6.7lb 500W(Peak 1000W) Portable Solar Generator (UPS, Power Inverter) - 330Wh Battery - Solar/AC/Car Charging Cable - 2 AC & 4 DC 12V & 4 USB Ports

After doing a decent amount of research, I found this 500watt pure sine wave (1000watt peak) lithium ion battery pack/inverter to be the best option out there. I wanted a way to solar power my electric bike with my 100 watt Renogy Eclipse panel. This unit has a solar charge port that charges the battery without the need for a separate charge controller. I am quite pleased with the quality and functionality of this unit. It is very quiet (zero noise). I would highly recommend this product to others and may buy another one.

AMSU 500W(Peak 1000W), 330wh Battery,Portable Solar GeneratorProduct shipped fast and came in a well protected/packed box. I have been researching "portable solar generators" for a few months now, as we wanted a quality and relatively powerful system to power a laptop, a 12v fan, and a couple other small electronics while traveling/camping off the grid for the next year. This AMSU unit, compared better than all the units in its catagory. I was hesitant purchasing this unit, as it is not a very well known company. I'm VERY pleases I made the purchase. The unit is extremely well made and of very high quality. switches and plugs top notch, not cheap light gauge wire. Unit came with a fully charged battery, and all the accessories I needed to connect it to a 100w solar panel. I charged a completely dead Iphone 6s in 50mins from the units usb output, and it didn't even make a dent in the units 330mh battery. Very happy with this purchase and looking forward to hooking it up to my solar panel soon,One thing I'd like to see avail from AMSU is a battery pack, I'd like to have another battery pack that I could charge in tandem with the unit, giving me the ability to have more stored power if needed.All in all, so far an excellent product, true as advertised! Will post an update when I get some time with this very nice product.

Great product and light. This battery backup holds a charge for days while in use. It will easily run multiple televisions and DVD players, fans etc.. it was a great purchase and I am trying out the solar charge next.

I got this to charge a hoverboard (a OneWheel). Seems to give me at least 2 solid charges. The display is not remotely accurate (stays at 100% for a while, falls quickly, then charges peripherals well past 0%), but based on the performance I'm getting from it, the specifications on the product page seem to be. Great price for the amount of power it holds.

I have been very happy with this solar generator. I've been using an HQST 100W solar panel and it charges within 3 or 4 hours in direct sunlight (very much in line with the 333Wh rating of the battery and near-peak efficiency of the panel). Just know that a 100W panel is the max that should be used with this unit:https://www.amazon.com/gp/aw/d/B018BOK9WU/Also the solar panel (which had mc4 connectors) works perfectly with the mc4 cable included with this unit. No adapter necessary; they just snap in.Also I've tested the usb output for the 2.1A slot on the bottom with a usb meter. It exceeded the rating! I've also run a projector / speaker system that was pulling 130W or so and it was able to run for about 2 hours, so the efficiency with running on the AC inverter seems super reasonable.Really enjoying this and can't wait to take it camping.Can't recommend this AMSU li-330 more highly :) Was definitely one of the best prices per Wh and it's a very handsome unit. Lamp is super useful and layout is fantastic.

Great solar generator! I researched practically every solar generator being sold on Amazon, currently. For me, this product had the best intersection of battery capacity, features, and cost. It offers two AC ports with a combined output of 500W - this is much more than many of the other solar generators (with peak for 1kW). It also has four DC outputs at 3A each (max of 10A total), and four USB ports at 2A. I've depleted and charged this several times now, and have recharged with AC and also ALLPOWERS 100W 18V 12V Bendable SunPower Solar Panel Charger Water/ Shock/ Dust Resistant Solar Charger for RV, Boat, Cabin, Tent, Car, Trailer, or Any Other Irregular Surface.This also is a true UPS - if you need to keep electronics up with no downtime, this will send battery power out through all ports when input dies (whether AC, solar, or DC).I also like this uses lithium batteries - this would be crazy heavy if made with lead acid batteries. The only downside I can find (which is pretty minor) is that the resolution on the battery percentage isn't great - it tends to jump in 4 or 5% increments. Which really is fine considering how long it takes to charge and deplete. Comes with all the cables you'd need as well. Great value.

I have only used it for a couple of months, so I can't say anything about its durability, but otherwise exceeds my expectations and has been one of the better purchases I have made. Originally, I had wanted a 2000 watt pure sine wave inverter, but found that they take up quite a bit of space and are not cheap. This generator, is more like an uninterrupted power supply (UPS), and only runs at about 400 watt, but it gives me an additional 33 Ah of Lithium battery, and unlike my UPS at home, which is heavy, this is light, compact and efficient. I can easily run my hotlogic mini oven for several hours as well as my Ninja Express Chop Blender (product reviews for another day). It also charges my laptop battery, when other outlets are occupied. I don't really need a cumbersome, static 2000 watt inverter. If I decide to add a tent to my setup, I can easily detach it and use it away from my van. Much cheaper than a goal zero, too.
