Please carefully confirm if you have the same battery as described below, otherwise do not place an order!
If the product cannot function properly due to battery mismatch after placing the order, the buyer is responsible for it themselves!
DC Input: 21V The DC port cannot charge the battery! When your battery runs out of power or you don't have a corresponding lithium battery, you can choose an adapter with an output of 21V to provide power to the lamp! You cannot directly charge the battery with an adapter!!!!
