i couldn’t get this to charge from the solar panels or even the wall. panels we’re out in the sun (no overcast) for hours. i am very disappointed in this product. i was really excited to use it.

product works as described. lots of wires and adapters included. however, no way to charge with usb cube or connector. cannot charge on the road in the car. had to order a separate adapter for $10 after paying $245 for the unit. cord should have been included for that price.

the solar panel puts out 45w+ under full sun, which is quite good for a 60w-rated portable folding panel -- no complaints there. the biggest plus for the power station is that it's very lightweight and portable; at only 5lb and less than 4 thick, it's thinner and lighter than similar 300w / 280wh class portable power stations. the 300w-rated pure sine wave ac inverter works well; i was able to power a rice cooker at 311w (per my kill-a-watt) without issues, with ac output holding steady at 114v and 60hz. (for testing power station ac output ratings, a purely resistive load like a rice cooker, electric kettle or incandescent light bulb must be used -- that is, nothing with electric motors.)however, i'm disappointed at the dc input / output performance. the 12-23v charge port is limited to maximum of 2.4 amps, meaning it takes over 8 hours to fully charge the internal 280wh battery from empty when using the included 15v ac adapter (and not much less when using the included solar panel). there are 4 usb ports, though not one is a usb-c. at least one usb-c port with some type of fast charging is mandatory in this day and age, in my opinion. the 12v dc output voltage isn't regulated, and the voltage starts at only ~12.4v (when the power station is fully charged), and slowly deflates as the internal battery discharges until it goes down to 9-10v. this output voltage is too low and can cause many 12v dc-powered devices to complain, underperform, misbehave or downright stop working. the led lamp at the back works well, but the light output is underwhelming. the dc input output ports are identical (both dc5521) and sit about an inch apart from each other, which can easily cause user confusion. on the plus side, the 12v dc output is rated for 10a max, which is not bad.bottom line, the small size, light weight and competent ac output of this power station redeems itself well for occasional light-duty camping / work site use with low-powered devices, but the slow charging, lack of usb-c and disappointing dc output performance keeps me from recommending it without reservation, especially given the price.

i originally got this to pair with a 100w foldable solar panel to use on the beach. the problem with that is, all of my 100w panels output at 5a, where this generator has a max input of 2.4a. i may cautiously try it, we'll see. the inluded wall charger is only 36w, so it takes a very long time to charge this large of a battery bank (75000mah according to the literature). the manual is scant on technical details, but the product page does mention that it has a bms built in, over voltage/current protection, and overload protection. it does have an 'intelligent' fan that only comes on when the unit gets warm enough. the display is not of much use other than to display battery charge (not in percent - just with bars), and which outputs (ac/dc) are turned on. in other words, you don't know the amount of current coming in or going out. it is a true pure sine wave inverter and i read just over 111vac at the outlets. it has 4 usb outlets, but they are all usb-a. at this price point, i think it wouldn't be asking for too much to have at least one usb-c. comes with a dc5521 to auto lighter adapter as well as a auto lighter charging cord. the light is on the opposite side of the display and has one brightness level, strobe, and sos. bright enough to light up a tent or to change a tire in the dark. as far as performance, it will power a 12v mini fridge for 8-10 hours if it's pre-cooled on ac, and a mid-range laptop for about 4 hours. it is light and compact, so that's a good thing. i don't hate it, but i wouldn't get another one, either. there are more feature-rich options available in the same price range. the current promotion ($80 off) puts the price more in line with what it should be without a promotion. it has potential, but still needs some refining. 3/5 stars.

thought it would last longer with the charge. the solar panels charge it up slow as well. i paid $300 for this and it just has a one day use.

i fully charged this product before i left home. i went camping within 2 1/2 hours. battery was completely dead. let it charge with solar panels did not charge at all plugged into car for two hours did not register charge returning

so, this thing would be pretty sweet if it came anywhere close to the listed specs.... i love the form factor, it's a nice size...but performance wise, this is hot garbage! don't buy this unless you can get it for maybe 50 dollars.--not 300 watts ac! not pure sine wave!one thing you will notice is the ac output says 300 watts max. when something says xxx watts ac max, that figure is basically meaningless. the only meaningful figure is the continuous output. and for this little jewel that number is less than 100.i have a 15 watt wi-fi router, and it runs that fine with the ac adapter...i have a laptop with a 300 watt dock/power supply (but the laptop only draws 100 watts max when the dock isn't engaged (just pass-through power). when this battery is fully charged, it can barely power my laptop (which generally draws about 30 watts. the laptop becomes glitchy and almost unusable. i quickly unplugged my laptop and i hope it didn't damage it.so basically, what i could determine from this is that this thing provides < 100 watts continuous, and it clearly isn't a pure sine wave either. it can handle a 15 watt adapter, and that's about it.--dc doesn't worki tried plugging in a car cigarette lighter pd adapter, and also i tried charging a portable air compressor using the 12v dc port (again with fully charged battery pack). the usb pd adapter made the battery pack glitch and turn off instantly (with no load plugged into the adapter). the portable air compressor did nothing.--not mppti plugged this into a 5 amp 20v solar panel (which is high quality and works very well). i measured the voltage and current several times... so evidently the maximum power point according to this thing is...13 volts and 2.4 amps. that's all it ever measured.so... like that's not the maximum power point, by my calculations... that's about 30 watts from a 100 watt solar panel. (and this panel delivers 100 watts in full sun). even if the voltage was held to 13 volts, i would understand.. batteries have certain charging requirements, but the current should have been 5 amps in full sun. pathetic.

very disappointed in this product. i’m still waiting after two days of charging only three bars. if anyone knows of the correction to this problem please post it. this is my first time stepping outside name brands. no more.

take note that the solar panel that comes with this unit will allow you to charge your phone while it's in direct sunlight, but you cannot charge the battery unit. i was under the impression you could charge the battery with the solar panel, but apparently that's not the case. i left this out in direct sunlight for 12 hours and never got beyond a single bar of power which lasts about 30 minutes with a small fan hooked up to it. you also cannot run anything ac from the solar panel, so if you're interested for the inverter alone, you're going to be disappointed, it won't allow you to run ac while it's charging.that said, you can charge it from the wall or a car, and with a full charge the unit is fantastic. i was able to power a tv, small fan, and my phone a couple times on a single charge for several hours. on another occasion i ran a box fan at full blast for about 6 to 7 hours before it ran out of juice. if you keep it charged, this is a must-have for power outages or camping.the imports are good with a couple usb ports and a type b (american standard nema 5-15) socket (like the wall socket in your home) for connecting small appliances like a tv, lamps, fan, etc... which will operate for hours. there's also a built in light that's fairly bright and useful.it's light, compact, sturdy, and well designed. if the solar panel actually charged the unit, this would be a 5-star review, but it does not work.

it lasted 4 days camping on a charge just charging two phones maybe 3 times but my friend came and needed to charge her laptop since she works from home and can work anywhere and was able to charge her laptop twice but once it was dead it took one full day to charge one line so took 2 1/2 days just to charge full again. if i wasn’t past the return date i would have sent it back.

takes forever to charge! even longer for the solar charging. max power is about 3 hours.

the power bank itself worked fine and charged quickly via a/c power or from a d/c source (e.g. cigarette lighter/charger connection in a vehicle). however, the solar panels never really provided a charge. i left it out in direct sunlight for 48 hours and it only charged about half a bar. i did not try to run anything directly off the solar panel (aka charge a phone). i was hoping this would be good for when i go off road / off grid, as well as helpful for power outages. but, it was a not go and i returned it.

i'm always sorry to have to leave a less than stellar review, but this falls short in so many ways compared to my several other solar generators.arrived with 2 of 5 bars charged...leaving 3 of 5 bars to go. well, i'm on hour 5 of charging via ac wall outlet (via the included wall charger, and this is typically the fastest charging method for one of these types of units) and it's still filling up that last bar to full.as of writing this review, i don't see any mention of this in the product listing, but the instruction manual that comes with it states that it takes 7-9 hours (i assume from empty to full) for a full charge via ac outlet, which just seems incredibly unreasonable for a station that only has an advertised (still yet to be tested...) 280 wh capacity. that is not a huge capacity, and i don't see why this should take nearly that long to charge.i can't imagine if the grid was down and i was using this -- as my sole power station -- and charging it by solar. it'd take days to charge considering optimal sunlight is short lived for solar charging on any given day. and in the end i'd have a 300w max, 280wh (although this is almost always stated to be higher than actual) station. this will be nothing more than a back-up on top of several back-ups that i already have, and i suppose for anyone that has nothing, it's better than nothing, but not by a lot.it does not show you how many watts are going in (when charging), nor how many watts are going out when something is plugged into it. i have small brick style power banks that have that functionality, so for a larger unit to have nothing more than the old style 5-bars to represent charge status in 20% increments is wild.it does support pass-through charging, meaning it will charge my phone will the unit itself is also charging, so that's something. my cell phone is pretty old, so it only supports fast charging (which i believe is somewhere around 15w) as opposed to super fast or lightening or whatever else technology has moved on to these days, and my phone does say fast charging when i plug it in, so that too is something.the instructions say that this is not intended for long-term storage, but rather as a daily use item. but seeing as how long this takes to charge, i cannot fathom using this as a daily generator. i'd spend 10x more time charging it than using it. so every few months i'll just check that it's charged up to around the 80% range +/- and repeat indefinitely, keeping it as a 4th string backup or to charge phones and such while reserving my other units for higher draw electronics (especially since i can fully charge those other units in anywhere from 30 minutes to a couple of hours...nowhere close to 7-9 hours!).the price-to-wh ratio, if there is no active promotion, is on par with far superior units out there, making this a poor value if it's not on some sort of (significant) sale, and even then, i'd recommend saving up and getting a better unit.2 stars because it does work to some degree, but it's lacking in pretty much every conceivable way to any other power station that i already own. if it didn't take such a ridiculous time to charge, i'd bump that rating up higher, but for what it is, i have no choice but to give what i still think might be too generous 2 stars.

wouldn’t charge via solar panels in 8 + hours of sun camping

i want to give it less stars but i’m not sure if it’s just the device or the actual solar panels. but seems to power devices on both solar generator and power bank….. but does not charge fast enough to be useful. arizona direct sun does not charge the generator up fast enough to use it. we’re already in the 90’s here….. if they could do a pick up from my door i would love a return label.

first day i was able to charge it right up with the solar panel. it took all day, but it finally did it. so, i plugged in a few items (table/emergency light) to charge them up, and it did it. next day, i woke to the battery being drained down to about two bars, so i disconnected all my devices and put it in charge mode. solar didn't charge it at all, so i plugged it into the wall. after two hours...the bottom bar didn't even move. very disappointed in this device since it's suppose to be a backup charging source...but you can't rely on it. huge thumbs down!!!
