Portable

Portable notebooks are designed specifically for today's mobility needs. All notebooks in this category have two main features: Firstly, they are designed for lightweight construction (≤ 1.5kg) and have a maximum screen diagonal of 13.3 inches so that they practically fit in a pocket. Another advantage of these devices is their low power consumption, so that one battery charge is sufficient for up to a whole day, depending on the device load. Of course, these large battery ranges can only be achieved in coordination with particularly energy-efficient notebook components. As a rule, these devices are therefore equipped with "low-voltage" processors and main memory. Storage solutions are usually based on an SSD, which is lighter than a standard HDD and has no moving parts. This means that an SSD requires less power, is less susceptible to transport damage (vibration protection) and runs completely silently. However, the biggest advantage is the very short access time to stored data. With an SSD, your notebook starts up in seconds, increasing flexibility on the go.

Battery-operated

A rechargeable battery or storage battery is a group of one or more electrochemical cells. They are known as secondary cells because their electrochemical reactions are electrically reversible. Rechargeable batteries come in many different shapes and sizes, ranging anything from a button cell to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of chemicals are commonly used, including: lead-acid, nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer).

Rechargeable batteries have lower total cost of use and environmental impact than disposable batteries. Some rechargeable battery types are available in the same sizes as disposable types. Rechargeable batteries have higher initial cost, but can be recharged very cheaply and used many times.
