The Bluetti AC180 and Anker Solix C1000 target the same buyer: someone who wants a capable 1000Wh-class station without spending over $1,000. They differ in capacity, weight, expandability, and price. Here is how they compare.
Specs at a Glance
| Spec | AC180 | Solix C1000 | |------|-------|-------------| | Capacity | 1,152Wh | 1,056Wh | | Output | 1,800W (2,700W lift) | 1,800W (2,400W surge) | | Weight | 35.3 lbs | 30.9 lbs | | AC Charge | ~75 minutes | ~58 minutes | | Solar Input | Up to 500W | Up to 600W | | Battery | LFP, 3,500+ cycles | LFP, 3,000+ cycles | | Expandable | No | Yes (with BP1000) | | Price | $699 | $649 |
Capacity vs Value
The AC180 packs 1,152Wh versus the C1000's 1,056Wh. That is about 9% more capacity. At $699 vs $649, the AC180 costs $50 more but delivers nearly 100Wh extra. In watt-hours per dollar, the AC180 wins: 1.65Wh/$1 vs 1.63Wh/$1. Not a massive gap, but the Bluetti gives you more battery.
Expandability
The Solix C1000 supports the Anker BP1000 expansion battery, doubling capacity to 2,112Wh. The AC180 is standalone. If you might need more capacity in the future, the Anker offers a growth path that Bluetti does not.
Portability
At 30.9 lbs, the Solix C1000 is 4.4 lbs lighter than the AC180 (35.3 lbs). Both are one-person carries, but the Anker is noticeably easier to move. For frequent movers, this matters.
Charging and Solar
The Solix C1000 charges slightly faster via AC (58 min vs 75 min) and accepts more solar input (600W vs 500W). The AC180's charging is still fast enough for most use cases, but the Anker has the edge here.
Which Should You Buy?
Choose the AC180 if:
- You want the most capacity for your money
- 1,152Wh is enough for your needs (no expansion needed)
- Budget is your primary decision factor
- You prioritize Bluetti's Power Lifting for resistive loads
Choose the Solix C1000 if:
- You want the option to expand capacity later
- Lighter weight matters for your use case
- You prefer faster AC and solar charging
- You trust Anker's ecosystem and app experience
Both are strong picks. The AC180 wins on raw value. The C1000 wins on portability and future-proofing.
