Runtime estimator
How long will it actually run?
Pick a unit, switch on what you'd plug in. We factor in an 85% real-world efficiency so the estimate is honest, not optimistic.

Technology
Six reasons this isn't just a big power bank.
56 min
0–100%
01X-Stream
Full in about an hour.
X-Stream charging pulls up to 1,500 W from a normal wall socket. A DELTA 3 goes from empty to full in 56 minutes; most RIVER units in 60–70. Charge between cuts, not overnight.
02UPS
Switches over before you notice.
Plug the router, PC or CPAP through the unit and it takes over in under 10 milliseconds when the mains drops. Nothing reboots. Nothing flickers.
03X-Boost
Runs the heavy stuff too.
X-Boost lets a 1,800 W unit drive appliances rated up to 2,600 W — mixers, kettles, irons, even a 1-ton AC — by intelligently trimming voltage under load.
04LFP
Built for ten years, not two.
Lithium iron phosphate cells rated for 3,000–4,000 full cycles before dropping to 80% capacity, watched over by a BMS that monitors voltage, current and temperature every second.
05Outlets
Everything plugs in at once.
Up to 13 outlets on a DELTA: four universal AC sockets, 140 W USB-C, USB-A, DC barrel and a car port. The whole desk, the whole kitchen counter, on one unit.
06Solar
Five ways to charge.
Wall, solar, car, generator — or wall and solar together for the fastest refill. Pair with a foldable 110–400 W panel and you're off-grid for the weekend.
Where it lives
Power for the way you actually live.

Questions
Straight answers on backup power
A portable power station is a sealed, plug-and-play unit: no wiring, no acid batteries, no installer. It sits on a shelf, recharges from any socket in about an hour, switches over in milliseconds and can go with you in the car.
