USB/Micro USB

Bought me an digital endoscope for some silly reason and have a battery question.

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1


It comes with a 2600mAh Lithium battery. For charging is has a USB/micro USB cable.

Instructions say, "Only use 5V indoor home use USB charger to charge device" Problem is I don't have a USB charger.

I do have a charger for my Trac phone with a micro USB end that says:

PRI 100-240V~ 50/60 HZ 160mA
SEC: 5.0V=550mA


I would think as long as the output is 5.0V and the correct end it should work?

Thanks

I think you will be fine with that charger.

Worked fine, charged the battery in ~ 3 hours and no flames.

USB jacks on PCs and laptops also have enough current to charge that battery.

I Had No Idea

Can I blow up my USB device?

In short, no: You can plug any USB device into any USB cable and into any USB port, and nothing will blow up and in fact, using a more powerful charger should speed up battery charging.

How USB charging works, or how to avoid blowing up your smartphone | ExtremeTech


When I plugged it in the power button started flashing red (from my younger days flashing red lights made me nervous) then after a few hours it shut off and battery read fully charged. As usual, nothing in the instructions about that.

Apparently it won't over-charge which is what I was worried about.

Thanks

Not all equal

I noticed that often while driving with my phone in its car mount, plugged in and streaming music and sometimes navigation running that I'd arrive with LESS power than when I started. This led to a long examination of power adapters and cables. I now have high-current charging hubs and 12V adapters and thicker high-current USB cables of various lengths at home and in the car. All my devices charge significantly faster than they did with the department store or even OEM accessories.
