I put my EcoFlow Delta 3 Max on a scale for my latest YouTube video, and it read exactly 44.8 lb (20.3 kg), a perfect match for EcoFlow’s spec. It measures about 19.4 × 9.4 × 12 inches and still carries a full 2,048Wh LFP battery and a 2,400W inverter, which works out to about 45.7 watt-hours per pound, the best ratio of any 2kWh-class station in my comparison below.
Is the Delta 3 Max heavy? For a 2kWh power station, it is very manageable. Below are my weigh-in results, what makes up that weight, how it compares with other stations, and easy ways to move it.
EcoFlow Delta 3 Max Weight and Dimensions at a Glance
- Weight: 44.8 lb (20.3 kg), and my unit read exactly 44.8 lb on my scale. EcoFlow lists the net weight as 20.3 kg with a ±0.4 kg tolerance, so individual units can vary by about a pound.
- Dimensions: 19.4 × 9.4 × 12 in (494 × 239 × 305 mm), length × width × height.
- Capacity: 2,048Wh (51.2V, 40Ah) LiFePO4 battery.
- Output: 2,400W continuous, 4,800W surge, 3,400W X-Boost (US).
- Carrying: two fixed handles, one at each end, so it is a balanced two-handed lift.
- Energy per pound: 2,048Wh ÷ 44.8 lb = about 45.7Wh/lb.
My Weigh-In: 44.8 lb on the Scale
Screenshots in this post are from my YouTube video.
EcoFlow lists the Delta 3 Max at 44.8 lb, and when I set mine on my scale it read exactly 44.8 lb. For a real-world reference, I weighed a 45 lb dumbbell on the same scale, and it read 45.8 lb. So the power station is actually a pound lighter than that dumbbell. If you can pick up a 45 lb dumbbell, you can pick up the Delta 3 Max.
That is roughly two to three watermelons, depending on size, and 5.2 lb under the 50 lb checked-bag limit many airlines use. It is not a travel companion, though: a battery this big can’t go on a plane, so it is a road-trip and home-backup station.
What’s Behind the 44.8 lb?
The biggest share of the weight is the 2,048Wh lithium iron phosphate (LFP) battery pack. Next is the 2,400W inverter, which turns the battery’s DC power into AC for household electronics. The charging circuitry, cooling system, battery management system (BMS) and protective housing add the rest.
That weight pays off in power. In the video I use the AC outlets to charge cordless power tool batteries and run a work light at the same time, and the USB ports to charge a laptop, a phone and an iPad. Because those devices charge straight from USB, you don’t need to turn on the AC inverter for them. My Delta 3 Max power tools guide covers tool charging in more detail.

What 44.8 Pounds Feels Like
Numbers on a spec sheet are hard to picture, so here is what the Delta 3 Max weighs next to things you have probably carried before.
The Delta 3 Max (44.8 lb) weighs about the same as…
- 🥛About 5 gallons of milk
A gallon of milk weighs about 8.6 lb, so 44.8 lb is about 5.2 gallons. - 💧One full 5-gallon water-cooler jug
Water weighs about 8.34 lb per gallon, so 5 gallons is about 41.7 lb before you add the bottle. - 🏋️A pair of 22.5 lb dumbbells
That is 45 lb, just 0.2 lb more than the Delta 3 Max. A 45 lb plate at the gym feels about the same. - 🍉2½ to 3 average watermelons
The Watermelon Board puts an average watermelon at about 15 to 18 lb. - 🦃Almost three Thanksgiving turkeys
The National Turkey Federation says the average Thanksgiving turkey is about 16 lb. - 🎳Almost three 16 lb bowling balls
16 lb is the heaviest ball allowed in league play. - 🐶A 40 lb bag of dog food, plus a little
About 5 lb more than the big bag in your pantry. - 📦About 1⅔ cases of bottled water
A 24-pack of 16.9 oz bottles is about 27 lb. - 🧳Under a 50 lb checked bag
Most US airlines charge overweight fees above 50 lb, and the Delta 3 Max is 5.2 lb under that line. (It still can’t fly, since lithium stations this big aren’t allowed on planes.)
Delta 3 Max Weight vs Other Power Stations
Here is how the Delta 3 Max stacks up against its EcoFlow siblings and the popular Anker, Jackery and BLUETTI models, using each maker’s official spec page or manual.
| Power station | Capacity | Weight | Wh per lb |
|---|---|---|---|
| EcoFlow Delta 3 Max | 2,048Wh | 44.8 lb (20.3 kg) | 45.7 |
| EcoFlow Delta 3 Max Plus | 2,048Wh | 48.7 lb (22.1 kg) | 42.1 |
| EcoFlow Delta 2 Max | 2,048Wh | 50 lb (23 kg) | 41.0 |
| EcoFlow Delta 3 Classic | 1,024Wh | 26.6 lb (12.1 kg) | 38.5 |
| Anker SOLIX C1000 | 1,056Wh | 28.4 lb (12.9 kg) | 37.2 |
| EcoFlow Delta 3 Plus | 1,024Wh | 27.6 lb (12.5 kg) | 37.1 |
| Jackery Explorer 2000 Plus | 2,042.8Wh | 61.5 lb (27.9 kg) | 33.2 |
| BLUETTI AC200L | 2,048Wh | 62.4 lb (28.3 kg) | 32.8 |
| BLUETTI AC180 | 1,152Wh | 35.3 lb (16 kg) | 32.6 |
| Anker SOLIX F2000 | 2,048Wh | 67.2 lb (30.5 kg) | 30.5 |
Two things jump out. First, among the full 2kWh stations, the Delta 3 Max is the lightest on the list: 3.9 lb lighter than the Delta 3 Max Plus, 5.2 lb lighter than the Delta 2 Max, and more than 16 lb lighter than the Jackery Explorer 2000 Plus, BLUETTI AC200L and Anker SOLIX F2000. Second, the 1kWh stations like the Delta 3 Plus and Anker SOLIX C1000 are lighter overall, but you only get half the battery. Per pound, the Delta 3 Max gives you more stored energy than any of them.

Delta 3 Max Dimensions: Will It Fit?
| Power station | Size (L × W × H) | Weight |
|---|---|---|
| EcoFlow Delta 3 Max | 19.4 × 9.4 × 12 in | 44.8 lb |
| EcoFlow Delta 3 Max Plus | 19.4 × 9.5 × 12 in | 48.7 lb |
| EcoFlow Delta 2 Max | 19.6 × 9.5 × 12 in | 50 lb |
| EcoFlow Delta 3 Plus | 15.7 × 8.0 × 11.2 in | 27.6 lb |
| Jackery Explorer 2000 Plus | 18.6 × 14.1 × 14.7 in | 61.5 lb |
| BLUETTI AC200L | 16.5 × 11 × 14.4 in | 62.4 lb |
The Delta 3 Max is long and narrow rather than boxy. At 9.4 inches wide and 12 inches tall, it is about as tall as a standard 12-inch ruler and only a little wider than a carry-on suitcase is thick (most carry-on limits are 22 × 14 × 9 in). That slim shape slides easily into a car trunk and tucks next to the fridge without taking over the room.
Can One Person Move It?
✅ Verdict: yes, for most adults
At 44.8 lb with two balanced handles, most adults can lift the Delta 3 Max into a trunk or carry it across a room on their own. For long walks, stairs, gravel campsites, or anyone who would rather not lift 45 lb, a wheeled cart makes it a one-hand job.
Lift-and-Carry Tips
- Use both handles. Face the long side, grab one handle in each hand, and keep the unit close to your body.
- Lift with your legs. Bend your knees, keep your back straight, and stand up smoothly.
- Unplug first. Pull the charging cable and anything plugged into the front so nothing snags.
- Clear the path. Prop doors open and plan where it will land before you pick it up.
- Use a cart for stairs and distance. Strap it to the hand truck and let the wheels do the work.
Why You’d Move It Around
Weight only matters because a power station is most useful when you can take it to the thing that needs power. A road trip or campsite is one, and a power outage is the big one. My Delta 3 Max camping and 12V fridge guide covers the campsite side.
Power Outage: Moving It to the Fridge or a Fan
When the power goes out, the outlet you need is wherever the appliance is, so this is where portability earns its keep. A full-size refrigerator only draws a few hundred watts while its compressor runs, and its startup spike fits comfortably inside the Delta 3 Max’s 4,800W surge rating. On a hand truck, you can wheel the Delta 3 Max into the kitchen for the fridge, then roll it to the bedroom to run a fan.
My Delta 3 Max refrigerator runtime guide walks through the hour-by-hour math, and the Delta 3 Max home backup guide covers which circuits make sense during a longer outage.
Easy Ways to Move It: Wheeled Carts
As I say in the video, if 44.8 lb is more than you want to carry, a dolly or wheeled cart is the easy answer. The dolly in my video is the KEDSUM Heavy Duty Moving Dolly. All three are rated far above what the Delta 3 Max weighs. Strap the unit down with a bungee or cargo strap before you roll.
- KEDSUM 2000LBS Heavy Duty Moving Dolly (the one I used in my video): steel frame rated for 2,000 lb, six swivel casters with two that lock, and a platform that extends from 27.6 to 43.7 inches.
- voluker 330LB Folding Hand Truck Moving Dolly: rated for 330 lb as a four-wheel cart or 220 lb as a two-wheel hand truck, switches modes with no pins or tools, has 5-inch solid rubber flat-free wheels and folds to about 25 × 18 × 4.6 inches.
- Magna Cart Personal Folding Hand Truck: rated for 160 lb, weighs 9 lb itself and folds to 2.5 inches thick with a telescoping handle. Best if you want something that lives in the trunk next to the power station.
The Bottom Line on Delta 3 Max Weight
At 44.8 lb, confirmed on my own scale, the Delta 3 Max weighs a pound less than a 45 lb dumbbell and about the same as a full 5-gallon water jug or a pair of 22.5 lb dumbbells, yet it packs a full 2,048Wh battery. That is the best watt-hours-per-pound figure in this comparison and the lightest weight of any full 2kWh station on the list. Most people can carry it from the car to the campsite or from room to room, and with a simple folding cart, anyone can roll it to the campsite, the fridge or the workbench.
