Induction Charger Basics

"I was asked generally how much more an induction charger would be than a normal, metal contact charger."

How much more what? Dollars? Pesos? Watts? Volts? Amps? BTU's? Lbs, grams??

Please provide us units for comparison.

Thanks for the response. I'm looking to find out the cost implications of induction charging. Being a night light, let's assume 2 to 4 AA rechargable batteries will be used.

The cost for who? The cost to manufacture the system? The cost for the consumer in their electric bill?

The cost to manufacture the system.

I go with the first post.

You might try Search GlobalSpec or Google.

Do you work for a company who is making a, kids portable night light?

Yes, I work for a company looking to make a kid's portable light. No comparison can be done yet because it is only an idea so far.

The question posed to me is of the highest level. "What are the cost implications of using an induction charging base vs. a metal contact base station?"

Thanks for any and all help.

The cost comparison of an inductive vs. a contact charger will depend on the volume to be produced and creative ingenuity of the designer. Unless someone responding to this forum thread has active design experience, it will be difficult to obtain an accurate estimate. The cost of replacing contacts with the induction coils in the charger and product could likely be as much or more than the charging circuit.

When my electric tooth brush changed from a contact to an inductive charger the price went up about 30% (about 10 years ago), but I don't know how much was based on cost and how much was based on the market's willingness to pay for a safer, more reliable product.

Sorry I could not provide more.

Thanks.

If anyone has specific design experience, I'd really like to hear about it.
