Pros and Cons of leaving a multi-port USB wall charger plugged in?
September 5, 2013 6:43 AM Subscribe
We use a multi-port USB wall charger to charge our various devices. I'm looking for information evaluating the pros and cons of leaving said charger plugged in with associated USB cables, versus unplugging the unit from the wall when not in use.
Specifically I'm looking for info on the following:
- any known power drain of leaving it plugged in but not charging any devices (significant? insignificant?)
- risks (or conversely no risk) of fire from leaving them plugged in when not charging devices
We're trying to find the safest and most convenient configuration, and we're looking for some objective knowledge - please, no unsupported opinions "well, it should be fine" or "I wouldn't do it." We're really looking for known facts to help us make the decision.
