Recharge from 65% to full takes over 4 hours with 3 x 7.5 and 1 x 5 batteries. The power consumption of 400W is about 3 hours of operation with 3x7.5 and 1x5 batteries. Definitely nothing sustainable in an emergency. First, the idea behind it contradicts the battery documentation. The documentation states that batteries that have not been used for a long time should be discharged. But to use it during and unplanned emergencies. Then you need to keep your batteries constantly charged. As the device itself is a terrible charging station. Only one battery is slowly charged at a time. Until the charge level of that battery is equal to the next lowest battery or battery level. Then it still slowly charges the batteries with the lowest level and switches between them evenly. Turn waiting for a fully charged battery to use in other devices into an excruciatingly long wait. Finally, it is a disadvantage that the device can only charge or sockets. This limitation makes it a terrible device during an extended power outage. Why do you need a device that can turn on, for example, a refrigerator, medical equipment or electronic devices when there is no electricity? But then the power comes back when charging, your batteries will be charged quickly while your devices will continue to be powered. Some will say that you can just plug your devices back into the outlets that are working now. But this is assuming that your home. But even if your house is for that much money, why would you? This is a simple oversight that should never have crossed the drawing board. But it is, and that makes this device a terrible emergency powerhouse. But nothing more. And finally, the Wi-Fi cards in it are terrible! Now how to connect and keep it connected. Although the range of Bluetooth is acceptable.
