Review on Eversame Multimeter Chargers Capacity Banks Black by Stephen Johnson

I would say this is the best USB tester I have seen. It has a huge amount of detail and packs a lot of information into each screen. The button surprisingly allows for a lot of customization by pressing it a different number of times. This device also has the ability to turn off the connected load when it stops consuming power, or after a set time (set by a sequence of 5 presses on the screens showing the setting of this option). Holding the button down while connected to power also gives you access to the calibration screen, but I don't feel safe changing anything there. It's possible to adjust the current and voltage cutoff points and offsets for the readings, but again I haven't changed them from the default. This tester can toggle (and back) to the Chinese display by pressing the button 6 times in quick succession. A quiet beeper is also installed inside, but not visible. A short signal tone sounds when the value is reset. Full keycodes and instructions can be found by searching the manual for the J7-T USB Tester. (There is a forum post that is particularly helpful) The circuit board is well designed and durable, and this model uses a small dot matrix LCD (for those interested).
