Who makes portable power units?Japanese and Korean companies are the most involved in portable power units for electronic devices, and have recently launched a series of products that are mainly based on direct methanol-fuelled PEFC; large-scale commercialization of these devices is planned in the coming years.
What voltage is compatible with USB Power Delivery (PD)?The input voltage range is compatible with USB power delivery (PD), accepting anywhere from 3.5 V up to 24 V. This wide range of operating voltages adds flexibility, making this solution attractive for robot vacuum cleaners, drones and portable computers.
Can a supercapacitor be used as a rechargeable power source?For moderate energy demands in portable electronics, supercapacitors are suitable as rechargeable stand-alone power sources. In conjunction with rechargeable batteries in uninterruptible power supplies, supercapacitors can handle short interruptions and can extend battery life.
What are the advantages of PEFC-based power systems?For military applications, another advantage of PEFC-based power systems is that they could be easily masked against thermal sensors, while other generation systems operate at higher temperatures and emit much waste heat. Here, cost is not a problem; fuel storage and supply logistics are the main limiting factors.
How many watts can a portable FC power?To power this range of products, portable FCs are being developed in a wide range of outputs, ranging from less than 5 W up to 500 kW. This range has necessitated further sub-classification; ‘FC Today’, for example, classify units with power up to 5 W as ‘micro FC’, and units up to few hundred watts as ‘mini FC’.
What is a portable charge system (FC)?Two broad definitions of portable FCs exist in the literature. The first definition includes FCs that are built into – or charge – products that are designed to be moved, excluding vehicl
