I need to charge my phone and wanted a direct charger, I'll get a battery pack charger later, but need a charging port.
So I went to Kohl's, tried 4 time and they all failed (same brand). I tried Walmart and finally O'Reilly's Auto. The O'Reilly is a USB port direct to 12VDC, so maybe that one will work and so far it seems to be working on a test battery, but so did the others.
Some of these have been 1 and 2 amp USB output and one from Walmart had the iPhone cable built in and claims 2.4 amp.
I've wired to a cig adapter, then straight to the battery, still, each one has failed.
The best I got was an on/off/on/off/on/off repeating pattern from one as it seem to be resetting itself.
So I'm kinda lost on this. I figured poor ground, too high/low input voltage, weak + connection, etc...
That's when I went straight to the battery. I got one to work for a while by holding it directly to the battery, then it ended up dying after a short time.
Does anyone know of a brand that actually works on a motorcycle and does about 2 amps. IDK if the iPhone matters, should be the same for Android.
I've tried Kohl's, AM/PM, Walmart, O'Reilly. O'Reilly had about 10 choices and I'm now trying the direct wire version, same as this:
[EDIT] maybe one like this. Anyone give this brand a try?
Also, where did you get a good "key switched" 12V+ source, no need to keep it powered all the time.
One more option, looks to be made for motorcycles:
