How To Repair Hoverboard Battery

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

Every cell phone, notebook, and tablet seem to come with their own charger.  If you are like me, you have probably compiled quite a few chargers over the years.  So the question becomes: is it safe to use a charger with your phone, notebook, camera, or tablet that isn’t the original manufacturer’s charger which came with the device?

Kinds of Chargers

In this article, we’ll focus on three types of chargers: notebook chargers, micro USB chargers (these are used with phones, tablet computers, and cameras), and Apple Lightning Connectors.  Although some devices have chargers using a slightly different head or charging cable, these are the most frequent.

Laptop chargers are rather unique to the device they include.  However, there may be some generic chargers that boast the ability to be interchanged between laptops.  This always requires changing of the charger”head” and may not be the optimal charging amperage or voltage for your device.

Micro USBs are designed to be interchangeable, and are standard in most smartphones, Android apparatus, 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 whether the charger is safe to use (based on its listed amps and voltage).

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

For a charger for use on another device, it’s important that the plug  of the charger (the”head”) fit snugly to the charging port of the unit.  Micro USBs are the same across the board as far as charging heads, whilst laptop chargers are usually specific to both make and model.  However, the plug fitting securely is just 1 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 notebook chargers, this charging brick is often halfway down the charger and appears exactly like it sounds — a brick. 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 attempting to control, the voltage and amperage required will be found on the battery that came with the device or on the company’s website.

Voltage is how much power the charger will draw in the device, or how much is being”pushed” to the device by the charger.  A phone will usually pull up to approximately 5V, though a notebook can pull up to 25V.  A charger must equal the voltage needed by the device.  This is important: drawing too high of 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 fast power is”pulled” to the device, or how much electricity is used by the device.  The quantity of volts will never change, but the quantity of amps that the system pulls may change depending 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 that may be pulled by the device.  In order to exchange chargers, the amp number on the charger must equal or exceed the amp number recorded on the device’s battery. If a unit is paired with a charger that cannot support the amp necessity, it may burn out the power source and kill the apparatus.

So for those who have a modern USB device (smart phone, tablet, 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 may not work with USB interfaces that employ the new Battery Charging Specification.

If The Micro USB  Charger’s Voltage Isn’t 5v…

Some devices may have their voltage recorded 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 plus 5% of 5v = 5.25 volts.  This means anything between 4.75 t0 5.25v is safe to use (so long as the amperage of the charger is equal to or greater than the device’s listed amperage).

An interesting thing to note is chargers supply a higher voltage than the batteries that they charge.  That is pretty much how they operate.  There has to be a voltage differential to produce the necessary current flow in the correct way to charge the battery.  When you look at your vehicle, it has a 12V battery, but typical alternators provide 13.8 to 14.4V charging voltage to the battery.

Stay Away From Cheap Knockoff Chargers

The problem with knockoffs, especially cheap knockoffs, is they often don’t support the power requirements of the apparatus, or aren’t built to maintain a steady flow safely.  Overall, it’s better to stick with the charger designed for the device you are using.

Now You Understand How to Safely & Effectively Swap Chargers

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