The AIMS Power 5.04kWh Portable Power Station (AIO-5KWH4KW) is an all-in-one solar generator built around a 5040Wh LiFePO4 prismatic battery and a 4000W pure sine inverter. It supplies 100 to 120VAC at 60 Hz with 4000W (33 amps) of continuous output and 7000W of peak power, and it accepts up to 2100W of solar input and up to 1800W of wall charging.
It's built for tradespeople, installers and homeowners who want off-grid and emergency power without gas, fumes or noise. It accepts one optional AIO-5KWHBAT battery pack for more capacity, and 9-inch wheels with a folding handle make the 150 lb unit practical to move between job sites, campsites and emergency locations.
The battery is rated at 5040Wh and 51.2VDC, using lithium iron phosphate prismatic cells for long service life and stable energy output. That capacity lets you run power tools, appliances and backup loads for longer before you need to recharge, and the LCD shows battery level, input and output power, and remaining run time.
The end of the unit has an extended power pack connector for one optional 5040Wh AIO-5KWHBAT battery pack, which AIMS says raises total capacity up to 10,000 watt-hours. AIMS's manual notes that this optional battery works with the AIO-5KWH4KW only, connects with its own battery pack cable and should be connected with both units turned off.
The pure sine, high frequency inverter delivers 4000W (33 amps AC) continuously and 7000W (58 amps) at peak. AIMS names jackhammers, grinders, refrigerators and microwaves as the kinds of demanding loads it supports, and its estimates put a diamond core drill at 1800W and a jackhammer at 1350W.
The Anderson type solar input accepts 12 to 150VDC at up to 15 amps, for a maximum of 2100W, and AIMS's manual estimates about 2.5 to 3.5 hours for a full solar charge in ideal sun at the maximum solar wattage. The AC wall input takes 90 to 140VAC at up to 16 amps from a 15A outlet, with a Slow and Fast switch that sets the charge rate at 900W or 1800W.
With wall power connected and the AC input breaker on, the outlets run on grid power, and the station switches to its battery within 20ms if grid power is lost. AIMS notes this is not a UPS, so don't use it for equipment that needs uninterrupted power, such as data servers or workstations. In EPS mode, keep charging plus load within 1800W and run one appliance at a time.
The front panel has one 30A max AC outlet and two 20A max AC outlets with hinged covers and over current protection switches, plus USB-C and USB-A outputs. USB-A provides 5V/3A, 9V/1.8A and 12V/1.5A (18W max), and USB-C provides 5V/3A, 7V/2.4A, 9V/1.8A and 12V/1.5A.
Large 9-inch wheels and a folding handle let you roll the station into place and fold the handle for compact storage. It carries an IP54 water resistant rating, operates from 32°F to 104°F (0°C to 40°C), and includes overload, surge, short circuit and over-temperature protection plus an AC input circuit breaker.
Job sites. Run grinders, drills, core drills, contractor lights and tool chargers on a site with no power, and recharge from solar panels during the day.
Power outages. Run a refrigerator, microwave, lights and electronics from the battery, and AIMS notes it can even run air conditioning units. The EPS function covers one critical load at a time when grid power drops.
Off-grid and remote work. Pair the station with solar panels for remote operations where fuel is hard to get and generator noise is a problem.
Mobile businesses. AIMS lists food carts and pop-up retail, mobile pet grooming and detailing, and mobile tech and field offices among common uses.
Campers. Cover the core necessities of a small camper setup, including refrigeration and small kitchen appliances.
A gas generator needs a steady fuel supply and makes noise and fumes while it runs. This station works without gas, fumes or engine noise and recharges from sunlight or an outlet. Runtime depends on your loads and on how much solar you can add, so heavy all-day use calls for a solar plan.
The base unit stores 5040Wh in one rolling case. If you need more runtime between charges, the optional AIO-5KWHBAT pack adds another 5040Wh while you keep the same inverter, outlets and charging inputs.
Add up the running watts of everything you'll use at the same time and keep it under 4000W, with short peaks up to 7000W. AIMS's estimates list a refrigerator at 700-1000W, a microwave at 1000-1200W, a coffee maker at 1500W and a 15,000 BTU air conditioner at 1600W. AIMS notes that usable output is lower than the rated capacity because of efficiency losses, typically about 10%.
Before connecting panels, confirm the array's open circuit voltage is under 150V and its current is under 15A, as AIMS's manual directs, up to the 2100W maximum. AIMS notes that wiring panels in series is most common.
Yes. You can connect one optional AIO-5KWHBAT battery pack, which adds 5040Wh. AIMS says total capacity can reach up to 10,000 watt-hours.
Yes. With the AC output turned on, set the charge switch to Slow for 900W charging, which allows normal use of the AC outlets. The Fast 1800W setting is for charging with the AC output turned off. Set the switch before you plug in the AC charging cable.
AIMS advises storing it in a dry, ventilated place, avoiding long-term storage above 113°F or below 14°F, and charging and discharging it every 3 months.
The optional AIO-5KWHBAT battery pack is not included.
The AIMS Power 5.04kWh Portable Power Station brings 5040Wh of LiFePO4 storage, 4000W of pure sine output, 2100W of solar input and room for one extra battery pack. If you'd like help matching it to your tools, home loads or solar array, the Outbound Power team is happy to help.
