Wireless charging newbie here. Want to try it out on the cheap. Amazon seems to offer them as low as 6 dollars, but willing to pay a bit more than that. What are some good inexpensive ones you folks like that will work with an Insignia soft shell case still on? (I saw a charging stand that offered an additonal outlet for headphones and such, an attractive bonus, but it had no reviews or question and answers about the product.) Anything I need to know before I enter this brave new world? Any pleasant or unpleasant surprises awaiting me? My primary use for it would be on my bedstand at night while I sleep.
