Charging 2 Mobile Devices from 1 Charger

In summary, using a Y cable to charge a smart phone and tablet from a single charger with 5.2 v and 2.0 amps may not be efficient and could potentially damage the charger and devices. Each device requires 2.0 amps and using a Y cable could disrupt the charging protocol between the charger and devices. It is recommended to use two separate chargers for each device to avoid any potential issues.

I would like to charge my śmart phone and a tablet from a single charger. The specs are as follows;

Charger = 5.2 v and 2.0 amps
Smart phone battery = 3.7 volts and 3300 mah
Tablet battery = 3.7 volts and 4000 mah

So using a Y cable, will this recharge both devices with any level of efficiency? Will the 2.0 amp tablet charger be adequate to do both at once?

Thanks in advance

Chances are you will damage the charger (and possibly the devices). Each device could easily want 2.0 amps (depends on the device).

Also, sometimes there is a "charging protocol" between the charger and the device, and connecting in parallel could mess that up. There are a variety of signalling methods (could be proprietary or standards based) used to determine charger capacity.

There is always a chance it will work, but it could just as easily burst into flames.

Your best bet is two chargers sharing a wall socket :)

There are 2 (and more) USB port chargers available.
 

FAQ: Charging 2 Mobile Devices from 1 Charger

What is the purpose of charging 2 mobile devices from 1 charger?

The purpose of charging 2 mobile devices from 1 charger is to save space and reduce the number of charging cables needed. It can also be more convenient for traveling or when outlets are limited.

Can any type of charger be used to charge 2 mobile devices?

It depends on the charger's output power. Some chargers have enough output to charge 2 devices at once, while others may not have enough power and could cause slower charging or not charge at all.

Is it safe to charge 2 mobile devices from 1 charger?

Yes, it is safe to charge 2 mobile devices from 1 charger as long as the charger has enough output power and is compatible with both devices. It is important to use high-quality chargers to avoid potential hazards or damage to the devices.

What happens if I use a charger with lower output power to charge 2 devices?

If the charger has lower output power, it may take longer to charge both devices or not charge them at all. It could also potentially damage the devices if the charger is not compatible or of low quality.

Can I charge different types of mobile devices at the same time with 1 charger?

Yes, as long as the charger has enough output power and is compatible with all devices, you can charge different types of mobile devices at the same time. However, it is recommended to use the original charger that came with the device for optimal charging performance.
