I recently had the chance to test out the EcoFlow Delta Pro 3, and let me tell you—it’s a beast. It’s ultra-compact, ultra-high-capacity, and, yes, ultra-heavy. Designed for home backup, RVs, off-grid adventures, and even 240V power needs on the go, this power station takes portable energy solutions to the next level.
Powering More Than Just Your Camping Gear
The EcoFlow Delta Pro 3 isn’t your average portable power station. While many power stations can keep your phone charged during a camping trip, this one is on a whole different level. It can serve as a full-home backup, power an RV, sustain an off-grid lifestyle, charge a Tesla, or even run an industrial popcorn machine for hours (yes, I tested that!).
As one of the largest power stations in EcoFlow’s lineup, this third-generation model outperforms its predecessors in almost every way. With higher capacity, faster charging, and expanded capabilities, it stands out as one of the most advanced consumer power stations available today. If you need serious power output combined with high capacity, this is the station to beat.
Price and Availability
The EcoFlow Delta Pro 3 comes with a premium price tag. The base model costs $3,699, but it’s currently on sale for $3,199. Since its launch, the price has dropped slightly, but it remains a high-end option. For those looking to maximize its capabilities, EcoFlow offers several bundle options, including a solar panel package, a dual-fuel smart generator bundle, and an extra battery pack that can expand its capacity to a whopping 48kWh.
Unboxing & First Impressions
The first thing that caught my attention when unboxing the Delta Pro 3 was its compact size relative to its insane power output. However, that impression was quickly followed by shock at its weight. I’ve handled plenty of power stations, but even I wasn’t prepared for just how heavy this one is. Weighing in at over 113 pounds, it’s not something you’ll casually move around without assistance.
That being said, EcoFlow clearly anticipated this challenge. The Delta Pro 3 features an industrial-grade IP65-rated battery for dust and water resistance, a sturdy build, and most notably—a built-in telescoping handle. While I expected wheels, I was pleasantly surprised to find a retractable handle hidden underneath, making transportation much easier. Combined with large rear wheels, moving this power station doesn’t feel like a full-on workout.

Real-World Performance
Before owning multiple portable power stations, I never realized just how often I’d need one. Whether as a home UPS backup or for powering equipment in unexpected places, having a reliable energy source has proven invaluable.
Over the past few months, I’ve tested the Delta Pro 3 in a variety of situations—some practical for everyday users and others more niche. Here’s what I found:
- Home Backup & UPS Mode:
- It works seamlessly as an uninterruptible power supply (UPS) with a 10ms switchover time. This means your critical appliances, like refrigerators or medical equipment, won’t experience downtime during a power outage.
- If you want to power your entire home, you’ll need additional wiring and accessories, but for local plug-in solutions, it performs beautifully.
- Off-Grid & RV Use:
- The Delta Pro 3 provides a massive amount of power, making it an excellent choice for van lifers and off-grid setups. With solar panel compatibility, it can keep running indefinitely in the right conditions.
- Heavy-Duty Performance:
- During testing, I was able to use it to:
- Charge a Tesla (while it won’t provide a full charge, it does add a significant boost when needed).
- Power a giant industrial bounce house blower.
- Run a commercial-sized popcorn machine at full power for several hours, all while being plugged into a standard 120V outlet.
- During testing, I was able to use it to:
What makes this power station truly unique is that it delivers generator-level output without requiring gas or diesel. That means you can get 240V power anywhere without worrying about fumes or ventilation requirements.
