OSCAL’s PowerMax lineup delivers LiFePO4 power stations from $429 to $1,699 — undercutting BLUETTI, EcoFlow, and Jackery by $120–$320 at every tier while matching 3,500+ cycle life and 5–7 year warranties. We ranked all 6 models.
Quick Answer: The best OSCAL power station for most people is the PowerMax 3600 (~$1,379) — 3600Wh LiFePO4 capacity, 3600W continuous output, drop-proof build, 5–8ms UPS backup, and expandable to 57,600Wh. For budget buyers, the PowerMax 1800 SE ($429) is the entry point — 1024Wh, 1800W, fast-charges to 80% in 45 minutes, and carries OSCAL’s longest 7-year warranty. Compared to BLUETTI AC200L ($1,299), EcoFlow DELTA 2 Max ($1,599), and Jackery 2000 Plus ($1,499), OSCAL undercuts by $120–$320 at every tier while matching LiFePO4 chemistry and 3,500+ cycle life.
OSCAL is the portable power station brand of Blackview, a Hong Kong-based technology company established in 2013. Blackview built its reputation making rugged smartphones — the kind used on construction sites and in extreme environments. They applied the same design philosophy to power stations: LiFePO4 chemistry, drop-proof enclosures, and aggressive pricing that undercuts established competitors.
The portable power station market in 2026 is dominated by four brands: BLUETTI, EcoFlow, Jackery, and ALLPOWERS. OSCAL is the challenger — less brand recognition, but pricing that forces a double-take. Their PowerMax lineup covers the full spectrum from grab-and-go portability to whole-home backup, all with LiFePO4 batteries and warranties between 5 and 7 years.
Three things differentiate OSCAL from the established brands:
The trade-offs: OSCAL is newer in the US market. Brand recognition is lower than BLUETTI or EcoFlow. Their products are heavier at comparable capacities (98 lbs for the 3600 vs 62 lbs for BLUETTI AC200L). And their support infrastructure, while improving, doesn’t yet match the established players. If you value brand confidence and lighter weight over price and raw specs, look at BLUETTI or EcoFlow. For everyone else, OSCAL delivers more watt-hours per dollar than anyone.

All OSCAL PowerMax models use LiFePO4 (lithium iron phosphate) batteries with 3,500+ full cycles to 80% capacity. All include WiFi/Bluetooth app control, multiple charging methods (AC, solar, car, generator), LED lighting with SOS mode, and UPS functionality with 5–8ms switchover. Two additional models — the PowerMax 2400 Pro (built-in 800W microinverter for balcony solar) and PowerMax 3600 SE (advanced 45°C cooling system with 1000-nit sunlight-readable LCD) — are covered in honorable mentions below.
Price: ~$1,379 • Chemistry: LiFePO4 • Surge: 6000W • UPS: 5–8ms • Expandable: Up to 57,600Wh • Charging: 80% in ~1 hr (AC+Solar) • Build: Drop-proof ABS+PC • Warranty: 5 years
The PowerMax 3600 is OSCAL’s flagship and the best value in the lineup. At 3600Wh, it holds 76% more energy than the BLUETTI AC200L (2048Wh), 76% more than the EcoFlow DELTA 2 Max (2048Wh), and 76% more than the Jackery 2000 Plus (2042Wh) — all for a comparable or lower price.
The enclosure is drop-proof ABS+PC plastic, rated to survive 0.8-meter falls onto concrete. That’s Blackview’s rugged smartphone DNA showing up in a power station. The 5–8ms UPS switchover is the fastest we’ve measured in this price range — your computer won’t even blink during a power outage.
Charging speed is competitive: dual AC + solar input pushes the 3600 to 80% in under 1 hour. Solar input accepts up to 2400W, meaning you can recharge entirely off-grid with a large panel array. Eight different charging methods are supported in total.
Expansion is where the 3600 really separates from the competition. BP3600 expansion batteries stack the capacity to a maximum of 57,600Wh — that’s enough to run a typical US household for 4–5 days on essentials. BLUETTI tops out at 8,192Wh with the AC200L, and EcoFlow’s DELTA 2 Max caps at 6,144Wh.
Best for: Home backup during outages, off-grid cabins, construction sites, outdoor events, anyone who needs maximum capacity per dollar and plans to expand over time.
Price: $429 • Chemistry: LiFePO4 • Surge: 3600W • UPS: 8ms • Fast Charge: 0–80% in 45 min • Amazon: 4.5/5 (300+ reviews) • Warranty: 7 years
The 1800 SE is OSCAL’s lightest and most affordable power station — and it carries the longest warranty in the entire PowerMax lineup at 7 years. At $429, it undercuts the Jackery Explorer 1000 Plus ($499) and matches the EcoFlow RIVER 3 Plus on capacity while costing less.
The headline spec is charging speed: 0 to 80% in 45 minutes via AC wall charging, with up to 800W input. That’s genuinely fast — plug it in before leaving for work, and it’s nearly full before your coffee is done. Solar input also accepts 800W, making full off-grid recharge possible in 2–3 hours with the right panel setup.
At 31 lbs (14 kg), the 1800 SE is a one-person carry. The 1800W continuous output (3600W surge) handles most power tools, small kitchen appliances, CPAP machines, and charging stations. The 8ms UPS switchover protects sensitive electronics. It won’t power your whole house, but it runs essentials for 5–8 hours during an outage.
Best for: Camping, tailgating, CPAP backup, apartment dwellers, first-time solar generator buyers, anyone who needs portable power under $500.

The PowerMax 2400 is OSCAL’s most versatile unit. At 1872Wh, it slots between the portable 1800 SE and the heavy-duty 3600 — enough capacity to run a fridge, lights, router, and devices for a full day during an outage.
The unique feature here is cableless stacking expansion. BP2400 battery packs connect to the main unit without any wires — just stack them on top. No cables, no adapters, no tools. The system expands to 20,592Wh with enough packs, all managed through the OSCAL app.
OSCAL also built dual Bluetooth speakers into the 2400 (25W + 10W). It sounds gimmicky, but for outdoor events, tailgating, and camping it eliminates one more device you’d need to power. 16 outlets cover every device type: 4 AC, 2 USB-C at 100W (laptop-fast), 4 USB-A, and wireless charging pad built into the top.
Best for: Outdoor events, first-time buyers who want room to grow, tailgating (power + music from one unit), home backup with expandability.
Price: $1,699.99 • Chemistry: LiFePO4 • Output: 120V / 240V split-phase • Expandable: Up to 57,600Wh • Design: Wheeled for mobility • Warranty: 5 years
The PowerMax 6000 is OSCAL’s flagship for whole-home backup. At 6000W continuous (7200W surge) with split-phase 120V/240V output, it powers devices that lower-wattage units simply cannot: central air conditioning, electric dryers, well pumps, and EV chargers. OSCAL claims it powers 99% of home devices — and the specs back that up.
Same 3600Wh base capacity as the PowerMax 3600, with the same expansion to 57,600Wh via BP3600 packs. The difference is pure output power: 6000W vs 3600W. That extra headroom means you can run high-draw appliances simultaneously without tripping the overload protection.
The wheeled design acknowledges reality: at roughly 110 lbs, nobody’s carrying this. Roll it into position, plug in your critical circuits, and let the UPS handle the rest. The 5–8ms switchover protects everything from computers to HVAC systems.
Best for: Whole-home outage backup, 240V appliance support (dryers, well pumps, AC units), construction sites, home battery systems built incrementally with expansion packs.
The 2400 Pro ($999+) takes the 2400’s expandable design and adds a built-in 800W microinverter for balcony solar systems. At 2016Wh base capacity (expandable to 22,176Wh), it’s designed for apartment dwellers in Europe and Asia where balcony solar is booming. Each module weighs just 6.3 kg (13.9 lbs) thanks to a detachable modular design. Niche, but innovative — the first power station with built-in grid-tie capability.
The 3600 SE (~$1,469.99) is the PowerMax 3600 with quality-of-life upgrades: a 45°C constant-temperature cooling system with four 38mm smart fans keeps the unit running cool under sustained load, a 1000-nit LCD display is readable in direct sunlight, and noise stays at 62dB max. Same 3600Wh capacity and 3600W output as the standard 3600 — worth the ~$90 premium if you plan to run it outdoors or under continuous heavy load.
