I'd choose to incorporate my vote for the Anker multi-chargers. Now we have 3 of such in Continue the house: just one while in the dwelling-space, just one inside the learn Bed room and 1 in my office.

I concur that noisy, spiky output can cause instability and undesirable conduct in sensitive electronics, including the aforementioned contact-screens, when charging... but a battery isn't as picky!

Those onboard regulators can cope with a certain number of sound and possess a decent input voltage selection. Laptops are a good example to work with as their electrical power materials tend to be noisier than desktop power provides given that they too have an onboard regulator.
