The DIY Modular Open Source Laptop is designed to be charged by any combination of solar panel, handcrank generator, USB AC adapter, USB car charger, USB port or thermoelectric generator. Unlike most rechargeable electronics, each charger can charge the USB powerbank battery of the DIY laptop seperately from the DIY laptop. This flexible and modular charging ensures the DIY laptop never runs out of energy, yet never needs to be charged either.
USB solar charger: SOKOO 22W 5V 2-Port USB Portable Foldable Solar Charger ($55)
Handcrank generator: K-TOR Pocket Socket Hand Crank Generator Portable Power Supply 10 Watts 120 Volts ($60)
Pedal generator: K-tor Power Box 20 Watt Pedal Generator ($200)
Thermoelectric generator: Camping Stove Thermoelectric Generator TEG Power - Devil Watt 15 Watt ($304)
Each reference charger can provide the 5V 2A needed to charge a USB powerbank at full speed. The most convenient charger will depend on the situation.
Solar panels can provide >150 W unattended outdoors at daytime.
Handcrank or pedal generators can provide <150 W attended indoors or outdoors, day or night. Handcrank generators can be used while standing or moving, but pedal generators can be used while also using the DIY laptop.
Thermoelectric generators can provide >150 W unattended outdoors, day or night. Indoors with ventilation.
USB AC adapters can be used wherever there is AC electric grid.
USB car adapters can be used with most DC electricity sources such as 12 V car batteries or six 1.5 V AA batteries in series. USB car adapters can also convert DC from solar panels, thermoelectric generators, handcrank generators, DC wind or hydroelectric turbines into 5V DC for charging the DIY laptop.
