Colour TFT Dual USB Power Monitor YZXstudio ZY1270 QC 3.0 Auto Fast Charge Capacity Tester

This is the latest addition to the extremely popular YZXstudio series of USB Power Monitors. This model features a large 1.3" 128x104 pixel colour TFT display for exceptional readability. It combines all the functions the ZY1266 LCD and ZY1230 OLED versions have to offer, namely 18-bit voltage resolution (up to 4 decimal places), up to 24V voltage range, Micro-USB input port, as well as a dual USB 2.0 output ports, one of which allows fast charging for Apple and Samsung devices without needing the original chargers. The Micro-USB input port allows you to connect the power monitor using a common Type-A USB to Micro-USB cable to your power source, making it more convenient to use in some situations. It is also capable of giving you a direct reading of your input cable's internal resistance (requires a constant current DC load).

This device is also Qualcomm QuickCharge (QC) 3.0 compatible. Please see the comparison chart in one of the attached images to find out the differences between all the different versions of these YZXstudio USB Power Monitors.

Just like the other versions, this device allows remote data logging by connecting a UART USB/Serial adapter, or a Bluetooth module. Like the ZY1265 and ZY1266, this model also has PCB footprints for the necessary components (a Bluetooth module, a P-Channel MOSFET, and a 3-pin spring loaded connector). Please choose whether you want the device to come with these Bluetooth enabling components or not when you make the purchase. If you choose to get one without these Bluetooth enabling components, you can still add them yourself in the future. Users will need to use their own serial communication software for the actual logging and data analysis though. The USB Power Monitor simply sends the raw data.

The Dave B.Reviews YoutTube channel has done a review on the similar LCD Red version (original model ZY1262), comparing it to an a out-of-cal OLED version with an older firmware which the reviewer purchased from another eBay seller: http://youtu.be/jLB8ETx_qwc.

Steve of the SDG Electronics channel has another detailed review of the LCD Red version with a mini-teardown: http://youtu.be/vpRN6XXX7WQ .

Previously Martin Lorton of the popular MJLorton channel done a very positive review on an earlier OLED version of this device, watch it here: http://youtu.be/kYQz88ZclRA

Julian Ilett also uploaded a first look video of the OLED Yellow and Red versions to his popular YouTube channel: http://youtu.be/IVNA4gvQzKo. Julian has since posted a few more videos on these USB Power Monitor devices include this one (https://youtu.be/jYfzGoLxR4M), where he also demonstrated the Bluetooth remote logging capability.
