Features: Achieve powerful DC3.7V voltages conversion with this boosting module, transforming 3.7V input up to 1800V output for high voltages applications. Featuring voltages doubler rectification and a low current design, it delivers approximately 1500V at 3V, 1800V at 3.7V, and 2000V at 4.2V input with a continuous operating capability. Ideal for electronics enthusiasts, science educators, and hobbyists requiring reliabled high voltages power sources for experiments and projects. Perfect for science education demonstrations, powering electronic instruments, and enabling various small scale high voltages projects. For enhanced instantaneous discharge current, this module supports parallel connection with high voltages capacitors like the CBB65 series. Specifications: Input voltages: 3-4.2V Input current: about 2A Without load current: 130MA (under 4.2V voltages) Output voltages: 2000V (When the battery voltages is low, the output voltages will also become low) Discharge distance: 1.5mm Can work continuously Size about 41x26mm Package Includes: (1 piece) voltages converter module DC3.7V to 1800V note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution
