Description of Use: Double Template Size:about 3.5x3.50cm/1.38x1.38in Double template: 3V-14V battery can be converted into AC220V and AC110V and DC220V Output voltages: AC220V AC100V DC220V power output rate 0.1W-26W If the input voltages is 8V, the output is 1W-10W (automatically change the power, according to the load and righteousness) If the input voltages is 10V, the output is 1W-20W (the power changes automatically according to the load). If the input voltages is 11V, the output is 1W-25W (automatically varying power according to the load). If the input voltages is 12V, the output is 1W-35W (automatically varying power according to the load). If the input voltages is 13V, the output is 1W-40W (automatically varying power according to the load). Package Includes: 1PC DC12V to AC220V Conversion Power Adapter note: Due to problems of lighting effect there will be certain tolerances in product, please understand. Please allow 0-1cm error due to manual measurement
