What are the types of power strips?

The types of power strips can be classified according to different standards such as functions, uses, and safety features. The common classifications are as follows: 1. Classified by function  • Basic power strips: Only provide multiple national standard sockets with no additional functions, suitable for simply expanding the number of sockets (such as powering devices like TVs and table lamps). • Power strips with USB interfaces: In addition to national standard sockets, they integrate USB-A or Type-C interfaces, which can directly charge low-power devices such as mobile phones, tablets, and headphones without an additional charger, suitable for scenarios like desktops and bedside tables. • Power strips with switches: Equipped with a master control switch or sub-control switches (each socket is independently controlled), facilitating power-off, avoiding frequent plugging and unplugging of devices, and saving electricity. • Lightning protection and surge protection power strips: Built-in lightning protection modules that can absorb instantaneous high voltages generated by lightning or grid fluctuations, protecting precision electrical appliances such as computers and TVs, suitable for thunderstorm-prone areas or connecting valuable equipment. • Smart power strips: Support WiFi/Bluetooth connection, can remotely control switches and set timed power-off through mobile phone APPs, and some can also monitor power, suitable for smart home scenarios (such as remotely controlling humidifiers and water heaters).  2. Classified by use  • Ordinary household power strips: Lightweight in design, with a cable length mostly 1-5 meters, meeting the power supply expansion needs of daily household appliances (refrigerators, washing machines, small household appliances, etc.), focusing on safety and cost performance. • Industrial power strips: Made of more durable materials (such as high-temperature resistant and shatterproof shells), with thick cable diameters and large current-carrying capacities (supporting 16A and above current), suitable for high-power equipment in factories, construction sites, etc. (such as electric welders and cutting machines). • Portable travel power strips: Small in size with retractable cables, some integrate multi-national standard plugs (national standard, American standard, European standard, etc.), facilitating adaptation to different sockets when going abroad, suitable for powering devices such as cameras and power banks. • Desktop-specific power strips: With a simple and beautiful design (such as flat cables and hidden sockets), they do not take up space, are equipped with USB interfaces, and are suitable for connecting computers, printers, table lamps, etc. on office desktops.  3. Classified by safety features  • Overload protection power strips: Built-in overload protection devices that automatically power off when the total current exceeds the rated value, avoiding overheating of the line and causing fires, which is a basic safety configuration for household power strips. • Electric shock prevention power strips: Socket holes are equipped with child safety doors (no conduction when a single hole is inserted), preventing accidental contact by young children, suitable for families with children. • Waterproof and moisture-proof power strips: With strong shell sealing (such as IP44 and above protection level), suitable for humid environments such as bathrooms, kitchens, and balconies, and need to be used with waterproof plugs.  When choosing, a suitable type can be selected according to the usage scenario (such as household, industrial, outdoor), equipment requirements (such as whether USB fast charging or lightning protection is needed), and safety requirements (such as electric shock prevention and waterproofing).
