color display with USB port

Recommended Posts

I bought a Sondors upgrade color LCD display (with the 25 amp controller) some time ago when they were first offered at a discounted price.

I noticed it has a USB port on the right side.

I bought the Securitylng USB powered LED light off Amazon

So I could plug it in the USB port and not have to worry about recharging a light every few days; this way as long as the battery had power the light would have power. But I find the Securitylng light doesn't work with the Sondors LCD display USB port. I only get a little flash of light from it, and it doesn't work. When I try it in my computer's USB port, it works great. I am thinking the Sondors color display USB output port doesn't have enough power to make the light work.

Any thoughts? Am I correct? Has anyone tried it? Is the USB port only good for charging cell phones?

Seems like a great solution if it would work, but as it is I am sending it back.

Your first step is to measure the output of the USB port with your multimeter, which is a mandatory device for every ebike owner, from the LCD when it’s powered on.  You might also activate the light function with the control button sequence for your LCD. On both mine, it’s holding the up arrow for a few seconds. That turns on the backlight for the LCD and sends current to the extra red Higo connector cable, for some Controllers and it turns that function on for comparable lights; both headlights and tail lights. It’s probably a long shot that it controls the USB port out put but it’s worth a try. The output voltage should read 5V which is common among usb outputs.  If it’s not contact Sondors.com and ask directions to file for a support request on the Sondors Owners Facebook Page. 
BTW, I use the 3 led version of that light on both my previously labeled Sondors and power one with the KT LCD 3 Display, equipped with the USB port. Works Perfectly. As not to mislead anyone else reading these posts, these lights have No Internal Batteries.

Reddy, thanks for the info. I didn't have a meter, so I ended up emailing Sondors tech support. They told me that the LCD only has a 1 amp USB port and will do nothing but charge a phone. So my idea of using a USB powered light will not work, at least with Sondors' LCD screen. Too bad.

 On my Sondors Original, with my non USB ported KT_LCD3,  I use a Power Bank to power that Headlight. It uses 4, 18650GA  Li Ion batteries and I recharge it with a spare Apple IPad charger because it is more powerful and recharges faster than the average cell phone charger. I’ve never run out of power using the 3 LED light like your 2 LED version and it’s never discharged below 50% capacity.  I keep the Power Bank in a top tube trunk, with a few other necessities, pocket change and multi tool.  https://tinyurl.com/Reddy-s-Powerbank    
You could use the LCD USB port to recharge a powerbank.

That is an idea to keep in mind. I guess it becomes a choice of whether to recharge a regular light, or use a system like yours.  I will have to put some thought and experimentation into it. thanks again.
