QUICK VERDICT
A near tie on size — a real split on solar and output.
Both store 1,024Wh with LFP chemistry and roughly 4,000 cycles to 80%. Both weigh within half a pound of each other, which makes this the closest pair in the 1kWh class on portability.
So the decision comes down to two things. Anker offers 200W more continuous output and faster mains charging. BLUETTI offers a much higher solar ceiling and a wider port spread.
Choose the C1000 Gen 2 if you run higher-draw tools or appliances, recharge from mains often, and do not plan a large solar array.
Choose the Elite 100 V2 if solar is central to your plan, you want headroom for a bigger array, or you prefer more simultaneous ports.
One shared limitation is worth stating early: neither of these two supports battery capacity expansion. If you expect to grow past 1kWh, that is a different comparison.

Capacity and cycle life: two more ties
Both batteries are rated at 1,024Wh and both are rated for roughly 4,000 cycles to about 80% capacity. Neither offers a runtime or longevity advantage from the advertised figures, so both categories can be removed from the decision.
Nominal capacity is also not the same as usable AC energy — inverter conversion, internal electronics, standby draw and temperature all take a share. But because both start from the same nominal figure, that does not help separate them either.
AC output: Anker has 200W more
The C1000 Gen 2 is rated at 2,000W continuous; the Elite 100 V2 at 1,800W. For phones, laptops, routers, TVs, lights and most camping electronics, the difference is irrelevant. It becomes relevant when you approach the inverter limit.
BLUETTI advertises up to 2,700W Power Lifting and 3,600W surge; Anker specifies up to 3,000W peak. Neither should be read as continuous output — boost modes target suitable loads and are not a licence to run arbitrary motors beyond the normal rating.
| Device | Typical draw | Practical note |
|---|---|---|
| Laptop, phone, router, TV | 10–150W | Both handle easily |
| Refrigerator | 50–300W running | Both; check startup surge |
| CPAP | 30–60W | Both easily |
| Coffee maker | 800–1,200W | Both |
| Microwave | 1,000–1,500W | Both |
| Power tools | 500–1,500W | Both; Anker has more headroom |
| Hair dryer | 1,200–1,800W | Both near the limit |
| Several high-draw devices together | Varies | Check the total; Anker has more rated headroom |
Ranges are general appliance estimates for planning. Check the actual input wattage on the label of the device you intend to run.
Charging: Anker is much faster on mains, BLUETTI has far more solar
Mains charging is not close
BLUETTI specifies up to 1,200W AC charging with approximately 80% in 45 minutes and a full charge in around 70 minutes under its stated conditions. Anker's UltraFast mode raises maximum input to 1,600W with an advertised full recharge of about 49 minutes.
That is roughly a 20-minute gap to full, which is a meaningful difference if you recharge between jobs or move between powered locations during a day. The UltraFast mode is enabled through the Anker app.
If your station mostly sits fully charged waiting for an outage, this gap matters far less than it looks on paper.
Solar is where BLUETTI pulls ahead
The Elite 100 V2 accepts up to 1,000W of solar. The C1000 Gen 2 accepts up to 600W, with Anker stating roughly 1.8 hours to full under ideal conditions at 600W.
A 1,000W ceiling against a 1,024Wh battery means you can potentially recover most of the battery during a short window of good sunlight. The 600W ceiling is still practical — it simply limits how large an array you can usefully connect later.
Real solar output depends on sun angle, cloud cover, panel temperature, shading, panel configuration, season and location, so treat advertised recharge times as best-case rather than guaranteed. The input ceilings are the durable difference. See our solar buying guide before choosing panels.
This is also a difference BLUETTI has over the DELTA 3 Plus's rival strengths — see our Elite 100 V2 vs DELTA 3 Plus comparison for the third side of this group.
Portability: the closest category here
The C1000 Gen 2 is about 24.9lb and the Elite 100 V2 about 25.3lb — a gap of roughly half a pound, effectively nothing in daily use. Neither is hard to move compared with a 2kWh or 3kWh station.
Dimensions are where they diverge. The Elite 100 V2 is about 12.6 × 8.5 × 9.8 inches, while the C1000 Gen 2 is about 15.12 × 8.19 × 9.61 inches. The BLUETTI is considerably shorter front-to-back, which can decide whether a unit fits behind a seat, under a bench or in a narrow cabinet. If storage space is tight, that difference is worth more attention than the half pound.
Ports: a modest BLUETTI advantage
BLUETTI says the Elite 100 V2 can power up to 11 devices; Anker specifies 10 ports on the C1000 Gen 2. BLUETTI also provides one 140W and one 100W USB-C port, while Anker offers up to 140W USB-C.
The practical difference is small. Anker's single high-power USB-C port covers one demanding laptop; BLUETTI's second 100W port adds a little more flexibility for a second device without matching Anker's peak. For most camping and backup setups, only one of you will notice.
UPS and home backup
BLUETTI specifies ≤10ms UPS switching; Anker specifies 10ms. For most buyers those are the same category, and both are positioned for desktop computers, Wi-Fi equipment, NAS devices, CPAP machines and home-office electronics.
Treat both as essential-device backup. At 1,024Wh they can realistically support a mixed load of refrigerator, router, phones, laptops, lights and CPAP, but 1kWh disappears quickly under continuous high-power draw. Test the complete setup while grid power is available, and verify the requirements of sensitive equipment rather than assuming every device tolerates every UPS implementation.
The limitation they share
It is worth being direct about this, because it is the single factor most likely to make either purchase feel like a mistake later: neither the Elite 100 V2 nor the C1000 Gen 2 supports expanding battery capacity.
Anker's C1000 Gen 2 does not support capacity expansion and Anker's documentation states this clearly. BLUETTI positions the Elite 100 V2 as a standalone unit rather than a modular system. So if you buy either and later find 1kWh insufficient, your options are an independent second station or a different system — not simply adding a battery.
If that possibility worries you, the third model in this group is the one to look at. The DELTA 3 Plus vs C1000 Gen 2 comparison covers it, and our DELTA 3 Plus assessment explains how that expansion path works.
Camping, RV use and tools
Camping
Both are capable weekend car-camping units. The BLUETTI's shorter footprint helps when vehicle space is limited; its 1,000W solar ceiling becomes valuable on multi-day off-grid trips where you rely on panels rather than a wall outlet. The Anker is the better fit for shorter trips where you recharge at home and want a little more appliance headroom.
RV use
RV buyers should weigh storage space, solar charging and output. The BLUETTI's compact footprint and higher solar input suit RVs where the station is charged from panels and stored in a tight bay. The C1000 Gen 2's higher output suits running cooking appliances or tools. Neither expands, so an RV build with growing power needs should look at a modular system instead.
Power tools and job sites
This is Anker's clearest win. Tools with high startup demand or several devices used together can push inverter limits, and the 2,000W continuous rating gives 200W more normal headroom. Faster mains charging also suits job-site routines better than solar recovery.

Four questions that decide it
- Will you build a serious solar array? If yes, BLUETTI's 1,000W ceiling is the stronger choice. If you own one modest panel, the gap may never affect you.
- Will you run high-draw tools or appliances? If yes, Anker's 2,000W rating provides useful headroom.
- Do you recharge from mains frequently? If yes, Anker's faster charging suits your routine better.
- Do you expect to need more than 1kWh later? If yes, neither of these is the right purchase — look at a system that supports battery expansion.
One more variable can override all of the above: current price. Portable power stations are heavily discounted, so we do not treat list price as the measure of value. If one is substantially cheaper during a promotion, ask whether you will genuinely use the other's advantages.
FINAL VERDICT
Pick the priority, not the brand.
These two are within half a pound of each other and share capacity, chemistry and cycle life. The Anker SOLIX C1000 Gen 2 is the stronger choice for higher-draw appliances, mains-heavy recharge routines and job-site use, thanks to 2,000W continuous output and much faster AC charging.
The BLUETTI Elite 100 V2 is the stronger choice for solar-led planning, tight storage and a simpler standalone purchase, thanks to its 1,000W solar ceiling and shorter footprint.
And if you suspect 1kWh will not be enough in two years, neither of these is the answer — start with the DELTA 3 Plus vs C1000 Gen 2 comparison instead.
Still deciding?
Neither of these supports battery expansion. If you expect to need more than 1kWh later, start with the pairing that does.

Frequently asked questions
Which has more battery capacity?
Neither. Both are rated at 1,024Wh nominal capacity with roughly 4,000 cycles to about 80%, so runtime differences come from inverter efficiency, standby draw and load behaviour.
Which has more AC output?
The Anker SOLIX C1000 Gen 2 at 2,000W continuous, against 1,800W for the BLUETTI Elite 100 V2. Both advertise higher peak or boost figures that should not be treated as continuous output.
Which charges faster from a wall outlet?
Anker, by a clear margin: about 49 minutes to full using its 1,600W UltraFast mode, against about 70 minutes for the Elite 100 V2 at up to 1,200W. We have not measured either.
Which supports more solar input?
The BLUETTI Elite 100 V2 at up to 1,000W, compared with up to 600W for the Anker C1000 Gen 2.
Which is lighter or smaller?
They are nearly identical in weight — about 24.9lb for the Anker and 25.3lb for the BLUETTI. The BLUETTI has the more compact footprint at about 12.6 × 8.5 × 9.8 inches versus about 15.12 × 8.19 × 9.61 inches.
Can either be expanded with an extra battery?
No. Neither the Elite 100 V2 nor the C1000 Gen 2 supports adding battery capacity. If expansion is important, compare systems that do — the DELTA 3 Plus is one example.
Can both run a refrigerator or a microwave?
Yes for typical refrigerators and many household microwaves, provided the appliance's actual input wattage fits the rated output. Refrigerator runtime depends on average consumption, compressor cycling and ambient temperature.
Are both LiFePO₄?
Yes. Both use LiFePO₄/LFP chemistry rated at roughly 4,000 cycles to about 80% capacity.
Which is better for camping?
For short trips with mains recharging, the Anker's higher output and faster charging suit the routine. For multi-day off-grid trips relying on solar, the BLUETTI's 1,000W input ceiling and compact footprint are more useful.
