Dabbsson DBS3500 Portable Power Station
The Dabbsson DBS3500 Portable Power Station is a 3430Wh LiFePO4 power station with 3600W of pure sine wave 120V AC output (7200W surge), built for home backup, off-grid use and job sites that need to run large appliances. It expands to 14,070Wh with two Dabbsson DBS5300B batteries, and its battery is rated for 4,000 cycles to 80% capacity. It weighs 90.5 lbs (41 kg) and rolls on wheels with a pull handle.
3430Wh LiFePO4 Battery Rated for 4,000 Cycles
The Dabbsson DBS3500 stores 3430Wh in a 51.2V, 67Ah lithium iron phosphate (LiFePO4) pack rated for 4,000 cycles before capacity drops to 80%. The battery management system covers over-voltage, over-charge, overload, overcurrent, short-circuit, low-voltage, high-temperature and low-temperature protection.
3600W AC Output and 16 Ports
Five pure sine wave 120V AC outlets share 3600W, with a 7200W surge for motor startups. The DBS3500 also has three USB-C ports (two at 100W, one at 30W), three USB-A ports (two 18W fast charge, one 12W), a 126W car outlet, two DC5521 ports and two Anderson outputs (12.6V 30A and 24V 15A).
Recharge at Up to 1800W AC, 2400W Solar or 3400W Combined
From a wall outlet, the Dabbsson DBS3500 accepts up to 1800W at 120V, with an adjustable AC charge rate of 200W to 1800W (600W by default). Its solar input takes 12-150V, 25A and up to 2400W from MC4 panels, and combined AC + solar input reaches 3400W. A 12V/24V car charging input (8A by default) is also available.
Expand From 3430Wh to 28,140Wh
One Dabbsson DBS5300B Expandable Battery brings the DBS3500 to 8750Wh, and two bring it to 14,070Wh. Two DBS3500 units linked with a parallel connector (sold separately) deliver 240V and 7000W from 6860Wh, and with four DBS5300B batteries the system reaches 28,140Wh.
15ms Emergency Power Supply for Home Backup
When the Dabbsson DBS3500 is plugged into the grid, connected devices run on grid power through the unit. If the grid fails, it switches to battery power within 15ms. Dabbsson notes that this basic UPS function does not offer 0ms switching, so it should not be used for data servers or workstations that require it.
App Control Over Wi-Fi and Bluetooth
The Dabbsson app connects over 2.4GHz Wi-Fi and Bluetooth to show input, output and battery level, set the AC charge rate, schedule timers and install firmware updates.
Pull Handle and Wheels at 90.5 lbs
At 20.9 x 12 x 15.4 in (533 x 305 x 393 mm) and 90.5 lbs (41 kg), the Dabbsson DBS3500 moves on two wheels with a pull handle. It operates between 32°F and 104°F (0°C to 40°C).
