Jackery’s HomePower 3000 and EcoFlow’s Delta Pro 3 target the same buyer: a homeowner who wants battery backup without a permanently installed system. The HomePower 3000 is roughly a 3kWh-class unit with a focus on simple, compact home backup, while the Delta Pro 3 is a roughly 4kWh-class unit with 240V output and deep home integration. Here is how to choose.
At a glance
Think of this as simplicity and compactness versus capacity and 240V flexibility. Figures below are class-level ranges rather than lab measurements; exact capacity, output and weight vary by production batch and regional version, so confirm the current spec sheet before you order.
| Factor | HomePower 3000 | Delta Pro 3 |
|---|---|---|
| Capacity class | ~3kWh | ~4kWh, expandable |
| AC output class | ~3,000-3,600W class, 120V | ~4,000W class, 120/240V |
| Weight class | ~60-70 lb | ~100 lb, wheels |
| Home integration | Transfer switch / plug-in | Home panel / transfer switch, 240V |
| Best fit | Simple 120V home backup | 240V loads, scalable backup |
Where the HomePower 3000 wins
Compact and lighter
A smaller, lighter unit is easier to store in a closet and move between rooms, which suits apartments and smaller homes.
Simplicity
Jackery’s reputation is built on straightforward controls. For users who want to plug in and go, fewer settings are an advantage.
Lower total cost
A 3kWh-class unit usually costs less upfront and covers a fridge, internet, lights and medical devices for a day.
Where the Delta Pro 3 wins
240V capability
Well pumps, some HVAC equipment and dryers need 240V. The Delta Pro 3 supplies it.
More capacity and expansion
Around 4kWh built in and support for extra batteries give it a longer runway for multi-day outages.
Home circuit backup
Integrating with a home panel lets it power selected circuits automatically, rather than relying on extension cords.
Runtime math on real loads
Runtime is simply usable watt-hours divided by load watts. We assume about 85% of rated capacity reaches your devices after inverter losses, which is typical for LiFePO4 stations running AC loads. About 1kWh of extra storage adds roughly six to seven more hours of fridge runtime, or about an hour more of sump pump operation.
| Load | Draw | HomePower 3000 (~3,072Wh class) | Delta Pro 3 (~4,096Wh class) |
|---|---|---|---|
| Refrigerator (avg) | 150W | ~17.4 h | ~23.2 h |
| Wi-Fi + laptop | 90W | ~29.0 h | ~38.7 h |
| Sump pump (running) | 800W | ~3.3 h | ~4.4 h |
| Window AC (small) | 550W | ~4.7 h | ~6.3 h |
| Microwave | 1,100W | ~2.4 h | ~3.2 h |
Where each unit fits in the house
A 3kWh-class unit around 60-70 lb can sit in a hall closet or under a desk and be rolled or carried to the kitchen when the power goes out. A 4kWh-class unit around 100 lb is better parked permanently in a garage or utility room next to a transfer switch or home panel. Decide where the station will live before you buy, because the best backup is the one that is already connected when the storm arrives.
Planning for multi-day outages
For outages longer than a day, recharge capacity matters as much as battery size. Both units accept solar, but an expandable 4kWh-class system paired with a larger array or a small generator will cover multi-day storms more comfortably than a 3kWh unit alone.
Checklist before you order
- Your peak load: add up everything that will run at the same moment and keep it under about 80% of the continuous inverter rating of the HomePower 3000 or Delta Pro 3.
- Your daily energy: multiply each device’s watts by its hours of use, total it, then divide by 0.85 to find the rated capacity you need.
- Surge: motors in fridges, pumps and compressors can briefly pull three to five times their running watts; check the surge rating, not only the continuous one.
- Recharge path: confirm wall-charge time, maximum solar input and whether car or generator charging is supported.
- Warranty and cycles: LiFePO4 units are typically rated for roughly 3,000+ cycles to 80% capacity; favour longer warranties and authorised sellers.
Which should you buy?
Buy the HomePower 3000 if…
you live in an apartment or small home, only need 120V, and want an easy, compact backup that covers a fridge, internet and lights for a day.
Buy the Delta Pro 3 if…
you need 240V, want to scale capacity over time, or plan to connect it to your home panel for circuit-level backup.
FAQ
Can the HomePower 3000 run a whole house?
Not a whole house, but it can run essentials such as a fridge, lights, internet and a few outlets for about a day. Central AC and electric heat are beyond its practical range.
Is the Delta Pro 3 worth the extra cost?
It is if you need 240V, expansion or panel integration. If your needs are 120V-only essentials, the extra capacity may sit unused.
Bottom line
The HomePower 3000 is the easier, more compact choice for 120V essentials, while the Delta Pro 3 is the more capable, scalable backup with 240V support. Match the unit to your home’s loads and outage history rather than buying the bigger number by default.
