Is your mobile device not charging properly, and you suspect the new charger that you bought recently?Do you want to check If your solar charger is giving proper current for your mobile device?Specification:? Input voltage : 3.20 - 15.0V? Resolution: 0.01V (/=10V)? Measuring current: 0.00 -3.00a (10a max, but cannot work in 10a for long time)? Resolution: 0.01A? Capacitance measurement: 0-99999 MA/H? Capacitance accumulation: Yes? Power testing: 0.00-9.99-99.9W? Over-voltage alarm: when voltage >/=5.6V, voltage digital point will Flash quickly? Lacking-voltage alarm? Over-current alarm : when current >/=3A, current digital point will Flash quickly? Short-circuit alarm: current digital point will Flash quickly dual USB output? Output I (dual function - device charging and data transfer)The charging current, in this case, is determined by compatibility. you can view the voltage and current values at the same time.? Output II (device charging only)The built-in intelligent charging control IC matches the most appropriate and safest current for your devices automatically. It is used mainly for non-original chargers, but it is suitable for original chargers as well. This universal USB gadget is suitable for most of the mobile phones, mobile power, tablet PCS and other USB devices, like BC1.2, yt/d1591-2009 and non-bc1.2 (including iPad, iPhone and Samsung Galaxy).Get yours today by clicking "add to cart" above!
7-MODE USB MONITOR ---- voltage measuring range DC 3.20~30.0v; current measuring range 0.00~3.00A (10A max.); other measuring parameter: capacitance, power going to your phone/battery pack. With 7 mode, one button to operate.
MULTIFUCNTION ---- can be used for capacitance checking, capacitance clear, over voltage and under voltage alarm, over-current, and short circuit alarm, easily test the power/quality of the chargers and USB cables.
DUAL USB OUTPUT ---- two USB output available, can be used simultaneously. Output I: be used for device charging and data transfer; output II: only for charging mobile phones, tablet PCS and etc. Output I Support QC 2.0 9V & 12V charging, but don't insert any device in Output II when using QC 2.0 Charging.
DUAL COLOR LED ---- with red and blue dual bright color LED display, easy to monitor the charge voltage and current of digital USB devices to ensure the optimal charge rate.
