ECHOFLO RIVER 2 MAX

Would Not Recommend

It lasted for 4 weeks and failed in charging and Echoflow said it would be replaced but the do not ship to Alaska even though it had a 5 year warranty. They wanted to have an address in the lower 48 to ship this to. Will not recommend them or any of their products.

None

It's awesome. I brought it to the baseball field and hooked it up to the BSN pitching machine, and it worked really well. It gave me roughly 6 hours of use, more than enough. I also connected to other items and it performed well.

High quality product.

Outstanding product. Bought it to be prepared for hurricane power outages since I live in Florida. I read that it would charge from 0% to 100% in an hour from a standard electric outlet. The one I received charged from 48% to 100% in a half hour and works perfectly. Very happy with the purchase and would gladly recommend.

Never received product. Someone at Lowe's changed the delivery address from my house to a place in Texas while it was in-transit. They're investigating and I might get my money back in appx 20 days. Def not buying here again.

False advertising

Would Not Recommend

You sent me the wrong portable power station. I asked for a 500 watt station and you mailed me a 300 watt station.

Amazing! Perfect for base camp!

I love this power station! As an avid backpacker, I have a base camp set-up and this power station is perfect for that! It runs all my needed gadgets along with some comfort gadgets before & after my backpacking trip. Since it only weighs 13 lbs., it's easy to transport. Plus, it fully charges within an hour. And I have so many ways to charge it (in my vehicle, while driving to where my base camp is going to be; AC; USB & solar). Plus, it's so easy to use. This is perfect for outdoor trips, hous...
