a cpap machine on a camping trip. It was light to carry and lasted 3 days with some charge to spare….perfect. It has adequate number of ports to run the cpap machine, charge a cellphone and run a tiny camp fan….awesome. Thanks for this product.

  27. Dennis Stewart

    would like to do this part later. I need to have this product a bit way’ll before I make a comment. thank you.

  28. Lynn Luk

    Design is good and the price is good too!

  29. Alan Jennings

    I bought this to be prepared for power outages during hurricane season in Florida

  30. Victor Amendola

    Seems like a great product. Very intuitive. We ordered it to cover us in case of power loss.

  31. Dale Smith

    Great Deal help with all my charging and hobby charging and camping .

  32. yitah r wu

    Sturdy and functional, input power sensing makes this ideal for a solar-powered station when camping. I’ve run several smaller power tools (hedge clippers, oscillating multi-tool, hot glue gun, rotozip), from it, saving me a lot of money on upgrading those tools to cordless versions

  33. Maria Phelps

    Bought this and I have had this for about 2 weeks during the 2 weeks this is what i noticed: (this is pretty much the Rockpals)
    1. Charges my phone and other devices without issue
    2. Charges my phone and charge the battery at the same time
    3. Nice light (3 settings)
    4. Display shows how many hours left
    5. Nice price
    1. It can get really hot charging (not sure if this is normal)
    2. When I connect an inverter (12V) so I can take advantage of more AC plugs it turns off. So I cannot plug an inverter.

  34. Kyle Winder

    Great product. I use it to charge my onewheel on long trips. Great capacity for such a small unit!


    Excellent product! This should be helpful as an addition / alternative to a AC generator. Hope to see more excellent products from OKPRO soon.

  36. Eric Jaciel Alvarado

    I love the design. It is functional, powerful and portable. The charging abilities are ubiquitous and super convenient.


    I like the selection of ports as well as the carry handle that folds down. I bought this in case of hurricanes. I will be testing all the functions in the coming days. My unit came with several scratches, I wish it was packed more carefully.

  38. Christian Guzman

    I saw a review of your product at Matt Smith’s you tube channel and really liked it.

  39. Derek Gann

    Haven’t used it much yet, but plan to this summer. Should suit our needs well


    Im using this in coordination with a 150 watt solar panel to supply power to my tree house.

  41. Juan Gonzalez

    It is amazing product and would recommend to my family and friends.

  42. Atticus Brown

    Great value. Easy to use. Came 97% charged

  43. Jason Quackenbush

    good product…. small issues.

  44. ed portalatin

    having problem with manual. Before charging it states In one place of the manual to draw down the unit to zero then recharge. In another part of the manual it states to charge to 100% before using. Which one is it?

  45. Johnlee Ouyoung

    I really like this. It is good backup power and good for camping and for portability.

  46. garett

    This is a cool power station. It is small enough to keep in a vehicle for picnic stops at a park. Appreciate the LED light bar as it makes plugging and unplugging at night much easier.

    Looking forward to a lot of good use from this power station over the next camping season.

  47. Waleska Suarez

    Rey nice design very compact and perfect for the medical equipment we have in case of a black out

  48. Shoua Lo

    I like that everything is on one side. I also like the feature that allows me to turn on and off with any of the buttons. It’s also not too heavy or too light. The many power attachments makes it easy for me to charge it multiple ways.

  49. Bill Le

    I only have it for a day (less than 24hours). It has been working so far. I just wish it can handle more wattage like other power station I saw listed on amazon. I saw one that could do up to 1000w.

  50. Carson Zheng

    I received it yesterday and it looks sturdy.
