DJI’s Power 2000 doubles the Power 1000’s battery to 2,048 watt-hours and raises continuous AC output from 2,200 watts to 3,000 watts, according to DJI’s published specifications. Both are lithium iron phosphate (LFP) power stations rated for 4,000 cycles and both carry 140-watt USB-C ports, but the larger model adds expansion-battery support of up to 22,528Wh, more outlets and higher solar input. The choice comes down to how much you need to run, for how long, and how far you carry it.

Specs side by side
| Spec | DJI Power 1000 | DJI Power 2000 |
|---|---|---|
| Capacity | 1,024Wh | 2,048Wh |
| Chemistry | LFP | LFP |
| Continuous AC output (US) | 2,200W | 3,000W |
| Short-duration / peak | 2,600W total (about 30 s, US), 4,400W peak | 3,000W sustained until depleted |
| AC outlets | 2 | 4 |
| USB-C | 2 × 140W | 2 × 140W + 2 × 65W |
| USB-A | 2 × 24W | 4 × 24W (QC 3.0) |
| Expansion batteries | Not supported | Up to 10, 22,528Wh total |
| Cycle rating | Over 70% after 4,000 cycles | Over 80% after 4,000 cycles |
| Weight | About 13 kg (28.7 lb) | About 22 kg (48.5 lb) |
| Fast AC recharge (US) | Up to 1,200W | 0–80% in about 55 min |
| Warranty | 5 years | 5 years |
Figures come from DJI’s spec pages and store listing. DJI notes the Power 1000’s 1,200W grid recharge requires the battery to be at least 60% charged and the room between 68°F and 95°F.
The five differences that matter
1. Capacity: runtime doubles
At 2,048Wh, the Power 2000 stores twice the energy. Anything you run lasts about twice as long on the larger unit, before conversion losses. That’s the single biggest reason to step up.
2. Output: 3,000W vs 2,200W
The Power 1000 already covers most single appliances: a microwave, coffee maker, or circular saw sits under 2,200W. The Power 2000’s extra 800W lets you stack loads, for example a 1,500W space heater plus a 1,000W microwave. For background on how inverters handle surges, see my explainer on pure sine wave vs modified sine wave.
3. Expansion
The Power 2000 connects up to ten expansion batteries for up to 22,528Wh. The Power 1000 cannot expand, so its 1,024Wh is fixed. If home backup is part of the plan, that difference matters more than any other spec.
4. Ports
Four AC outlets versus two is the practical change; you can run a fridge, router, lamp and phone charger without a power strip. The Power 2000 also adds two extra 65W USB-C ports.
5. Weight and size
At about 13 kg, one adult can carry a Power 1000 to a campsite comfortably. The Power 2000’s roughly 22 kg is better suited to staying in a vehicle, garage or home.
Worked examples: runtime estimates
These are my estimates using an assumed 85% inverter efficiency for AC loads. Real runtimes depend on load cycling, temperature and battery age.
| Load | Avg watts | Power 1000 (≈870Wh usable) | Power 2000 (≈1,740Wh usable) |
|---|---|---|---|
| Wi-Fi router + modem | 20W | ~43 h | ~87 h |
| Starlink Standard | ~75W | ~11.6 h | ~23 h |
| Full-size fridge (cycling) | ~60W avg | ~14.5 h | ~29 h |
| CPAP without humidifier | ~30W | ~29 h | ~58 h |
| 1,000W microwave | 1,000W | ~52 min | ~1.7 h |
| 1,500W space heater | 1,500W | ~35 min | ~70 min |
Example: an overnight outage
Suppose you want to run a fridge (60W average), router (20W) and a few LED lamps (20W) for 12 hours. That’s 100W × 12 h = 1,200Wh, or about 1,410Wh from the battery after 85% efficiency (estimate). The Power 1000 would run short by several hours; the Power 2000 would finish the night with roughly 20% left (estimate).
Example: a weekend car-camping trip
A 12V fridge averaging 40W for 48 hours uses about 1,920Wh. If the fridge runs from a DC connection rather than AC, losses are smaller, but even so the Power 1000 alone won’t cover the full weekend without solar. My 12V fridge camping test with the DELTA 3 Max shows how much daily solar helps.
Who should buy which
| If you… | Pick |
|---|---|
| Carry it to campsites or job sites by hand | Power 1000 |
| Fly drones and want fast DJI drone charging in the field | Power 1000 |
| Want overnight home backup for a fridge and network | Power 2000 |
| Plan to add batteries over time | Power 2000 |
| Run 2,200–3,000W loads or several appliances at once | Power 2000 |
| Want the lowest upfront cost for 1kWh-class power | Power 1000 |
Cost per watt-hour
Listed at $699 and $1,299 at the time of writing (prices change often), the Power 1000 works out to about $0.68 per Wh and the Power 2000 to about $0.63 per Wh (estimate). Spread over 4,000 rated cycles, both land in the mid-teens of cents per lifetime kWh (estimate). In short, the bigger unit isn’t a premium per watt-hour; you pay roughly in proportion to capacity.
Home backup considerations
For whole-circuit backup you’ll want a proper connection method rather than extension cords. My guide to transfer switches vs interlock kits explains the options, and the home solar battery guide covers when a fixed battery system makes more sense than a portable one.
By the numbers: derived comparisons (estimate)
Dividing DJI’s figures against each other shows where each unit stands out:
| Metric | Power 1000 | Power 2000 |
|---|---|---|
| Watt-hours per pound | ~35.7 Wh/lb (1,024 ÷ 28.7) | ~42.2 Wh/lb (2,048 ÷ 48.5) |
| Hours at its full continuous output | ~0.4 h at 2,200W | ~0.58 h at 3,000W |
| AC outlets per 1,000Wh | ~2 | ~2 |
| Maximum system capacity | 1,024Wh | 22,528Wh |
The Power 2000 packs more energy per pound, but it’s still about 20 lb heavier to carry. Both run their full rated load for less than an hour. Big inverters are for short, heavy jobs, not all-day use at full power.
Worked example: a work-site day (estimate)
A carpenter running a 1,500W circular saw for about 10 minutes of actual cutting (250Wh), recharging two tool batteries at about 100W each for an hour (200Wh), and playing a 20W radio for eight hours (160Wh) uses about 610Wh at the outlet. At 85% efficiency, that’s about 720Wh from the battery. The Power 1000 covers it with about 30% left, and it’s the one you’d rather carry from the truck. The Power 2000 would cover two days of the same work before needing a charge.
Worked example: growing the Power 2000 for home backup (estimate)
DJI’s 22,528Wh maximum with ten expansion batteries works out to 2,048Wh per expansion battery. With two added, the system holds 6,144Wh. A 100W base load (fridge, router and lights, as in the outage example above) would run for about 52 hours (6,144 × 0.85 ÷ 100), a little over two days. Each added battery extends that by roughly 17 hours at the same load. The Power 1000 stays at its single 1,024Wh, so anyone planning for multi-day outages should start with the 2000.
FAQ
Is the DJI Power 2000 just two Power 1000s?
No. It doubles capacity, but also raises continuous output to 3,000W, adds expansion support, and doubles the outlet count.
Can the Power 1000 use expansion batteries?
No. Per DJI’s comparison, the original Power 1000 does not support expansion; the Power 2000 supports up to ten batteries.
Which charges faster?
DJI rates the Power 2000 at about 55 minutes for 0–80% on a US 120V outlet. The Power 1000 recharges at up to 1,200W from the wall under the conditions DJI lists.
Do both use LiFePO4 batteries?
Yes, both use LFP cells rated for 4,000 cycles.
Can either run a space heater?
Yes. Both handle a 1,500W heater, but the Power 1000 would last only about 35 minutes and the Power 2000 about 70 (estimates).
Which is better for an RV?
For short trips with modest loads, the Power 1000. For air-conditioner-adjacent loads or multi-day stays, the Power 2000 with expansion. See my 12V vs 24V vs 48V guide for fixed RV systems.
Can one person carry the Power 2000?
At about 22 kg (48.5 lb), most adults can lift it a short distance, such as from a car to a porch. For regular carrying to campsites, the 13 kg Power 1000 is the easier unit.
How many expansion batteries do I need for two days of backup?
For a 100W average load, the Power 2000 plus two expansion batteries gives about 52 hours (estimate). Higher loads need more batteries.
Which one is better value per watt-hour?
At the time-of-writing prices above, the Power 2000 is slightly cheaper per watt-hour, at about $0.63 versus $0.68 (estimate). The gap is small, so pick on capacity, weight and expansion rather than price per Wh.
Bottom line
The DJI Power 1000 is the portable one: about 13 kg, 2,200W and 1,024Wh, enough for camping and work sites. The Power 2000 is the backup one: twice the energy, 3,000W, four outlets and room to grow to more than 22kWh. Match your choice to whether you’ll carry it or keep it plugged in.
