The Ecoflow Delta2 has garnered praise for its high utility in outdoor activities such as camping, as well as a reliable backup power source for home use during blackouts, capable of running heavy appliances like refrigerators and microwaves.

Additionally, the optional solar panel combo and the possibility for battery expansion further enhance its value.

Should I Buy It?
If you're in need of a reliable, portable power station with rapid charging, extensive output options, and the potential for battery expansion, the Ecoflow Delta2 is a compelling choice despite its higher cost. Its utility in both outdoor and home backup scenarios, supported by its durable build and efficient solar charging capabilities, make it a solid investment for those seeking versatility and reliability in their power solutions.
I waited to write this review until we had the power station for a while. It comes with a little charge and doesn't take long to get to 100%. When you charge it to a 100%, it lasts quite a while. We've only used it a couple of times for very short random power outages of about an hour each time and it's still over 99%. The app is really helpful. We purchased this specifically for random power outages and in event of loss of power from storms/hurricanes in south Louisiana. This powerbank can last a few days to power fans, appliances, phones, etc. This powerbank is in addition to our gas generator. If you don't want to spend a lot of money on a whole home generator having this power bank is highly recommended for short term use.

Works well and powers a 5000 btu midea window air conditioner for about 3-4 hours on low cool. Charging time is pretty quick. Really has help in the hottest time of day during summer in AZ.

Bought a flexible solar blanket with these. They charged up really fast. You can plug them into a wall socket, and your cigarette lighter in the van and of course, the solar blanket. The best part of this is when we go camping, we have access to renewable power. Nothing like plug and play.

After connecting the extra battery the cable and plugs use as much space as an additional main battery would. Why didn't EcoFlow use a 90 degree extra battery plug? Why does the extra battery cost more even though it uses fewer components and is cheaper to build? Why buy an extra battery if it limits expandability? What an engineering FUFA! I'm not using the extra battery now because it consumes too much space when connected to the main battery. I learned via EcoFlow and other sources that all my main batteries can be daisy chained for extra power. According to EcoFlow daisy chaining the main batteries via power plug output to power plug charging input causes up to a10% available power loss. I'll take the loss and keep the versitle expandability. I think short of a 90 degree power connector you may be better off buying two main batteries. Thats because the second main battery usually cost less than the extra battery and it's better to have two main units should one go down than to have an extra battery that uses too much space and is worthless if the main battery dies. I can still use my extra batteries in the house for power outages but when traveling the extra batteries are of little use due to space constraints. It's sad that poor planning on EcoFlows part and a failure to correct the problem causes so much trouble. Even worse is the fact that they sell the extra battery with out informing folks they can just daisy chain their main batteries via the power plug. Update: Extra Battery Power Cord and EcoFlow Sucks! I'm changing my review from 3 stars to 1. Apparently EcoFlow didn't like my review and messaged me. At first their resolution seemed admirable but quickly changed to a "if you don't like them return them senario". So kinda like we don't care but could you please change your review. I'll keep the batteries and continue to educate fellow shoppers about what wate of money it is buying the extra batterty.

Love these. I'm using them for tent camping and they are perfect to run out lights at night, projector for movies, blow up air mattresses, etc and still have power to go. I used them for an entire weekend and didn't need to recharge it. But I also have the color panels just in case. They are pretty easy to carry, one hand each, and super quiet. Only 1 button to use to turn on and off. If you're looking for something affordable and easy, grab yourself a couple of these.

Great product overall, I was able to keep the my office setup running (network stack included) for almost 12 hours. The only issue that I had was when the battery flipped to drawing from the secondary battery it shut everything off due having to go into the settings on the extra battery and flipping on the AC switch. That really was a pain and something I would have assumed would have been on by default if the primary was flipped on. Outside of that, no real issues. I've also been able to run my full sized refrigerator off the pack (single battery) for ~14 hours. Definitely wait for sales prices.
