I have to say out of all the solar generators I've tested over the past 3 to 4 years. This is by far my favorite. I like how it fits in my hand. I like all the features the ambient lighting it's made to last a lifetime. This thing will go all the way down to four minus charging. Most batteries go to 32. It'll go to 14,000 ft and most of these won't go hardly anywhere. Very well made made for the outdoors. Somebody who's serious off grid or has a cabin or fan or whatever. This is going to last you a long time and I'm very excited. Just to tell you the quality of this I mean everything about it. It just fit finish buttons where everything is located nicely. I have a nice area where I have all my plugins which makes sense. Somebody finally got that. The display is big and bright for us old folks. It has a huge battery capacity. This will run a a small refrigerator one that's designed for off grid of course, but it'll run it all night long and probably an electric blanket and other things you need. Super super super nice! Thank you for the opportunity of testing this. I look forward to seeing more products from this companyWhy did you pick this product vs others?:I wanted something that was high quality and that could be charged at low temperature because everywhere I go in the winter time it's usually colder than 32 and so I can't use it anyhowUsb ports:The USB ports are placed in the proper position and very solidly madeDurability:Just by using it in the past few days and a week. I guess this thing is a beast made very well. You can charge it charges at 400 w and has passed throughPower:This has three times the power of most solar generators their power supply. This one's hugeDesign:The design is impeccable

Solidly built, pure sine wave.
I am a fan of Hulkman products. I find them to be nicely designed/ engineered and well made from high quality materials.This Hulkman power station is no exception, it exudes quality. Hulkman also made some good decisions in terms of specifications to partially justify its comparatively high cost.I am basing that high cost assessment primarily on the device's capacity, 576Wh. If you look at the similar products that pop up on the Hulkman's product page, there are many competitive devices with nearly twice the capacity selling for approximately the same price. Especially if you are experiencing a power failure, capacity of your power station is an important factor.On a very positive note, the Hulkman's electrical output is pure sine wave as opposed to the cheaper simulated/modified sine wave. Pure sine wave is essentially the same electricity as plugging into your home's electrical outlet. Modified sine wave is stepped up to approximate that current. Pure sine wave is much more desirable, especially so for sensitive electrical equipment. You may have seen this mentioned when buying a battery back-up for your computer. There is a significant price differential between the two. Kudos to Hulkman for that choice.Hulkman's product listing features the fact they used Ternary Lithium batteries. These are Lithium batteries that use a special cathode. They are more expensive, are fast charging, have high energy density and are less affected by cold temperatures. There are disadvantages, however. They are more prone to thermal runaway making them less safe and they are capable of fewer charge cycles meaning they have a shorter life. Hulkman apparently opted to prioritize charging speed and cold weather performance. I'm not certain I would have used them, I would have speced Lithium Ion Phosphate batteries, but I understand why they made their choice.Materials are top notch as is quality of construction, save for the USB-C cover that doesn't want to stay "latched.". Hulkman also backs this up with a full five year warranty, they are definitely standing behind their product. It is extremely fast charging. It comes with a wall and 12 volt charging cables, both heavy duty. The display is nicely done and easy to read. It has one 12 volt, two USB-C and two USB-A outputs. There are three grounded AC outlets on the left side that Hulkman oddly chose not to show you in the listing's photographs so I took one. There are two available solar charging panels at extra cost.Hulkman has an available app to control or monitor several functions. I haven't installed it.I'm a little torn rating this power station. Price dependent I would give it 4 stars factoring in the capacity. Price independent, it earns five stars. 5 year warranty, pure sine wave output and high quality of construction.

Looks and feels premium
I haven’t tested it on the car yet, but I like it so far. The built quality is top-notch. I’m confident that when that day comes that I need to use it, it won’t let me down. Also, now I have a power bank for my laptop and phone!

King of all Jump Starters!
As of this writing I haven’t had to use it to jump start my car, but based off everything I’ve seen firsthand from having the product in hand. The packaging is absolutely amazing, and the feel of the product in hand feels really good too. The attachments that are provided are well thought out, and I really like how they’ve included a 12v lighter adapter that you can use to plug in an air compressor to inflate your tires. Not to mention the other ports for charging your phone and iPad. And it’s nice how it has two LEDS that have different functions, the display is very big and makes it easy to read. The battery clamps are very good quality and are sturdy, and it takes no time to charge up too. I like how it displays the amount of charge is left on the display and how simple the process is for when you’re ready to start your car. And lastly it’s real nice how they’ve included the steps, error codes and the solution for them that may display on the screen on the bottom of the jump starter. Very well thought out product, I hope I don’t have to use it anytime soon but I feel very confident for when the time comes. Great investment!
