The UM24 is a sophisticated USB power analyser and data logger. Featuring a large LCD display that provides unparallel data on any Type-A USB socket. User can measure voltage, current (when charging a device), Capacity, Power (Watts and Watt Hours) as well as plot graphs and much more!

Use this to analyse the power level of your USB charger, car cigarette lighter or even measure actual capacity of your power bank. Many power banks sold on international and local auction style sites list outrageous capacities that defy the laws of physics. Now you can measure the total tank capacity in a very precise way and produce an actual number.

This meter will also detect Quick Charge 2.0 and Quick Charge 3.0 as well as measure the impedance of USB cables.

Essential in checking the quality of USB cables, car chargers and general USB chargers before using them with your expensive portable devices. Many economical cigarette lighter USB chargers and AC USB chargers don’t provide clean power and may damage your device and or reduce your battery life with frequent use.

Data from the unit can be viewed on a PC for further analysis.
