Jackery’s Explorer 3000 v2 packs a 3,072Wh LiFePO4 battery and a 3,600W inverter (7,200W surge) into a 59.5-pound case, with five 120V outlets including a TT-30 RV plug, according to Jackery’s official spec sheet for model JE-3000B. In the U.S., Jackery now sells it as the HomePower 3000: its Explorer 3000 v2 product link opens the HomePower 3000 page, and Amazon lists the same 3,072Wh, 3,600W unit at $1,349 as of Oct. 17, 2026. This review covers the specs, charging options, runtime math for home backup and RV use, and who it’s the right fit for.

Design and Outlets
At 59.5 pounds, it’s heavy for a portable, but Amazon’s listing says Jackery’s cell-to-body design makes it 47% smaller and 43% lighter than comparable models of the same capacity. The outlet mix is built for home backup and RVs:
- Four 20A outlets for a fridge, sump pump, microwave or power tools.
- One TT-30 30A outlet for plugging an RV straight in. Jackery also lists welders, air compressors and pressure washers as uses for that port.
- Two 100W USB-C ports for laptops at full speed.
- A 12V car port at 10A for a 12V fridge or a Starlink Mini cable.
Jackery notes the neutral is floating, not bonded, which matters if you plan to feed a transfer switch. Have an electrician confirm the setup for your panel.
Charging Options and Times
| Method | Jackery’s figure |
|---|---|
| AC wall | About 2.5 hours (support page); 2.2 hours (Amazon listing) |
| AC + solar hybrid | 1.7 hours (Amazon listing) |
| 4 × SolarSaga 200W | About 5.5 hours |
| 2 × SolarSaga 200W | About 11 hours (Amazon: 80% in 9 hours) |
| 1 × SolarSaga 200W | About 22 hours |
| 4 × SolarSaga 100 | About 12 hours |
| Car fast charger (sold separately) | About 5.6 hours |
| 12V car socket | About 36 hours |
The AC input needs a source that can supply about 1,800W. Jackery says that if you charge it from another power station’s AC output, that station must be rated at 1,800W or higher. The same applies to a small generator.
Solar Wiring Rules
The two DC8020 inputs are wired in parallel internally, and Jackery’s rules are strict:
- Use 1, 2 or 4 panels. Three panels aren’t supported.
- Each port takes at most 2 panels, and both ports must have the same panel model and count.
- Don’t mix wattages (for example, 100W on one port and 200W on the other).
- For 4 panels, you need 2 SolarSaga adapters.
- You can’t charge from solar and the car at the same time, but you can combine wall and solar charging.
Two SolarSaga 200W panels on each port is the setup that reaches the full 1,000W. Our Jackery Explorer 1500 v2 solar charging guide explains the SolarSaga connector setup in more detail.
Runtime: Worked Examples
We assume about 85% usable output after inverter losses (our estimate) and include Jackery’s 22W standby draw when AC is on. So 3,072Wh × 0.85 ≈ 2,610Wh usable.
| Load (typical average) | Watts incl. 22W standby | Estimated runtime |
|---|---|---|
| Full-size fridge averaging 150W | ~172W | ~15 hours |
| Fridge + Wi-Fi router + lights (~230W) | ~252W | ~10 hours |
| CPAP at 40W overnight | ~62W | ~42 hours (5 nights at 8 hours) |
| RV air conditioner at ~1,300W running | ~1,322W | ~2 hours |
| Space heater at 1,500W | ~1,522W | ~1.7 hours |
For context, Amazon’s listing says it can power a household’s essentials for up to 15 hours and keep a refrigerator running for 1–2 days. That matches our fridge estimate once you account for the fridge cycling off. For more detail by load, our guides to CPAP sizing and running a space heater on a power station walk through the math.
Worked Example: A 24-Hour Outage
A fridge (150W average), a router (10W), four LED bulbs (40W total for 6 hours) and phone charging (20W for 3 hours) use about 3,600 + 240 + 240 + 60 = 4,140Wh over 24 hours. That’s more than the 2,610Wh usable, so plan on one recharge from solar during the day: four 200W panels at about 75% real-world output make roughly 600W, or about 3,000Wh in five good sun hours. Or cut the fridge’s runtime by keeping the door shut and letting it cycle less.
Charging Math: Why the Times Look Like That
Jackery’s charge times make more sense once you divide the battery by the input power. The “ideal” column below is simply 3,072Wh ÷ input watts, with no losses. The gap between that and Jackery’s figure is conversion loss, panels producing less than their label, and the slower top-off near full.
| Source | Input power | Ideal time (our math) | Jackery’s figure | Implied average input |
|---|---|---|---|---|
| AC wall | About 1,720W | ~1.8 hours | 2.2–2.5 hours | ~1,230–1,400W |
| 4 × SolarSaga 200W | 800W rated | ~3.8 hours | About 5.5 hours | ~560W (70% of rating) |
| 2 × SolarSaga 200W | 400W rated | ~7.7 hours | About 11 hours | ~280W (70% of rating) |
| 12V car socket | 8A × ~12.5V ≈ 100W | ~31 hours | About 36 hours | ~85W |
Worked example, planning a solar day. With four 200W panels you can expect roughly 70% of their rating in good sun, or about 560W. Five strong sun hours give about 2,800Wh, which refills most of the battery after the 24-hour outage example above. On a hazy day at half that output, plan on two days of sun to get back to full. The car socket is best treated as a top-up while driving, not a main charging method.
UPS Mode
Plug the Explorer 3000 v2 into the wall and your devices into it, and Jackery says it switches to battery within 20ms if the power drops. That’s fine for fridges, lights, routers and most electronics. Jackery says it isn’t a zero-millisecond UPS, so it doesn’t recommend it for data servers or workstations. In pass-through mode, AC output is limited to 12A.
App Features
Jackery lists these app controls for the 3000 v2:
- AC and DC output on/off, and live status.
- Battery Saving Mode (15%–85% charge window) for longer battery life.
- Quiet Charging Mode, which lowers charging power to cut fan noise.
- Timed charging plans and a Self-powered Mode.
- Solar generation analytics.
- Screen scheduling, auto-shutdown, temperature units and device sharing by QR code.
Two things it doesn’t support: emergency charging mode and adjustable AC charging speed.
How It Compares
If you need expansion batteries or 240V, look at the larger Jackery models. Our Explorer 5000 Plus review covers the expandable 120/240V option, and the live Anker SOLIX F3800 vs Jackery Explorer 3000 Pro comparison shows the older 3000 Pro. The 3000 v2’s strengths are its lighter build for 3kWh, the TT-30 port and fast AC charging in a single box.
Storage, Care and Resets
Jackery’s support page has useful details for a unit that may sit waiting for the next outage:
- Self-discharge: about 1–3% per month when not in use.
- Storage temperature: -4°F to 113°F for up to a month, 32°F to 113°F for up to three months, and 32°F to 77°F for a year. A cool closet beats a hot garage.
- Cold use: it can discharge down to 5°F, but it only charges from 32°F up.
- Not weatherproof: Jackery lists no water or dust rating, so keep it under cover outdoors.
- Reset: hold the Power and USB buttons together for five seconds. The screen blinks off and comes back showing the battery percentage. The same steps reset Wi-Fi and Bluetooth.
- Wireless back on: if you turned off Bluetooth/Wi-Fi, hold the USB and AC buttons for three seconds to turn it back on.
Who It’s For
- Homeowners who want a few days of fridge-and-essentials backup with solar recharge.
- RV owners who want to plug a 30A RV cord straight into the TT-30 outlet.
- Job sites running saws, compressors or small welders on the 20A and 30A outlets.
- Not ideal if you want to add expansion batteries later, since it doesn’t support them.
FAQ
Is the Jackery HomePower 3000 the same as the Explorer 3000 v2?
Yes, both are the 3,072Wh, 3,600W unit. Jackery’s U.S. Explorer 3000 v2 link opens the HomePower 3000 page, and the specs match.
How much does the Explorer 3000 v2 weigh?
About 59.5 pounds (27 kg).
How fast does it charge?
About 2.2–2.5 hours from AC, 1.7 hours AC plus solar, and about 5.5 hours from four SolarSaga 200W panels, per Jackery.
Can I add an expansion battery?
No. Jackery says battery packs aren’t supported on the 3000 v2.
Does it have a 30A RV outlet?
Yes, one TT-30 120V/30A outlet, plus four 20A outlets.
How loud is it?
Jackery rates the cooling fan at 30dB or less. Quiet Charging Mode slows charging to reduce noise further.
Can I charge it from a generator?
Yes, as long as the generator can supply about 1,800W. Jackery gives the same 1,800W minimum for charging it from another power station’s AC output. A smaller generator won’t keep up with the 15A AC input.
Can I use it while it charges?
Yes. In pass-through (UPS) mode, Jackery limits AC output to 12A, so keep plugged-in loads under about 1,440W while it’s on wall power.
How many years will the battery last?
Jackery rates it for 4,000 cycles to 70% or more of capacity. At one full cycle a day, that’s about 11 years. As a backup that cycles a few times a month, calendar age and storage temperature matter more than the cycle count.
Bottom Line
The Jackery Explorer 3000 v2, now sold as the HomePower 3000, gives you 3kWh and 3,600W in a 59.5-pound package, with a TT-30 RV outlet, 100W USB-C ports, a 20ms UPS and fast wall charging. Follow Jackery’s solar rules (1, 2 or 4 matched panels) to get the full 1,000W solar input. If you don’t need expansion, it’s a strong one-box backup for home or RV.
