What is a Portable Charger? -Compact sized plug-and-use charging dock that can be used on the go for mobile devices, removing the need for static charging through a wall plug. -Current chargers in the market are able to provide charging capacity of up to 2-3 full charge for mobile phones, reducing the need for frequent charging of the power bank. Notable brands in the market? -MiPow (HK) -Romoss -Chinese manufacturers? What is the demand for it in the market? Based on Y13, what is the actual sets manufactured etc.
-Rise of mobile devices means the need for bigger battery capacity. -For heavy mobile device users, portable charger could become an alternative power management device. -Lessen the burden of carrying multiple devices and usage of additional wires and chargers What does our inductor provide for P. Charger? Inductor is mainly found in the output design for Portable Charger, however we are trying to promote our inductor to be used in the input IC charger as well. With the usage of the inductor in input, charging time of the battery can be improved.
Our inductor is also able to sustain the magnetic field from the current flowing through providing extra energy capacity and stability in current discharge. Usage for inductor in P. Charger -Based on teardown for Romoss powerbank design, there are 2 area that our inductors can be used. 1)Output, step up regulator (Low DCR-type inductor) 2)Input, IC charger (Typical inductor) *Not required for all design* Current competitors doing promotion for powerbanks -Vishay
