The Spark is a wireless charging receiver that allows any phone or tablet to use ChargeSpot. Simply place the plugged in Spark over a ChargeSpot to begin charging.
Many new smartphones do not require the Spark. They have a wireless charging receiver already built in (For example, the Samsung Galaxy S7 and S7 Edge).
