In extreme situations far from settlements, a reliable renewable power source is of particular importance. As practice shows, the best option is compact solar panels, which are able to provide the operation of small electronic devices.
The Israeli company Kalisaya has offered its own version of portable solar panels that fit in a small portfolio - KaliPAK. It is available in three versions - KaliPAK 201, 401 and 601. Thus, the 201 model combines solar 20-watt panels with a 192 watt-hour battery, and the more powerful 601 model weighing almost 7 kg has 40 W solar panels and a 562 watt-hour battery.
The solar panels are folded in the case. To bring them into working condition, they must be deployed and installed on stands. The case has several ports for connecting devices, a Bluetooth system for controlling the device from a smartphone and a control panel.
In addition to the basic kit, there is an option with an LED backlight, an inverter for starting an AC device, a car adapter for a cigarette lighter, a waterproof lamp with a 7800 mAh battery and a splitter for simultaneously charging multiple devices from a single port.
