A power outage during movie night, a camping trip with no outlet in sight, or a balcony solar power system whose solar energy goes to waste in the evening—there’s an elegant solution for all these situations: a portable power station. The manufacturer OSCAL, already known to many for its rugged outdoor smartphones, has established itself in the mobile energy storage market with its PowerMax series. And right now, great technology meets a truly great price: Both the OSCAL PowerMax 1800SE and the larger PowerMax 3600PE are currently heavily discounted. We’ve taken a look at both models and will show you which one is worth it for whom.
Through August 30, 2026, you can snag both power stations at a hefty discount:
Why get a power station in the first place?
At its core, a power station is a large battery with smart electronics: It stores electricity and dispenses it via standard Schuko outlets, USB ports, and 12-volt outputs—silently, emission-free, and without gasoline. It thus replaces the traditional, noisy generator and covers several use cases at once: emergency power during blackouts, power while camping or in a RV, electricity on construction sites, and—in combination with solar panels—a mobile solar generator that charges itself independently from the sun.
Modern devices like the OSCAL models rely on LiFePO4 battery cells (lithium iron phosphate). This technology is considered particularly durable and safe: it offers several thousand charge cycles, a low fire risk, and a service life that can easily reach 15 years with daily use. This is precisely where it differs from many cheap power stations with conventional lithium-ion cells.
OSCAL PowerMax 1800SE: The Versatile All-Rounder
The OSCAL PowerMax 1800SE is the more compact of the two models—yet it’s a true powerhouse. It boasts a capacity of 1024 Wh and delivers 1800 watts of continuous power with a peak output of up to 3600 watts. This means it can power not only laptops, routers, and lamps, but also power-hungry devices like kettles, coffee makers, drills, or a small refrigerator.
The UPS (uninterruptible power supply) function is particularly handy: If the mains power fails, the unit switches to battery power in just 8 milliseconds—fast enough that your PC, NAS, or freezer won’t notice a single interruption.
The 1800SE is also quick when charging. With an AC charging power of around 700 watts, the battery goes from 0 to 80 percent in about an hour. If you connect solar panels, you can charge with up to 800 watts of solar input and fully charge the station in about 1.5 hours under good sunlight—ideal for off-grid use.
Key specifications of the PowerMax 1800SE at a glance:
- Capacity: 1024 Wh, LiFePO4 battery (expandable)
- Power: 1,800 W continuous, 3,600 W peak
- Connections: 11 outputs, including 3 AC outlets, 2× USB-A, 2× USB-C (PD, up to 100 W), 2× DC5521, and a car charger port
- UPS switchover time: 8 ms
- Charge cycles: Over 3,500 cycles to ~80% remaining capacity, approximately 15-year service life
- Weight: approx. 14 kg
- Warranty: 5 years
The Offer: Instead of the regular price of €1,188, the PowerMax 1800SE is available during the promotional period for just €307.75 with the code DELD45—a discount of about 74 percent. The offer is valid from July 28 through August 30, 2026.
OSCAL PowerMax 3600PE: The Power Plant for the Whole House
If you need more capacity—for example, for longer power outages, energy-intensive tools, or as the centerpiece of a balcony power plant expansion—the OSCAL PowerMax 3600PE is the right choice. With 2,016 Wh, this upgraded version offers twice the capacity of the 1800SE and delivers a solid 3,600 watts of continuous power with a peak output of up to 7,200 watts. This allows you to run even several large appliances at the same time.
The battery is based on high-quality, automotive-grade LiFePO4 cells designed for over 6,000 charge cycles and a service life of more than 15 years—a figure that qualifies the station for even intensive, continuous use. Despite its large capacity, it remains portable: Integrated casters and an extendable telescoping handle make the station, which weighs about 24 kg, as easy to move as a suitcase.
There’s no shortage of ports: It features 14 outputs, including four pure sine wave AC outlets, four USB-A fast-charging ports, two USB-C ports, a 12-V car outlet, and two DC5521 jacks. Charging is possible via AC power at up to 1,500 watts (0–80% in about 60 minutes) or via solar at up to 1,600 watts. The 3600PE also offers fast EPS/UPS switching in 8 milliseconds.
Key specifications of the PowerMax 3600PE at a glance:
- Capacity: 2,016 Wh, LiFePO4 battery (automotive grade)
- Power: 3,600 W continuous, 7,200 W peak
- Connections: 14 outputs, including 4 AC outlets (pure sine wave), 4× USB-A, 2× USB-C, car outlet, 2× DC5521
- Charging: up to 1,500 W AC (0–80% in ~60 min), up to 1,600 W solar
- Switching time: 8 ms (EPS)
- Charge cycles: Over 6,000 cycles, more than 15 years of service life
- Weight: approx. 24 kg, with wheels and telescoping handle
The Deal: The regular price of €2,244 drops to €695.64 with the code DELD63—a savings of about 69 percent. This offer also runs from July 28 through August 30, 2026.
Which model is right for whom?
The PowerMax 1800SE is the right choice if portability and an affordable entry-level option are your top priorities. Weighing just 14 kilograms, it’s still easy to carry and fits easily in a car or RV. It’s perfectly sized for camping weekends, as an emergency power reserve for essential devices, or for charging laptops, camera gear, and small kitchen appliances.
The PowerMax 3600PE is designed for anyone who needs true endurance and high performance. Its double capacity bridges longer power outages, powers tools on construction sites, and serves as a stationary energy storage solution—for example, in combination with a balcony power plant, allowing solar power to be temporarily stored for use in the evening. Those who regularly run larger power-consuming devices are much better off with the 3,600-watt continuous power output.
As a rule of thumb: The 1800SE is sufficient for occasional outdoor use and smaller devices. Those who want to power their home or perform energy-intensive work are better off with the 3600PE—and, with the current offer, benefit from a better price-per-watt-hour ratio.
