The short answer
We compared the current power stations we track for both brands (17 Bluetti, 9 Anker SOLIX). Buy Anker SOLIX when output and charging decide it: median AC output is 2,400 W against 1,800 W, the F3800 reaches 6,000 W, and the F3000 and F3800 accept 2,400 W of solar against a 1,200 W ceiling on Bluetti. Buy Bluetti when cycle life decides it: median rated cycles are 3,500 against Anker’s flat 3,000, and three models are rated 6,000. Under 1,600 Wh both brands offer a range: the figures here count ten Bluetti units and four Anker units, but Anker also sells the AC-equipped SOLIX C300, the C800 and the C1000 Gen 2. Price per Wh depends on size: Anker’s median is lower overall ($0.47 against $0.515), Bluetti’s is lower from 1,000 Wh up ($0.445 against $0.46), and both brands have a 5-year median warranty.
How to read this. Figures are manufacturer specifications and list prices; we have not tested any of these products. Medians leave out any model we have no figure for. Anker’s C200 DC and C300 DC are DC-only with no AC outlets, so they have no AC output rating and are left out of the AC-output median. Per-unit prices appear only for models without Amazon links.

The two line-ups in numbers
| Measure | Bluetti | Anker SOLIX |
|---|---|---|
| Power stations compared | 17 | 9 |
| Median $/Wh, all units | $0.515 | $0.47 |
| Median $/Wh, 1,000 Wh and up | $0.445 | $0.46 |
| Median capacity | 1,152 Wh | 2,048 Wh |
| Largest unit | 3,840 Wh | 3,840 Wh |
| Median AC output | 1,800 W | 2,400 W |
| LiFePO4 share | 94% (16 of 17) | 100% (9 of 9) |
| Median rated cycles | 3,500 | 3,000 |
| Median warranty | 5 years | 5 years |
| Median solar input | 500 W | 800 W |
| Median AC charge | 1,440 W | 1,800 W |
| Expandable models | 2 of 17 | 6 of 9 |
Two Bluetti products skew these figures: a two-pack of the Elite 10 Mini counts as one unit ($1.86 per Wh), and the Premium 200 V2 is left out of the capacity and price-per-Wh medians. On the Anker side, the C200 DC (192 Wh) and C300 DC (288 Wh) are DC-only, so they carry no AC rating and sit outside the AC-output median, which covers Anker’s seven AC models. They stay in the other medians; dropping them would move Anker’s median price per Wh from $0.47 to $0.46 and its median weight from 27.2 to 29.8 lb per kWh. The expandable counts are our own tally: the AC200L and Apex 300 for Bluetti, six units for Anker; the last question covers the expansion batteries.
Size-by-size match-ups
Each bracket pairs the closest models by capacity that have published specs.
Under 700 Wh
| Spec | BLUETTI Elite 30 V2 | Anker 521 PowerHouse |
|---|---|---|
| Capacity | 288 Wh | 256 Wh |
| AC output | 600 W | 200 W |
| Surge | 1,500 W | 600 W |
| Rated cycles | 3,000 | 3,000 |
| Warranty | 5 years | 5 years |
| Solar input | 200 W | 65 W |
| AC charge | 380 W | 125 W |
| Weight | 9.5 lb | 8.2 lb |
| Price per Wh | $0.83 | $1.02 |
The Elite 30 V2 stores 12.5% more (288 against 256 Wh), has three times the AC output, 2.5 times the surge and about three times the solar input, and costs less per Wh; the 521 PowerHouse is 1.3 lb lighter. BLUETTI lists 380 W of AC charging for the Elite 30 V2, and 80% in 45 minutes at 77°F (spec page checked October 2026), against Anker’s 125 W for the 521 PowerHouse. Bluetti reaches further up the bracket with the AC50B (448 Wh, 700 W). Anker’s C200 DC and C300 DC have no AC outlets, so they are not alternatives for anything that plugs into a wall outlet. Anker also sells an AC version of the SOLIX C300: Anker lists 288 Wh, 300 W and 600 W surge, so it matches the Elite 30 V2’s capacity with half its AC output.
700 to 1,600 Wh
| Spec | BLUETTI Elite 100 V2 | Anker SOLIX C1000 |
|---|---|---|
| Capacity | 1,024 Wh | 1,056 Wh |
| AC output | 1,800 W | 1,800 W |
| Surge | 2,700 W | 2,400 W |
| Rated cycles | 4,000 | 3,000 |
| Warranty | 5 years | 5 years |
| Solar input | 1,000 W | 600 W |
| AC charge | 1,200 W | 1,300 W |
| Weight | 25 lb | 28.44 lb |
The closest pair here: 1,024 against 1,056 Wh, both at 1,800 W. Bluetti takes 1,000 W of solar against 600 W, is rated 4,000 cycles against 3,000, and weighs 3.4 lb less; Anker charges faster from a wall outlet (1,300 W against 1,200 W) and stores 3% more. Bluetti has five more models in this bracket, including the AC180 (1,152 Wh, 1,440 W AC charge, $0.39 per Wh). Anker also sells the SOLIX C800 (768 Wh, 1,200 W) and the C1000 Gen 2 (1,024 Wh, 2,000 W), which are not in the figures above; the C1000 Gen 2 is the closer match for the Elite 100 V2’s 1,024 Wh. Related: AC180 vs AC180P vs AC180T and Elite 100 V2 vs Elite 200 V2.
1,600 to 3,000 Wh
| Spec | BLUETTI Elite 200 V2 | Anker SOLIX C2000 Gen 2 |
|---|---|---|
| Capacity | 2,074 Wh | 2,048 Wh |
| AC output | 2,600 W | 2,400 W |
| Surge | 3,900 W | 4,000 W |
| Rated cycles | 6,000 | 3,000 |
| Warranty | 5 years | 5 years |
| Solar input | 1,000 W | 800 W |
| AC charge | 1,800 W | 1,800 W |
| Weight | 53.4 lb | 41 lb |
Bluetti doubles the cycle rating and adds 200 W of solar; Anker is 12.4 lb lighter and has the higher surge. Bluetti’s AC200L matches the C2000 Gen 2 on 2,048 Wh and 2,400 W with more solar (1,200 W) and AC charge (2,400 W), but weighs 62.4 lb. One tier up, Anker’s F2600 (2,560 Wh, 2,400 W, $0.39 per Wh) meets Bluetti’s Apex 300 (2,765 Wh, 3,840 W, 6,000 cycles, $0.69 per Wh): the Apex 300 adds 1,440 W of output at about 1.8 times the price per Wh.
Over 3,000 Wh (home-backup class)
| Spec | BLUETTI Elite 300 | Anker SOLIX F3000 |
|---|---|---|
| Capacity | 3,014 Wh | 3,072 Wh |
| AC output | 2,400 W | 3,600 W |
| Surge | 4,800 W | 7,200 W |
| Rated cycles | 6,000 | 3,000 |
| Warranty | 5 years | 5 years |
| Solar input | 1,200 W | 2,400 W |
| AC charge | 1,800 W | 3,600 W |
| Weight | 58 lb | 91.5 lb |
Anker gives 50% more output and double the solar input and AC charge, at 33.5 lb more weight and half the cycle rating. At the top, the F3800 offers 3,840 Wh, 6,000 W and a 9,000 W surge (132.3 lb). Bluetti’s Elite 400 matches the 3,840 Wh, at $0.34 per Wh, and BLUETTI lists 2,600 W of AC output for it (product page checked October 2026), against the F3800’s 6,000 W.

Where each brand wins and where it loses
Bluetti wins, Anker SOLIX loses
- Cycle life. The median is 3,500 against 3,000. Elite 200 V2, Apex 300 and Elite 300 are rated 6,000; none of Anker’s nine is above 3,000. At one cycle a day that is about 16.4 against 8.2 years (cycles divided by 365), though the ratings quoted here do not say what remaining capacity counts as worn out.
- Weight in the 1 kWh and 3 kWh pairs. The Elite 300 is 58 lb against the F3000’s 91.5 lb (19.2 against 29.8 lb per kWh), and the Elite 100 V2 is 25 lb against the C1000’s 28.44 lb.
- Price per Wh at the top. Elite 400 $0.34 and Elite 300 $0.36; Anker’s lowest is the F2600 at $0.39.
Anker SOLIX wins, Bluetti loses
- Output. Median 2,400 W against 1,800 W. The F3800 delivers 6,000 W with a 9,000 W surge; Bluetti’s best is the Apex 300 at 3,840 W and 7,680 W.
- Charging. Solar input reaches 2,400 W against Bluetti’s 1,200 W, and AC charge reaches 3,600 W (F3000) against 2,400 W (AC200L and AC200P L).
- Uniform specs. All nine units are LiFePO4 on 5-year warranties. Bluetti has 3-year warranties on the Elite 10 Mini (single and two-pack) and the Pioneer Na, and the Pioneer Na uses sodium-ion cells rather than LiFePO4.
- Weight in the small and 2 kWh pairs. The C2000 Gen 2 is 41 lb against 53.4 lb, and the 521 PowerHouse 8.2 lb against 9.5 lb (256 Wh against 288 Wh). Across the line-ups the lead is thin: median weight is 29.8 lb per kWh for Anker’s seven AC units against 30.5 for Bluetti, about 2% apart. Anker’s figure drops to 27.2 once the two DC-only units, at about 21 to 22 lb per kWh, are counted.
- Overall price per Wh. $0.47 against $0.515, though the gap comes entirely from Bluetti’s small units (see the first question below).
They tie on median warranty (5 years), largest capacity (3,840 Wh) and, from 1,000 Wh up, price per Wh within about 3%.
Who should buy which
- Phone, laptop or CPAP. The Elite 30 V2 if anything you plug in draws over 200 W (it outputs 600 W); Anker’s 521 PowerHouse if the load stays under 200 W and 1.3 lb matters. Anker’s C200 DC and C300 DC have no AC outlets, so they do not suit wall-plug devices; the AC version of the C300 (300 W) does. Find the draw in How Many Watts Does a CPAP Use?, then divide 288 Wh (Elite 30 V2) or 256 Wh (521 PowerHouse) by it for a best-case runtime.
- A fridge or mid-size backup. The Elite 100 V2 and AC180 list 2,700 W of surge against the C1000’s 2,400 W. How Many Watts Does a Refrigerator Use? gives the draw; What Size Power Station Do I Need? covers capacity.
- RV, off-grid or a big solar array. The F3000 and F3800 accept double Bluetti’s best solar input. Start with Off-Grid and RV Power Setups and How to Size a Solar System.
- Heavy appliances and home backup. The Anker SOLIX F3800 has the most output (6,000 W, shared with the F3800 Plus); the Apex 300 is Bluetti’s strongest (3,840 W). See Home Battery Backup for sizing and costs.
- Long service life. Elite 200 V2, Apex 300 or Elite 300, all rated 6,000 cycles; LiFePO4 Portable Power Stations explains the chemistry.
- Cheapest per Wh in a big unit. Bluetti’s Elite 300 or Elite 400, or Anker’s F2600. Check live prices in the Power Station Price Index.
Common questions
Is Bluetti or Anker SOLIX cheaper per watt-hour?
Anker overall, at a median $0.47 against $0.515. The gap comes from size mix: Bluetti’s five single models under 1,000 Wh have a median of $0.89 per Wh (two-pack excluded). From 1,000 Wh up the medians are $0.445 for Bluetti and $0.46 for Anker. List prices move often, so recompute when you buy.
Which brand’s batteries last longer?
On rated cycles, Bluetti: a 3,500 median against 3,000 on all nine Anker units. These are manufacturer ratings we have not verified, and with a 5-year median warranty on both, the cycle rating is the main lifespan difference on paper; the Elite 10 Mini (single and two-pack) and the Pioneer Na carry 3-year warranties.
Can either brand be expanded with extra batteries?
Both. We count six expandable Anker units (C1000, C2000 Gen 2, F2600, F3000, F3800, F3800 Plus), though the only current Anker expansion battery we track is the BP2000 (Gen 2). On the Bluetti side we count two, the AC200L and Apex 300, and the current B300K and B500K batteries are named for those same two. Confirm compatibility on the maker’s page.
Which charges faster?
On wattage, Anker: median AC charge 1,800 W against 1,440 W, peak 3,600 W against 2,400 W. The mid-size pair is close at 1,300 W against 1,200 W; capacity divided by charge watts gives a best case of about 49 minutes for the C1000 and 51 for the Elite 100 V2. The makers’ own figures are slower: Anker quotes 58 minutes to 100% for the C1000 (product page checked October 2026), and BLUETTI quotes 70 minutes to full for the Elite 100 V2.
