OSCAL is expanding its portable power lineup with a new model aimed at people who want reliable electricity at home, at a campsite, or during emergencies. The OSCAL PowerMax 1800 SE is built to deliver a strong mix of capacity, output power, and portability, making it a practical option for anyone preparing for outages or looking for off-grid energy without hauling around an oversized unit.
At the center of the PowerMax 1800 SE is a 1,024Wh battery paired with a 1,800W continuous pure sine wave output. In everyday terms, that means it’s designed to comfortably run many common devices and appliances you might need in real life: kitchen gear, laptops, power tools, and other electronics that benefit from stable, clean power. It also supports surges up to 2,400W, helping it handle brief startup spikes from certain equipment. Despite the performance, OSCAL positions it as relatively easy to move around at 15.5 kg, which can be a meaningful advantage if you expect to carry it between rooms, load it into a car, or bring it to job sites.
Charging flexibility is another major selling point. The PowerMax 1800 SE supports up to 800W solar input, and under very good conditions that can push the battery to around 80% in roughly an hour. For standard home charging, it includes a 700W fast-charge mode that can bring the unit to a full charge in about 90 minutes. Beyond basic wall charging, it also supports hybrid AC plus solar input, car charging, EV charging stations, generators, and even alternative sources such as wind or hydro setups, which broadens its appeal for both city living and off-grid use.
Durability and safety are clearly part of the pitch. The unit uses a third-generation UL-certified LFP (LiFePO4) battery rated for more than 3,500 charge cycles, a chemistry widely known for longevity and thermal stability. It also includes a 12-layer battery management system, a UL 94 V-0 fire-resistant casing, and an IP54 rating to help resist dust and splashes—useful traits for outdoor use, garages, and workshops.
For home backup, one of the most practical features is the built-in UPS function with a 0.01-second switchover time. That rapid response is designed to help keep critical electronics running during sudden outages, including routers, PCs, NAS systems, and certain medical devices—exactly the kind of gear people often want protected when the power blinks out unexpectedly.
Pricing is positioned as a value play. The OSCAL PowerMax 1800 SE carries an MSRP of $459.99 in the US, but a limited-time launch discount brings it down to $400 on Amazon when using coupon code 6486YEZ5. The code is stated to be valid through January 31, and as with most promotions, availability and pricing can change over time.
Note: The original post states this is a paid placement and that promotional pricing may be time-limited or subject to stock and retailer changes.
