This is one of my most satisfactory designs, the thing is very simple, constitutes only by two parts. The lamp head selects the belt boosted circuit LED lamp holder. The power supply only consists of one 120 farads 2.3V farad electric capacitor.
Why do I like this design?
1 The structure is very simple and the gross weight only has 19 grams;
2 Permitting instant charging without possibility of any damage, the charge speed may be several dozen times than lithium battery, the nickel hydrogen battery and nickel-cadmium cell;
3 As an unusual environmental protection image, it may use solar cell board and hand generator to achieve rapid charging rate;
4 The compatibility is strong, you may use nearly each kind of ordinary battery and even the worn out battery to charge;
5 Sufficient number of charge and discharge may achieve 100,000 times compare to several hundred times in most ordinary lithium battery;
6 Permitting immediate charging(maybe a few second or a few minutes), once full charging will be allowed to read over one hour or two, providing the majority of illuminations and reading demands;
7 One thing, multipurpose use, it may act as the substitutes of power source, also may use in the outdoors ignition, a new kind of ignition method;
8 Possessing the turn switch, structures integrity;
9 functions are reliable, on condition that the ordinary battery is unable to use its key role would be allowed, so it's specially suited for the long distance travel without any backing.
turning clockwise is on, anti-clockwise rotation is off
