Product Specification:Xy-101 Multi-functional hand generator emergency Portable power supply is a pure green hand generator.This product does not need to charge, hand can generate electricity, hand power generation real-time display voltage and current is a real meaning of the hand generator.The maximum power of the product can be up to 20 watts, and the output interface is rich,USB5V, DC12V(varies with the speed of hand),AC220V, among which, the maximum output current of 5V can be 3A, 12V20A, and AC220V is 30W.The hand-operated generator has no internal battery and stores power through a supercapacitor.The power stored is not too much, the internal capacitor can be filled by hand shaking for 10-20 seconds, and the built-in light can be lit continuously for more than 15 minutes.For emergency charging of mobile phones, it is necessary to continuously generate electricity by hand at a speed of no less than 60 RPM.The charging effect can be known by checking the current current value.It shows that the larger the current value is, the better the power generation effect is and the faster the mobile phone can be charged.Power: 20Wpower generation voltage : 21V (highest)USB 5V maximum output current: AAC220V output power: 30WDC jack output voltage: 5 ~ 21 VDC jack output power: 200 whand full of internal ultracapacitors time: 5~15 secondscondition cabin lights light up to 15 minutesAC220V use scope: Smobile phone charge, part within 30 w LED lights, wireless router, lamps, the LED energy-saving,unbright, incandescent lamp, other low-power electrical appliances (inductors can not be used)Capacity: 20F8 string (equivalent to 800mah battery)Product size : 220*140*80mmThe package includes1 pc of generator
