Result and general impression …
The Power Queen P300W Powerstation is small but mighty!
In this price segment, we would have expected the small Powerstation or large Powerbank to have one or two weaknesses, but after extensive tests and measurements we were proved wrong. Overall, the 300 Wh power station offers a solid performance and is only limited by its possible output. This is because the 300-400 watt output power is of course not suitable for operating a normal washing machine, radiator or hairdryer. However, the cooling is significantly quieter than, for example, the recently tested EcoFlow River 2 Pro. However, devices below this power are reliably supplied with power – whether on the campsite or on the road in a motorhome or even at home in your own four walls.
It would also be desirable to have a real switch that allows the battery cells to be completely disconnected from the system and that really switches off the device completely even when the AC or DC power supply is connected.
To give you a better overview, we have created a small Power Queen P300W Powerstation pros & cons list:
+ 300Wh capacity in a compact size
+ Advanced battery with LFP (LiFePO4 lithium iron phosphate)
+ Silent charging process
+ Low standby consumption
+ Mobile use with 3.6kg
+ AC with 220V 50 Hz sine wave
+ Good efficiency
+ Versatile connection options with USB-A, USB-C, DC5521, car, MC4, Schuko socket, etc.
+ Clear, illuminated display
+ Emergency lighting with SOS function
+ Stand-alone solution for camping or at home possible with optional solar panel
– Long charging time of approx. 7 hours
– No connection via Bluetooth or WLAN
– No mechanical off switch
– Cannot be used with devices over 300-400 watts
Overall, the Power Queen P300W power station is therefore recommended if you need a small power station/power bank as an occasional emergency power supply for devices under 300-400 watts.
