Questions about Xtorm Xtreme Series

To fully charge a 20000 mAh power bank with a 28 W solar panel, we need to calculate the charging time. The power bank needs about 20000 mAh / 5 V = 4000 mWh of energy. The solar panel supplies 28 W. With full sunlight, charging takes around 4000 mWh / 28 W = 142.86 minutes or around 2.38 hours. This assumes that the sun shines constantly and there are no losses. In practice, the charging time can be longer, as solar radiation can vary.

The Xtorm XP300U allows a maximum of 72 W (at max. 26 V) via the 6.5mm input. This means that the Powerstation is probably throttled. Unfortunately, most power stations can only be charged relatively slowly via the Solapanels (and 12V connection). This has to do with the fact that the strong currents needed at low voltages to achieve high performance require thick cables and generate a lot of heat. As far as I could see, the Xtorm XP300U unfortunately only has inputs for low voltages (max. 26 V). This means that the power station can only be charged relatively slowly in general, even via the supplied power supply unit. I have two power stations from EcoFlow. They also have a 230 V input and you can therefore charge them very quickly via the socket (or an inverter). However, as soon as you want to charge them directly with solar energy - i.e. not via an inverter - they also charge relatively slowly. According to the manufacturer, the Xtorm XP500 can be charged with both panels and a maximum power of 200 W.

it depends on the degree of sunshine, to have tested in field conditions, I can say that we approach more than 40W
