Cell phone users know that there is nothing more frustrating than a low battery alert in the middle of a busy day. Most people need their cell phones to be functional at all times, as they are integral to communication with friends, family members, and colleagues, whether it is via talk or text. Owners of smartphones often become dependent on them for much more than communication, using them to browse the Web, check email, download media, edit documents, add information to their personal calendars, and much more.
With the current reliance on cell phones, users consider it more important than ever to have reliable battery life. To ensure full power for their cell phone during the day, most users charge it up at night using a cell phone charger. This guide will explore some common sources of loss or damage for cell phone chargers, explain how cell phone chargers work, and describe some of the benefits of one type of charger in particular: the usb car charger in Singapore. With this information, buyers will know what to look for when they shop for USB cell phone chargers.
Sources of loss or damage for cell phone chargers
In spite of all that manufacturers do to make cell phone chargers reliable, they may eventually malfunction or fail. Users should double-check their phone halfway through the charging process to ensure that the charge is holding. If it appears that the charger is no longer performing its function, users should immediately begin the search for a new one.
Another potential reason for needing a new charger is loss or damage. Chargers are relatively small items that are easily misplaced in a home or office. In a home with children or pets, cell phone chargers may be carried off and hidden by a small child and not discovered until months later, or the household’s dog may decide that the charger would make a good chew toy and damage the wiring. Buyers who find they frequently replacing broken or lost chargers may want to stock up on several used USB chargers, which can usually be purchased at low prices from some retailers.
How USB cell phone chargers work
Learning about the interaction of a charger and a cell phone battery can help buyers identify problems and understand what type of charger they need. First, buyers should know that today’s cell phones commonly use lithium-ion batteries, which contain an anode, a cathode, and a conductive electrolytic substance between the two. The anode is made of carbon, while the cathode is made of lithium metal oxide.
When the cell phone is functioning normally, lithium ions flow gradually from the anode to the cathode. This chemical process depletes the battery energy resources over time. The number of hours of cell phone battery life depends on the level and on the type of activity. For instance, on a typical smartphone, a simple phone conversation takes much less battery power than video streaming or gaming.
Eventually, the battery’s charge drops low enough to trigger the low battery alerts with which most cell phone users are familiar. If users ignore these alerts and continue to use the cell phone, the battery will completely run out of power and the phone will shut down.
If possible, users should charge the battery as soon as they receive an alert. Otherwise, their phone may power down at the worst possible moment. In the case of a USB charger, users would simply connect the charger to the appropriate port in their phone and plug the other end into a USB port on a personal computer or laptop. The device serving as the power source needs to be on while charging takes place.
As the current flows from the power source through the charger’s wire and into the cell phone’s battery, it initiates a chemical reaction, causing the lithium ions to flow from the cathode back to the anode. The reaction allows the battery to store the chemical energy and use it later to operate the cell phone. To find out more about our mobile gadgets in Singapore click here.
