First, confirm the model name
This comparison is specifically about the Explorer 1000 v2. The original Explorer 1000, 1000 Pro, 1000 Plus and newer HomePower models are separate products. Likewise, DELTA 2 is different from DELTA 2 Max, DELTA 3 and DELTA Pro. Check the full name on the retailer listing, invoice and manual rather than relying on “1000” or “DELTA” alone.
Which runs appliances longer?
The 46 Wh nominal-capacity difference is about 4.5% of DELTA 2’s capacity. That does not prove a real-world runtime winner. Energy delivered at an AC outlet depends on conversion losses, standby consumption, battery condition, temperature and the load.
For a transparent planning example, assume that 85% of nominal capacity reaches the AC load. This is a chosen assumption, not a measurement of either unit. Runtime is capacity × 0.85 ÷ average load.
| Assumed constant average load | Jackery calculation | EcoFlow calculation |
|---|---|---|
| 100 W | About 9.1 hours | About 8.7 hours |
| 500 W | About 1.8 hours | About 1.7 hours |
| 1,000 W | About 0.9 hours | About 0.9 hours |
A cycling refrigerator is not a constant load equal to its nameplate wattage. Measure its energy use over a representative period and check compressor-starting requirements. Our refrigerator outage checklist covers load planning and food safety. Battery runtime alone does not establish a safe food-storage timeline.
Higher output is different from more stored energy
DELTA 2 has 300 W more rated AC output. That can matter when your simultaneous loads exceed the Jackery’s limit. For example, a hypothetical 1,200 W appliance plus 400 W of other equipment totals 1,600 W before startup peaks. Reduce the load or choose equipment with suitable headroom; do not plan around a short surge rating.
EcoFlow’s X-Boost compatibility feature does not change the rated inverter output. Its manual excludes some devices with strict voltage requirements. Check the appliance and power-station instructions instead of treating an advertised boost number as universal continuous power.
Charging and solar: compare the conditions
Jackery advertises a one-hour emergency full-charge mode; its technical table separately lists 1.58 hours for AC charging. EcoFlow advertises 0–80% in 50 minutes and 0–100% in 80 minutes under lab conditions. These are manufacturer claims with different modes and conditions, not our head-to-head results. Verify the mode, starting charge, temperature and available outlet before relying on a deadline.
Solar input limits are ceilings. A panel’s label wattage does not guarantee that input throughout the day. Check voltage, current, connectors and cables against the exact manual. If you need to recover a full battery every day, plan from your expected daily energy use and available sunlight rather than maximum input alone.
Does 4,000 cycles beat 3,000 cycles?
The two cycle claims use different remaining-capacity thresholds. A claim ending at 70% cannot be directly ranked against one ending at 80%. Neither establishes that your unit will last a particular number of calendar years. We do not have a controlled endurance comparison proving a longevity winner.
Which would we shortlist?
For frequent carrying: start with the Jackery if your loads fit and an all-in-one battery is enough. Decide whether the lower carrying weight matters more than output headroom.
For room to expand: start with DELTA 2 if a compatible extra battery fits your budget and storage space. Compare the complete system price and weight; a base-unit sale price is not the cost of an expanded setup.
For a long outage: neither base unit should be selected from wattage alone. Write down your essential loads, target hours and recharge opportunities using our outage load-priority guide. Check whether the calculated energy requirement exceeds the battery you are buying.
Buying checklist and current listings

Love the breakdown — the 1hr fast charge on the Jackery is a game changer for weekend trips. Took mine on a 2-night canoe trip and it charged my CPAP and a few lights no problem. Small caveat: it’s a bit heavier than I expected, but the carrying bag helps. Overall I’d pick Jackery if fast recharge is your priority.
Thanks Sarah — great real-world note about the CPAP. Weight is often under-discussed; I tried to mention the carry bag since it makes hauling easier for short hikes.
Nice! How long did the CPAP run on it? I’ve been worried about running overnight devices.
Joel — mine ran the CPAP ~7-8 hours at medium settings once, and still had juice left for phone charging in the morning. YMMV depending on CPAP model/settings.
Both look awesome ngl 😅 But can someone confirm if the Jackery really charges in 1 hour? Sounds like witchcraft. Also lol at my tent getting more battery power than my neighbor’s ancient generator.
I tested it — plugged into a proper 120V outlet and it did come close to full in about an hour. Pretty wild!
Nice comparison — quick question: the spec Wh is one thing, but how much usable capacity do you actually get after inverter and flags? Anyone tested real-world usable Wh for either unit?
I measured mine with a power meter: Jackery gave me about 920Wh under mixed loads. Your mileage varies with device efficiency and how often it spikes.
Short tech dive: both use LiFePO4 (LFP) — which is the real winner here for long cycle life and safety. Don’t sleep on cycle count: if you plan on daily discharge/charge (vanlife, full-time RV) LFP will outlive NMC packs by a lot. Also, look at BMS behavior under cold temps — some units throttle differently.
I’d pick based on expected usage patterns: frequent daily cycling = LFP + robust BMS. Occasional weekend use = either works fine.
We included a note about low-temp charging limits in the guide. If winter use is expected, consider a model with thermal management or plan to keep it in a warm spot while charging.
Totally — my neighbor ran his off-grid for a year and was amazed at how well the LFP handled deep cycles.
Excellent technical note, Michael. We tried to highlight LFP advantages in the article — especially for longevity and safety.
What’s the cold temp cutoff for charging those batteries? I’m in Minnesota and worry about winter use.
Mark — many LFP units won’t charge below ~0°C without internal heating. Some models have built-in heaters; otherwise you need to keep them insulated or in a warmer location before charging.
I ended up buying the Delta 2 for home backup after a storm last year. The extra AC headroom and the ability to chain solar made it worth it for me. Also the 100W USB-C is clutch for fast laptop charging. No regrets so far.
How many solar panels are you running with it? Thinking of pairing mine with a 200W setup.
Thanks for sharing, Olivia — good real-world example. The Delta 2’s AC capacity does make it more flexible as a backup solution.
Solar-minded comment (longer one):
If you plan to pair either with panels, remember charge speed from solar is limited by MPPT input. Jackery’s fast AC charge is lovely but when on solar you’ll be limited by how many panels you can realistically deploy. Delta 2 often supports more flexible solar inputs and faster total solar charging if you have space for multiple panels.
Also pro tip: shade really kills charging — even one panel in partial shade slashes the array. So choose panels and placement carefully if you depend on daytime recharge while camping.
Peter — exact same here. Also, a tilt stand for panels improved energy capture during early/late sun hours.
Agreed — learned the hard way with a single tree casting shade. Switched to more panels spaced out and saw big improvements.
Great solar tips, Laura — we tried to explain MPPT limits and the practical constraints of panel placement in the article. Shade is the silent killer of solar setups.
Weight/portability matters to me. The Jackery felt chunky but balanced; the Delta 2 seemed denser and more solid. If you’re hiking any distance, neither is ideal, but for car camping both work. Would’ve loved a shoulder strap option instead of just the bag.
If portability is paramount, look at lighter models or a smaller Jackery. These two prioritize power and cycle life over ultralight design.
Completely agree — both are car-camping oriented. We mentioned the carrying bag with the Jackery; some users jury-rig shoulder straps but that’s not an official solution.
I used a wheeled cart for the Delta 2 on a beach trip and it helped a ton. Felt silly but saved my back 😂
Price vs value: Jackery sometimes drops in price during sales, making it a no-brainer. Delta 2 is pricier but gives extra wattage and features. Warranty length and customer service matter too — anyone had warranty experience with either brand?
Thanks all — good tips. I’ll keep an eye on sales and the return policy before pulling the trigger.
Also check return window and who pays for shipping on RMA. That can make warranty headaches way less painful.
I had a minor issue with Jackery and their CS was slow but eventually helpful. EcoFlow replied faster to my warranty email, FWIW.
Quick take: Delta 2’s 1800W AC is the real flex here. If you actually want to run things like a microwave or more power-hungry RV gear without constant worry, that extra 300W matters.
But if you’re mainly charging phones, running lights, and a laptop for camping, the Jackery’s 1500W and 1hr fast charge make it tempting. Personally, I’d pay a bit more for the Delta 2 for the safety margin and future-proofing. Also, EcoFlow’s app integration is kinda neat (and slightly addicting).
Tony — good call on surge. I fried a cheap inverter years ago trying to cold-start a fridge. Learned my lesson!
Agree on the app — but it drained my phone battery when I left it connected overnight lol. Worth it for the convenience though.
1800W is nice but check surge ratings too if you want to start something like a compressor. Delta usually handles surges better in my experience.
