Product Information

Legacy proprietary fast-charging protocols are numerous and considered a ripe pain-in-the-butt to understand why certain combinations of chargers, cables and devices just work and others are slow. It can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks; measure the charging power of mobile phones and the input and output of mobile power supplies; test the fast charging protocol of chargers.

Ripple Measurement: Easily detect and measure ripple, a crucial factor in assessing the quality of power supplies.

Tests were performed with the FNB58 attached to a Digilent ADP3450 Analog Discovery Pro as a Linux-based device with LAN and USB connectivity. Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable).

The settings section allows for configuration of brightnesses, standby times, refresh rates, temperature units, language, whether the screen rotates on accelerometer sensing, various recording options, resetting to factory defaults and information about the device and firmware.

groups of energy records, battery capacity calculation in one step, support 10 groups of charge and discharge energy data records; built-in battery capacity calculation formula, through the recorded data can quickly calculate the battery capacity.

But keeping in mind that this is a USB gadget, meant for use for quick diagnosis or to get out of a specific slow-charging situation, it really seems to do things more than just well-enough.While the manual is a bit difficult to understand and the menus on the device can be a bit quirky at times, it does a lot of things for its size and most things just seem to work. Torx screws are at all four corners of the rear, with a plastic window on the rear, likely acting as a radome for the Bluetooth radio in the unit. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. FNB58 USB tester is a high-reliability, high-safety USB voltage andcurrent detection meter and a mobile communication terminal fast chargingtrigger.
