WIRELESS CHARGING AT A GLANCE: PITFALLS

PITFALLS

One way around the problem is buying a compatible battery and induction station pack for your device, where the manufacturers have ingeniously put the secondary coil in the battery. Other devices for the iPhone charging pads require a cable, or some sort of case that plugs into the iPhone connector.

The biggest disadvantage of inductive charging is the compatibility issue detailed above, and I guess this will only be fixed in time as more manufacturers include wireless charging coils into their products. The next problem with inductive charging is its lower efficiency and increased heat problems in comparison to direct contact charging. The further away the coils are, the weaker the charge. And this only increases the charging time even more than the already “slower than wire” charging time.

The requirements for the system to be presented are that it be incorporated into a base station and the operating frequency is set. The design of the board and choice of antenna for the stand are the focal point of the experiments that are to be performed. In order to prove the concept, power needs to be supplied to the energy harvesting circuit by an external transmitter. This transmitter will send a signal at the set frequency. Our test system will then receive this signal through the energy have sting circuit. This circuit is the fundamental design problem of this thesis. This circuit will convert the received signal into DC voltage to charge the battery. The RF transmitter, the analysis of the cellular phones to be used, and the modification of cellular phone stands to accommodate the circuitry to be designed are elements of the research covered in this section. A set of experiments will be conducted to demonstrate the feasibility of wirelessly charging a cellular phone battery.

Representative APR 391%. Average APR for this type of loans is 391%. Let's say you want to borrow $100 for two week. Lender can charge you $15 for borrowing $100 for two weeks. You will need to return $115 to the lender at the end of 2 weeks. The cost of the $100 loan is a $15 finance charge and an annual percentage rate of 391 percent. If you decide to roll over the loan for another two weeks, lender can charge you another $15. If you roll-over the loan three times, the finance charge would climb to $60 to borrow the $100.

Implications of Non-payment: Some lenders in our network may automatically roll over your existing loan for another two weeks if you don't pay back the loan on time. Fees for renewing the loan range from lender to lender. Most of the time these fees equal the fees you paid to get the initial payday loan. We ask lenders in our network to follow legal and ethical collection practices set by industry associations and government agencies. Non-payment of a payday loan might negatively effect your credit history.
