Review on 🔌 BESTEK 300W Pure Sine Wave Inverter: DC 12V to AC 110V Car Power Converter with Dual USB Ports, 2 AC Outlets, ETL Listed by Matthew Kocur

This is not an overview. know approximate numbers. Amplifier Used - Boss Acoustic Singer Pro 100W - Power Requirement 110VAC 50W Bestek 300W Pure Sine Wave Inverter Battery - Raion RG12220FP - 12VDC 22Ah (20Ah 10.5V SLA-AGM) Current Tester - Extech 380947 Clamp Meter Battery on Inverter connected, inverter enabled - 0.7A in standby mode (fan running and USB power ports active) Additional note - when inverter off but connected to battery and mobile phone connected, 0.4A current sink plugged in and on - current draw 2, 7A (2.8A connected to mobile phone) Playback at 50% volume, 2.7A continuous - 3.0A with hard attack. Based on this formula: 1A at 12VDC equals 10W AC. In this case, the amp draws 50 watts, which requires 5 amps from the battery. So based on those numbers I should get around 23 hours of use (don't forget the efficiency calculations). microphone, but I suspect that with a possible maximum peak of 4 amps, the consumption will not be much more than 3A. Added - ATTENTION - the inverter stores energy. Even after switching off and disconnecting from the battery, there is still a potential risk of sparks if you touch the wires (+) and (-) of the inverter. I have not checked how long the energy is stored or whether a blowdown resistor is installed. So if you are a musician or artist using a sound system, this inverter will power the amp at 100W for hours (based on the AH test used).
