Technology
A USB power meter sits between a charger and a device and shows the voltage, current, and actual power being delivered. It turns an invisible charging problem into something you can measure.
It is especially useful when two chargers or cables look interchangeable but behave differently. Instead of guessing which part of the chain is limiting the charge rate, you can see what is actually happening.
Technology
A basic Ethernet cable tester checks whether the conductors in a network cable reach the corresponding pins at the other end. That makes it useful after crimping a connector or when a cable seems dead and you want to find an open, short, reversal, or obvious wiring mistake.
A simple continuity-style tester does not prove that a cable can sustain a particular network speed under load. It answers the more basic question first: is the cable wired correctly from end to end?
Technology
A multiport USB-C charger can replace several separate power bricks when you regularly charge a phone, tablet, laptop, or accessories in the same place. The convenience is real, but the wattage printed on the charger is normally the total power available, not necessarily what every port can provide simultaneously.
The useful specification is therefore the power-sharing behavior: how much each port can deliver when one device is connected and how that changes when several devices are charging at once.
Travel
A compact travel power strip is useful when a hotel room gives you one conveniently located outlet and several low-power devices need charging. Instead of scattering chargers around the room, one cord can bring the connection to a bedside table or desk and provide several usable sockets or USB ports.
For travel, size and cord length often matter more than maximum outlet count. Also remember that a power strip does not convert voltage; anything plugged into it still has to be compatible with the local electrical supply.
