How Many Volts Is A Phone Charger

How many watts should my USB charger have?

All-time bargain at: Amazon.com

When checking out the many USB wall chargers and car chargers on Amazon, yous'll meet each device advertising varying amounts of watts. And then how many do y'all demand? It mainly depends on the blazon of phone you take and how many devices you need to accuse at the same fourth dimension.

For iPhones and Android Phones

Most iPhones and Android phones need only 5 watts (five volts 10 1 amp) to charge.

If you need to charge 1 phone, you'll demand five watts.
If you need to charge 2 phones at once, you'l need 10 watts (v watts X ii).
If y'all demand to accuse 3 phones at one time, you lot'll demand xv watts (5 watts X three).
If you demand to charge 4 phones at once, you lot'll demand 20 watts (5 watts X 4).

However, some devices can charge faster with more ability, as we'll discuss next.

For iPads and Tablets

Tablets have larger batteries, so they can use upwards to 12 watts (v volts X 2.4 amps) to charge faster. Some newer phones can too utilise this higher wattage to charge faster too (you can usually find the maximum wattage of your device past looking at the "INPUT" value on the device or in its manual).

If yous need to accuse 1 tablet, you'll need 12 watts.
If you need to charge two tablets at once, you'50 need 24 watts (12 watts X ii).
If yous demand to charge 3 tablets at once, y'all'l demand 36 watts (12 watts X 3).
If you need to accuse 4 tablets at one time, you'l need 48 watts (12 watts X 4).

Quick Accuse devices

If you have an Android telephone that supports Quick Accuse technology, and so you tin charge your phone very quickly if your charger has enough wattage. Generally, Quick Charge draws about eighteen watts (normally at v volts, 9 volts or 12 volts).

For case, looking at the following 2-port Quick Charge car charger, you'll run across it's advertised at 36 watts.

1st Quick Charge Port: xviii watts
2nd Quick Accuse Port: eighteen watts
18 watts + eighteen watts = 36 watt charger

So which should I choose?

If you lot accept simply iPhones (or don't care if your tablet or phone charges a little slower), so yous really don't need to pay attention to the wattage equally your phone will charge at the everyman wattage (5 watts).

If you have several kids with iPads and Kindle Burn down tablets that demand to be kept charged on a long route trip, yous'll want a multi-port charger with at least 36 watts. This would support charging iii tablets at full speed (or a combination of two tablets and i parent's phone).

If you're all about Quick Charge and you lot want your Quick Accuse-uniform telephone to accuse as quickly every bit possible, you'll as well want to await at Quick Charge certified chargers and you lot'll want to look for at to the lowest degree 18 watts per port.
