Size:6.5-35V to 5V 2A Description: Voltmeter range: DC4.5V-35V.Net Weight: 13g Size：58mm*21mm*10mm（L*W*H）Output current capability 5V/2A (input voltage to a regulated output voltage of 5.0V when the 6.5V-40V)Features：Button (Output Enable button) switch USB output, a key (low-power button) to enter the ultra-low powerWith self calibration, high accuracy.With reverse connection, over-current and over-temperature protection.USB power indicator.Terminal for easy access lines. Application:B: Output current capability 5V/2A,suitable for various USB devices, stable voltage.Package include: 1pcs DC-DC Buck ConverterAfter the module is powered on, you can check the voltage in real time. If you need to charge your mobile phone, tablet, MP3, etc., please press the “output enable” button.At this time, the USB power indicator is on and the USB output is 5.0V.If you need to turn off the digital display, press the ""Low Power"" button.At this point, the module enters the low-power standby mode, and the USB output is turned off accordingly.Please Note: This module defaults to D + D-short, which is compatible with most mobile phones and has reserved a variety of phone identification resistor mounting locations.If you need to install the identification resistor, please cut off the wire connected to D + D- and add it yourself. Please pay attention to the input voltage before use."

YH11062PCB Boost converter works as advertised
I used this little PCB to make a desktop 5 volt power bank to power electronic projects. A single A123 26650 LiFePO4 cell will suffice to run an arduino for several hours. As I am using LFP cells the supply voltage is always between 2.5 and 3.6 volts. The well matched cutoff for the YH11062PCB boost converter is is 2.6. volts never see the LED as green. The main control chip is a 500 KHz Feeling Technology FP6298.The two terminal points labeled “KEY” are for a single pole double throw switch that functions as an On/Off switch for the positive side of the incoming direct current power. As implemented in DaFuRui’s product offering this function has been superseded by a zero ohm resistor on the reverse side of the printed circuit board. If a On/Off switch is desired then this resistor can be removed and a appropriate switch installed (but it is probably more practical to install a switch ahead of the PCB). The missing surface mount diode is an option for reverse current protection (a trace would need to be cut).

Works perfectly
This one actually works for my projects. I’ve bought a couple of these booster chips to build a power bank for phones and have been disappointed in the other ones. It outputs 2 Amps for faster charging and doesn’t overheat. More expensive than others I’ve found but functionally much better. I did remove the led so it wouldn’t drain battery and it continues to work great!

Only one works!
One of the converters had too much of a solder glob on one of the fuses and made it hard to work with, now only one works for my project.... Don't buy these!

Fire Hazard
Had one die as soon as a load was applied and another catch fire when I applied power, before there was even a load on it. Not willing to tempt fate by trying either of the other two.

Work great
Loved these little u its. Worked great

you CAN split them in 2
For those of you saying these are bad because its 1 pcb... please use your eyes, there is a perforation, you can split it in to 2 with a little force.

Perfect for small charging needs
Compact and well regulated - works all the way down to 5.5 volts on weak batteries. Very impressed.

Perfect for the solar panel hook up
This is perfect for a solar panel hook up positive or negative in positive and negative out to a battery then usb
