Portable power stations have moved from niche camping gear to everyday essentials. Whether you are preparing for storm season, planning an off-grid weekend, or just tired of hunting for the one working outlet at the campsite, a reliable power station changes the game. OSCAL's PowerMax lineup spans from a compact 1024Wh unit you can carry with one hand to a 6000W beast that backs up your entire home. This guide walks you through all six models so you can pick the right one without guesswork.

PowerMax 1800 SE: The Lightweight Workhorse
At roughly 14 kg with 1024Wh capacity, the PowerMax 1800 SE is the grab-and-go option. 1800W rated output with 3600W surge handles 99% of household appliances from coffee makers to power tools. A 700W AC input charges 0% to 80% in about one hour. Solar input supports up to 800W for a full charge in roughly 1.5 hours under good sun.
Ten output ports (3 AC, 2 USB-C 100W PD, 2 USB-A, 2 DC5521, 1 car outlet) cover a small team's devices. The 0.01s UPS switchover keeps routers and computers running through outages without a blink. Backed by a 7-year warranty.
Best for: Camping, job sites, emergency backup for essential devices, anyone who values grab-and-go portability.
PowerMax 2400: The Cableless Stacking Performer
The PowerMax 2400 packs 1872Wh base capacity with 2400W output (4800W surge) and an innovative cableless stacking design that expands to 20,592Wh with additional BP2400 battery packs. No tangled cables, just stack and snap.
Its 25W subwoofer and 10W tweeter deliver 130dB sound for outdoor movie nights, campfire music, or emergency signaling. Sixteen outputs include 4 AC outlets, 2 USB-C 100W, 4 USB-A, wireless charging pads, and an Anderson connector. AC fast charging hits 80% in 1.2 hours at 1500W. Solar input tops 800W. The 0.01s UPS auto-switch keeps sensitive gear safe during grid drops.
Best for: RV and van life, home backup with expandable capacity, outdoor entertainment, users who want clean cable-free stacking.
PowerMax 2400 Pro: The Balcony Solar Specialist
The PowerMax 2400 Pro takes the 2400 platform and adds a built-in 800W microinverter for balcony solar systems. With 2016Wh base capacity expandable to 22,176Wh via cableless stacking, it doubles as a grid-tied energy system. Sell surplus power back to the grid during peak rates, use stored energy when electricity is expensive.
The same 25W+10W dual speaker system and 130dB output carry over from the 2400. Each module weighs just 6.3 kg thanks to the detachable design. A 2-in-1 on-grid/off-grid architecture means it serves as both backup power and daily energy savings.
Best for: Apartment dwellers with balconies, homeowners wanting to cut electricity bills, eco-conscious users who want grid-tied solar without complex installation.
PowerMax 3600: The Rugged Workhorse
The PowerMax 3600 was OSCAL's first rugged power station, borrowing durability DNA from the company's rugged phone lineup. With 3600Wh (expandable to 57,600Wh) and 3600W output (EU) / 3000W (US), it handles heavy loads for days.
A built-in advanced TI chip delivers up to 10% faster processing. The 0.8m drop-proof ABS+PC enclosure carries UL94V-0 flame-retardant rating, splash-proofing, and dust-proofing. Operating range spans -20°C to 55°C. Five LED light modes include Morse code signaling for emergencies. Fourteen outputs cover every device type. Dual charging (AC + solar) hits 80% in 0.96 hours. The 5-8ms UPS switchover is 50% faster than competitors.
Best for: Extreme outdoor work, disaster response, remote cabins, users who need military-grade durability in a power station.
PowerMax 3600 SE: The Smart Home Anchor
The PowerMax 3600 SE shares the 3600's core specs (3600Wh, 3600W/3000W, expandable to 57,600Wh) with refined smart features. The upgraded app and firmware deliver faster response times. A 45°C constant-temperature cooling system with four 38mm smart fans reduces internal temperature by up to 40°C. The 1000-nit LCD display stays readable in direct sunlight.
Fourteen versatile outlets, 5-8ms UPS, and whisper-quiet operation at 62dB max make it ideal for home backup where noise matters. The 2200W AC input charges from empty in 1.96 hours.
Best for: Whole-home backup for multiple circuits, home offices that cannot afford downtime, powering medical equipment, extended off-grid living.
PowerMax 6000: Whole-Home, No Compromise
The PowerMax 6000 is the flagship. With 6000W continuous output and 7200W surge, it handles heavy-duty appliances that smaller units cannot touch: well pumps, electric water heaters, air conditioners, and large power tools. Dual-voltage 120V/240V split-phase output means it can power an entire electrical panel.
The expandable battery system scales from 3600Wh to 57,600Wh with additional battery packs. Fourteen output ports, a 5-8ms UPS, and a wheeled design make it the definitive choice for whole-home backup or serious off-grid work. Built like a tank with drop-proof, splash-proof, and dust-proof enclosure rated for -20°C to 55°C operation.
Best for: Whole-home backup, construction sites, large RVs, off-grid cabins, anyone who cannot afford to lose power.
How to Decide: Three Questions
1. What do you need to power?
Make a list. Phone and laptop? The 1800 SE is plenty. Refrigerator plus lights and internet? The 2400 or 2400 Pro. A full-size refrigerator, freezer, and well pump? Step up to the 3600 series. Air conditioner or electric water heater? Only the 6000.
2. How long do you need power?
Capacity determines runtime. A 1024Wh unit runs a 60W laptop for roughly 16 hours. A 3600Wh unit runs the same laptop for 60 hours, or a 200W refrigerator for 15-18 hours. The 2400, 2400 Pro, and 3600 series all support expansion for multi-day coverage.
3. Will you move it often?
The 1800 SE at 14 kg is genuinely portable. The 2400 at 25.5 kg is manageable with two hands. The 2400 Pro's per-module weight of 6.3 kg makes it the easiest to move piece by piece. The 3600 series at 44.5 kg and the 6000 at 50 kg have wheels for good reason.
Solar Charging: The Free Fuel
Every PowerMax model supports solar input. OSCAL's foldable solar panels connect directly to the power station. In full sun, a 400W panel array charges the 1800 SE in under 3 hours. The 2400 Pro's built-in microinverter makes balcony solar plug-and-play. Solar turns your power station from a battery into a self-sustaining energy system.
The Bottom Line
OSCAL's PowerMax lineup covers the full spectrum: grab-and-go portability (1800 SE), cableless expandability with dual speakers (2400), balcony solar integration (2400 Pro), rugged durability (3600), refined smart home backup (3600 SE), and whole-home dominance (6000). All six run on LiFePO4 chemistry, support solar charging, include smart app control, and carry at minimum a 5-year warranty.
For most households, the 2400 or 2400 Pro hits the sweet spot of capacity, features, and price. For serious backup with expandability, the 3600 series delivers pro-grade reliability. And if your home or work cannot tolerate a single minute of downtime, the 6000 is the only call.
