The ALLPOWERS S2000 Pro Portable Power Station has a 2400W inverter matched with a 1500Wh battery. Aimed at larger deployment use cases, the Pro model specifically includes a 30A power plug for high-power-draw devices.
In terms of technical specifications, the S2000 Pro has a battery capacity of 1500Wh and an inverter rated for 2400W. It’s not terribly large, measuring 14.76 x 9.64 x 9.84 inches, and coming in at just under 32 lbs. The power station features one 30A outlet, four AC outputs (continuous: 2400W, surged: 4000W), four USB A outputs, one car output, and two USB C outputs. The AC input is 1500W 110V, and the solar input is MPPT 18-70V, 18A 650W max.
The S2000 Pro also offers pass-through charging and a UPS mode to keep devices operating during inclement weather or other unstable power conditions. Pass-through charging is an important feature with these larger power stations, as it also enables internal power supplies and, in many cases, much faster charging speeds.
The S2000 Pro also supports Bluetooth wireless connection with the ALLPOWERS App. This means you can remotely control the power station from your phone, with a stated range of around 10 meters. In terms of battery chemistry, this unit includes the older NCM or Ternary battery, as opposed to the newer LiFePO4 cells in many newer models. ALLPOWERS lists the S2000 Pro’s battery as havings a lifespan of over 2500+ cycles to 80%.

ALLPOWERS S2000 Pro Testing
In our testing, the ALLPOWERS S2000 Pro had a lot of good features on paper, but the execution of those left a bit to be desired. The onboard controls were sometimes tricky to use, making it challenging to get the unit powered on or the AC power inverter running.
From an off state, the power button with a short or long press didn’t always wake the unit. Even when the system came online, pressing the AC button with a short or long press didn’t always turn the inverter on right away. After a bit of trying, though, the button finally worked, and the power outlets were activated. On the flip side, the DC power button always worked. If the unit was off or on, clicking the button woke the unit up immediately and turned on the USB ports.
The Bluetooth connection fell into the category of a nice-to-have feature, although it also had its own set of problems. For example, during the first half of charging the unit, we could never connect to the S2000 Pro. The app could see it but never established a complete connection. It seemed that interference of the system charging itself limited the connection to some degree.
When the system finally connected to the app, we had a similar, but more limited, experience to the smaller ALLPOWERS R600 unit. The app interface is really only useful to show you the incoming and outgoing power and turn the AC/DC sides on and off. No advanced settings are available on this unit. A way to change the charge speed would have been convenient since, at its peak, the unit ramps up to around a 1400W+ charge range. Not all situations need or can leverage peak charging rates.
Another odd quirk with the app is the time remaining indicator during the charging phase has a remaining time figure of discharge rates, not how long it takes to finish charging. In our case, at about a 56 percent charge state, it had 30 days remaining.
When we measured the output capacity of the internal battery, we saw significant calibration issues with the battery. For example, when running our discharge test, the unit powered off with 22 percent remaining.
During our recharge test, the unit went from 56 percent complete to 100 percent in fewer than 10 minutes. With a claimed 1500Wh battery, we measured a discharge capacity of 920Wh with a 350W load. During the charging stage, we measured total power consumption of 1090Wh until it hit 100%. These figures also hint toward lackluster battery calibration.
Conclusion
The ALLPOWERS S2000 Pro has a large 2400W power inverter and a 1500Wh battery, although, in our testing, there were many concerns with the unit’s design. Our sample had wide charging discrepancies, with the unit turning off with 22% remaining or finishing charging at 56%. While we measured around 1000Wh of power going into or out of the unit in this range, it still needs to be more helpful for a user trying to estimate the remaining runtime of this unit in the field.
Based on our testing experience, it is difficult to recommend this model to our readers.
