    USB wall charger question.

    Hey folks!

    Just got a couple Niterider Lumina 750 lights and its easier for me to charge them via a wall outlet.

    Will any wall adapter work? Like the one that came with my LG phone?

    Or is there something more specific I need?

    Don't want to harm the batteries/light.

    I have that same light, just use a phone charger.
    The output rating on most phone chargers are 1 , 1.5 and some are up to 2 amps.
    Slower charging is probably ideal but those 3 ratings will be fine. Can it take more ? Not sure.
    If you have something like a 5.0 amp output off and a/c to USB, avoid that unless you confirm specs on the light that it's safe. Fast-charging the lamp may affect battery life for recharges.

    ADDED - The manual shows 0.5 amps = 5 hours to full charge and over that ampere is "intelli charge" to full power in 2.5 hours. It may have a smart circuit for protection on bigger output. The manual it comes with is quite vague.

    I've used USB chargers for everything from old Blackberry's to my Surface to a car adapter for years, no damage to the lights yet. Mine are approaching 5 years old and going strong.

    if it outputs 5~ volts it will work fine

    what matters is amps. if it has low amps like .5, .8. 1...anything below 2.1 then it might take some time to charge. if it had 10 amps that is fine, the light will draw what it needs

    it's the output volts you need to worry about, as long as that matches
    what the light needs, you are fine

    well this is interesting.....

    I tried my phones wall charger and it wouldn't charge the light.

    Then I tried a USB cord on my computer (from a kindle) and it wouldn't charge it either.

    I had to use the specific USB cord that came with the light via my computer.

    The voltage for all USB charger outputs is the same. There are differing levels of current output, though. For lights or other high-current batteries your problem is going to be not enough power (longer charge time) rather than too much (damage). I use a Anker USB charging bricks ($13) for my Specialized Flux Experts and other such stuff for charging in the garage, I use a power strip with USB sockets in the workshop.

    NightRider has a reputation of making lights that only work with their proprietary accessories. Wonder if that's what is going on here?

    I just went ahead and ordered the Niterider brand USB adapter to be on the safe side.

    If the adapter/light would be conform with the USB specifications, it would work with every cable/adapter.
    USB charging

    Offering cheap 2 electronics for 10x the price seems greedy.

    I have two Lumina 650s (2-3 years old) and a Mi-Newt 350 (6+ years old) and I've used everything from 1 piece Blackberry chargers (no detachable cord) to iPhone plugs and any cord that's lying around the house. I've also plugged them directly into computers and my car's cigarette adapter via USB. Not once did I have an issue with charging and the batteries are still going strong.
