Review: Useful Battery for Power Outages - --- Pros --- Compact size for the amount of power. Fast charging. Solid build. Easy to use app. --- Cons --- Slight humming noise during charging, especially on 1200W+. --- Thoughts --- Quite a powerful battery. Used it to charge two laptops, e-bike, e-scooter, and battery pack all at the same time. Battery was shipped with 50%, used 18% in 4 hours (at the output rate of 20W to max of 311W) the above mentioned devices. Charging the battery back to 50% from 32% took less than 2 hours on 1800W charging through standard outlet. The buttons to enable/disable different outlets was more useful than thought. It also saves power by not having to keep all the converters inside enabled and running. The battery is heavy, but the build is sturdy and feels high quality. The wheels work fine on bumpy sidewalks. The display is useful in checking battery level, output power, and charging rate. The app (MyGro APP) is pretty easy to use. The dashboard page packs a lot of info about the current status of the battery, and just like with the actual battery, allows users to pick what type of outlets are enabled. Having the manual inside the app is also very useful, it saves time having to look up online for the model and make of the current battery. Only complaints for the app is text do not have enough contrast and some English translations being a bit too long for the space provided. Would like to see a revision with the handle moved to the opposite side of the wheels; that way people can pick it up with the handle even if it's turned over when lugging it. Also would like to see some changes to the Wifi/Bluetooth button; it is too easy to accidentally hit the button and turn off the connection. Perhaps making it a "hold to toggle" like with the power button would help? In that case, the enable/disable outlet buttons could also benefit from this feature. Overall, this is a well-built battery that can be used during power emergencies and outdoor use without hassle, along with its companion app that makes it easy to manage and monitor.
Review: Very good and heavy duty power station - Very impressive and high quality portable power station Works great in our cabin. Run air-conditioning, fridge and other appliances directly from the power station without any issues I charge with solar panels and also anderson cable plugged into the vehicle while running It's pretty heavy and a little difficult to turn but the long handle is very convenient to move to around Did have some issues with app not updating the firmware. I contacted the after sales team and they help resolve the issue very quickly The device supports 12 to 60v solar PV with h max 2000W 800watt anderson input
