“I have purchased the Eco Flow River Pro and the additional battery. I have tested the generator on a tv, sky, and living room lamp and it comfortably gives me ample hours on all of these at once. If there are going to be power cuts (we have been warned of these) I'd recommend this for things like I have mentioned and charging phones, laptops etc. I could also add it to the Fridge if I added on the additional battery, for a few hours. It can charge from indoors on the solar panel. Not massive amounts of wattage but it was pulling 60-80 watts from near the upstairs bedroom window on a 200w solar panel on a fairly sunny autumn day. This generator is great for power outages or camping/caravaning.”
