Jackery vs Anker SOLIX: Weight vs Solar Input at 1 kWh

Jackery and Anker SOLIX compete almost exclusively at the 1 kWh class, and they’re priced so closely — $0.93 against $0.95 per watt-hour — that value doesn’t separate them. Two specs do, and they point opposite ways.

Head to head#

The two specs that decide it#

Weight: Jackery, by 4.6 lbs.

Model	Capacity	Weight	Wh per lb
Jackery Explorer 1000 v2	1,070 Wh	23.8 lbs	45
Anker SOLIX C1000	1,056 Wh	28.4 lbs	37

45 watt-hours per pound is the best in the class. If the unit gets carried — to a tent pitch, up stairs, in and out of a truck — that’s the spec you’ll notice every single time.

Charging: Anker, decisively.

	Jackery Explorer 1000 v2	Anker SOLIX C1000
AC recharge to full	100 min	58 min
Max solar input	400 W	600 W
Realistic solar per clear day	~1,200–1,600 Wh	~1,800–2,400 Wh

600 W of solar input is the highest in the 1 kWh class. With a full array in good sun the Anker refills completely in under two hours of peak, which changes what’s possible off-grid: you run loads during the day and still start the night full. Solar figures assume 60–70% of rated panel wattage across a good day, which is the realistic planning number rather than the sticker one.

What does the difference mean in practice?#

Capacity is within 14 Wh, so runtimes are effectively identical. Usable energy is rated capacity × 0.85 for AC loads, or × 0.95 on DC where the inverter is bypassed:

	Jackery Explorer 1000 v2	Anker SOLIX C1000
Usable AC energy	910 Wh	898 Wh
Household fridge (48 W avg)	19 hrs	19 hrs
12V camping fridge (13.5 W avg)	67 hrs	66 hrs
CPAP on DC, humidifier off	10.2 nights	10.0 nights
Home essentials (2,192 Wh/day)	0.4 days	0.4 days

So capacity is not the decision. Twelve watt-hours is under two percent — noise. Anything you can run on one, you can run on the other for the same length of time. That’s why weight and charging carry the whole verdict.

The derivations are in how long will it run a fridge and the CPAP guide.

How much is 4.6 lbs, really?#

It sounds trivial written down and isn’t in use. 23.8 lbs is a comfortable one-handed carry for most adults over a short distance; 28.4 lbs is the point where most people switch to two hands or take a break. Over a hundred yards from a car park to a tent pitch, that’s the difference between one trip and deciding to make two.

It also decides where the unit ends up living. Units that are annoying to move stay in the vehicle, which quietly halves how often you use them.

If it never leaves a van, a truck bed or a garage, ignore this section entirely — weight is free when you don’t lift it, and Anker’s charging advantage becomes the only thing that matters.

What about ports and everyday use?#

Both cover the essentials — multiple AC outlets, USB-C fast charging, USB-A, and a 12V DC socket. Anker’s 1,800 W inverter against Jackery’s 1,500 W is the one functional gap, and it only bites in a narrow band: a 1,600 W kettle or a large microwave runs on the Anker and not the Jackery. Below 1,500 W and above 1,800 W, they behave the same.

For CPAP use specifically, check that whichever you buy has a DC output matching your machine’s converter cable — running on DC rather than AC recovers about 10% of the battery, which is worth more than either brand’s spec advantage.

Where they’re level#

Both ship LiFePO4 cells with pure sine wave inverters, multi-year warranties, and genuine US support operations — which is the main thing separating either of them from the long tail of unbranded units on Amazon.

Chemistry used to be the headline difference between a cheap power station and a good one. In 2026 it isn’t: every current line from both brands uses it, so an older review telling you to pay extra for LiFePO4 has expired.

The thing neither does#

Neither expands. No add-on batteries, on either model. Whatever you buy is what you have, permanently.

That’s a real limitation for anyone whose needs might grow — and it’s the strongest argument for looking outside this matchup entirely. The EcoFlow DELTA 3 holds the same 1,024 Wh, costs $699 against $999, expands to 5,000 Wh, and has a 4,000-cycle cell. On the numbers it beats both of these; it’s 27.6 lbs, so Jackery still wins on weight alone.

Decision rules#

Choose the Jackery Explorer 1000 v2 when:

• You carry it — tent camping, walk-in sites, stairs
• You recharge at home between uses, so charge speed doesn’t matter
• You want the simplest possible interface

Choose the Anker SOLIX C1000 when:

• You run solar panels — 600 W input is the class best
• You need fast turnaround between uses
• You have a load between 1,500 W and 1,800 W

Choose neither when:

• You might need more capacity later — get an expandable unit
• Price per watt-hour is your priority — see Jackery vs EcoFlow for the $0.68/Wh option
• The unit is for home backup — one day of essentials is about 2,600 Wh, well past either

A note on solar generator bundles#

Both sell solar generator bundles — the same power station with panels included. Anker’s higher 600 W input means it can use a larger array productively; pairing 600 W of panels with the Jackery wastes 200 W, because the charge controller caps at 400 W.

If you’re buying a bundle, check the panel wattage against your unit’s input limit before assuming the bundle is sized sensibly. More in the solar generator guide.

What if neither is quite right?#

Worth naming, because this matchup has a blind spot. Both units are locked at roughly 1 kWh forever, and both cost around $999.

If capacity might need to grow, the EcoFlow DELTA 3 holds the same 1,024 Wh, costs $699, and expands to 5,000 Wh. On paper it beats both here on price, charge speed, cell life and expandability — losing only on weight to the Jackery.

If you’re buying for outage backup, one day of household essentials costs about 2,600 Wh. Neither of these gets there, and neither can be expanded to. Start at the home backup guide instead of this comparison.

If you only charge phones, lights and a laptop, both are more than you need. A 300 Wh unit covers that for a weekend at a third of the price and a third of the weight.

How we compared these#

Every figure on this page comes from our product spec database, which records manufacturer-published specifications — capacity, continuous and surge output, chemistry and cycle rating, weight, recharge times, solar input, port counts, warranty and MSRP.

Runtimes are calculated, not measured: usable energy is rated capacity × 0.85 for AC loads (× 0.95 on DC, where the inverter is bypassed), divided by the device’s average draw. Compressor appliances are duty-cycled rather than run at nameplate wattage, which is the single most common error in published runtime claims.

We have not tested either unit in the field, so you won’t find noise readings, thermal behaviour or long-term reliability here — we’d rather say that than invent it. Prices are MSRP.

On price#

Both figures are MSRP and both brands discount 30–40% on major sale events. Given how closely matched these two are, whichever is on sale is usually the right answer — a 30% discount dwarfs the two-cent-per-watt-hour difference between them at list.

Does the brand matter beyond the specs?#

A fair question when two units are this close, and the honest answer is: less than the internet suggests.

Both are large, established manufacturers with US warranty operations, proper certifications and pure sine wave inverters. Neither is a risk in the way an unbranded Amazon listing is. Anker’s background is consumer charging hardware and it shows in port selection; Jackery has been in portable power longer and its interfaces are plainer. Those are preferences, not quality gaps.

What we won’t tell you is which has better customer service, because we haven’t filed a warranty claim with either. Aggregated sentiment from review sites gets repeated across this whole category as if it were first-hand testing, and it isn’t. Check recent owner reports for the specific model you’re considering, particularly if it’s been on sale more than a year.
