River Portable Battery & Solar Charger

easily portable battery charger

Excellent compact solar charger. Very light weight and portable. When paired with the 220 bifacial panel it's a pretty tough to beat for it's size. Excellent camping buddy.

Connected to my River, kept my portable refrigerator going all weekend

Traveled first year with our RV all the way from Virginia to Colorado…. Boon dock a couple of places and it was darn hot!! No power. We had our portable fan as to minimize RV battery but just could not cool it enough. I have added and upgraded our RV battery since last year. In addition I purchased the ecoflow pro, ecoflow pro extra battery, ecoflow portable generator, and also the ecoflow 400W solar panel. I have tested it out and so far it works pretty darn good. Granted it will provide only 6 hours to power essentials and running one of 2 15k BTU AC. Of course I had to add softstart to the RV AC (very easy install). I plan on buying additional extra battery from ecoflow and of course double capacity to the RV batteries as well. Anyway for a beginner RV’er this solved my problems for cooling without excessive manipulation to the RV power system. I just used the 30A converter to 50 A directly to RV power input…and will power on for at least 6 hrs without the 400w solar and portable generator (haven’t tested generator yet) connected. We will see how it goes this year but so far I am very happy with our ecoflow system. Side note I build solar panel holder with pvc wood as it is light, flexible, and easily transported in RV…set it up so it will take less than 5 min to set up.

Best portable battery. Fast charging time from wall outlet. Good mppt charging from solar. Lifepo4 batteries for a longer battery life. Extended battery. Big inverter to power most needs. EcoFlow quality. Way better than the Goalzero. Also the Bluetooth and wifi app is well designed

Having owned several brands of portable batteries for our off grid solar living, I was pleased to receive the DELTA 2 addition recently. The battery is extremely fast charging, reliable, and as advertised. Well designed and the app is a plus for monitoring. I love that it is lithiumFE battery based which will allow many cycles of charging.

The Goal Zero Nomad 20 is a great portable solar panel. I haven't given it a lot of use yet, but already it works as intended. I am able to charge my phone off it when the sky is overcast. In direct sunlight, it charges faster. I was also able to charge a usb battery pack, that doubles as a car jump starter, while out camping where there was no electricity. This was handy, considering I drained my car battery running a waffle maker. Downsides? it doesn't come with a carrying strap, though it isn't hard to add one.

We have been looking for a portable solar battery for tailgating and backyard football/movie watching. Watched and read many reviews and was excited when the Delta 2 came out and immediately purchased it. We already have 2-160w EcoFlow solar panels which we plan to use with the Delta 2. My only complaint is that although it can accept 500w charging, the 60 amp voltage limits it to 2 panels. Other than that, it is excellent and highly recommended.

I ordered the Eco Flow River Pro. Was very happy with it and it will do all that I need. I read reviews AFTER I bought it and was pleased to see how many were positive. I opted to add the extra battery. This will be a great way to extend my time off grid. I did not have any solar panels so I opted for the largest one Eco Flow made that would work for my current solar Generator. I got the 220 watt unit. It is foldable and has 2 sides that charge my River Pro. This system will be great to use here at the house when I need power out on the property and don't want to use a long extension cord or portable generator. So, I am a VERY happy Customer...

I hooked up the solar panels to the charger today. The panels and charger are on my in full sun. Started at 29% battery and now is at 42%. Charges at a slower pace. It’s been charging for about 2 hours. I have four panels for 400 watts.
