I have been using the EcoFlow Delta Mini as my primary power source for minivan camping for three months. Before buying it, I tried building my own 12V system with a deep cycle battery. That worked, but it was heavy and complicated. The EcoFlow is simpler and more portable. Here is my honest review after using it daily.
What I Like
Fast charging. The Delta Mini charges from 0 to 80 percent in about an hour. That is incredibly useful when you stop at a coffee shop for a quick top-up. It is also quiet. Unlike a gas generator, you can run it inside the van while you sleep. It has multiple output ports including USB-C, AC outlets, and 12V carport. I can charge my phone, laptop, camera batteries, and run a small fridge simultaneously.
What I Do Not Like
The price. At around $600, it is not cheap. You can build a DIY 12V system with twice the capacity for half the money. But you lose the portability and fast charging. The other downside is that 882Wh capacity is enough for a weekend but not for a week-long trip without solar. With a 100W solar panel, it works for extended trips.
Real-World Usage
On a typical weekend camping trip, I use the Delta Mini to run a 12V fridge (30-40Ah per day), charge two phones overnight, run LED lights for a few hours, and charge my laptop once. The battery drops to about 40-50 percent by Sunday morning. With a solar panel on the roof, it stays topped up during the day. For winter camping when days are short, I charge it at a coffee shop or use the car alternator.
Verdict
The EcoFlow Delta Mini is a solid choice for weekend campers who want plug-and-play power without the hassle of DIY wiring. It is expensive, but the convenience is worth it for most people. If you are on a tight budget or camp for weeks at a time, build your own 12V system instead.
If you prefer a DIY approach, build your own 12V electrical system. See the full minivan camping guide.
