Car Battery Fix Yourself

Can You Use Any Charger With Any Mobile Phone, Notebook, Camera, or Tablet? 

Every mobile phone, notebook, and tablet appear to come with their own charger.  If you’re like me, you have probably compiled a number of chargers through the years.  So the question becomes: is it safe to use a charger with your phone, laptop, camera, or tablet that is not the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this guide, we will concentrate on three types of chargers: laptop chargers, micro USB chargers (these are used with telephones, tablet computers, and cameras), and Apple Lightning Connectors.  While some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are fairly specific to the device they come with.  However, there may be some generic chargers which boast the ability to be interchanged between notebooks.  This always requires changing of the charger”head” and might not be the best charging amperage or voltage to your device.

Micro USBs are designed to be interchangeable, and are standard in many smartphones, Android devices, and tablets.  Micro USB chargers typically have the exact same voltage, but may draw different amps.  I will explain this further later and how to know if the charger is safe to use (based on its listed amps and voltage).

For older devices using a 30-pin charge interface, a connector can be used to charge with the Lightning Connector.

In order for a charger for use on another device, it’s essential that the plug  of the charger (the”head”) fit securely into the charging port of the device.  Micro USBs are the same across the board as far as charging heads, while notebook chargers are often specific to both make and model.  However, the plug fitting firmly is only one part of the equation.

Somewhere on the power brick of the charger you will find a label with the charger’s voltage (V) and amperage (A).  For other types of chargers, like a smartphone charger, this information is usually found at the base of the charger, where it would meet the wall.  For the device you’re trying to control, the voltage and amperage required will be seen on the battery that came with the device or on the manufacturer’s website.

Voltage is how much power the charger will draw in the apparatus, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to approximately 5V, while a notebook can pull up to 25V.  A charger must equal the voltage needed by the device.  This is important: drawing too high a voltage could short out the device and possibly even start a fire, while too low a voltage will fail to charge the battery.

Amperage is how quickly power is”pulled” into the apparatus, or how much power is used by the device.  The amount of volts will never change, but the quantity of amps that the system pulls may change based on how hard the unit is working.  The number that you locate on the battery that came with your device will be the max amount of amps which may be pulled from the device.  The amount found on the charger is how many amps can be pulled at once. If a unit is paired with a charger which can’t support the amp requirement, it can burn out the power supply and kill the apparatus.

So for those who have a modern USB device (smart phone, tabletcomputer, or camera) you can plug into a high-amperage USB port and enjoy quicker charging (as long as the voltage is equal).  *Site Note: if you have an older device, it might not work with USB interfaces that employ the newest Battery Charging Specification.

If The Micro USB  Charger’s Voltage Is Not 5v…

Some devices might have their voltage listed using a plus/minus on it like that: 5v +- 5%.  If this is true, you may use a charger rated at 4.75 to 5.25v because that rating is telling you is that the device can take 5v minus 5 percent of 5v = 4.75 volts  OR  5v and 5% of 5v = 5.25 volts.  So this means anything between 4.75 t0 5.25v is safe to use (as long as the amperage of the charger is equivalent to or higher than the device’s listed amperage).

An interesting thing to note is all chargers supply a higher voltage than the batteries they charge.  That’s pretty much how they work.  There has to be a voltage differential to generate the necessary current flow in the proper direction to charge the battery.  If you look at your vehicle, it’s a 12V battery, but average alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The issue with knockoffs, particularly cheap knockoffs, is that they often don’t support the power needs of the apparatus, or are not built to keep a steady flow safely.  Overall, it’s better to stick with the charger made for the device you are using.

Now You Know How To Safely & Effectively Swap Chargers

I hope this article was able to assist you.  Now you know how to safely and effectively use a charger that did not include your smart phone, laptop, camera, tabletcomputer, or other apparatus.  Be certain you follow exactly what we said and you should be ready to go!
