Types of USB ports
Heloidoe Smart USB Cable for Android/IOS 


There are three types of USB port dictated by the actual current specs (milliamps or Ma).

Dedicated charging port

A dedicated charging port applies to power sources like wall chargers that do not enumerate, so charging occurs with no digital communication at all.

Downstream port

A charging downstream port can be found on a computer or laptop and can supply up to 1.5A, whilst allowing a USB to be detected and begin charging before enumeration (which is when the digital communication takes place).

Standard downstream port

A standard downstream port can be found on a computer or laptop and needs to enumerate (start digital communication) to be USB compliant, however most present-day hardware does draw power without enumerating.

Voltage and Amperage

Not all USB connectors, cables and chargers are equal. For example, some wall chargers can supply more power than others and one particular USB socket on a laptop may vary in power from the others, or PCs with some able to charge whilst in sleep mode.

You will also need to consider Amperage.Chargers increase the current to provide a higher amount of power quickly – this is measured in amps and the more amps means the more power. Therefore, a charger that comes with a smartphone will provide less amps than a charger that come with a tablet. You will need to consider voltage and the equipment you’ll need to use to enable the use of USB chargers when travelling internationally.

Safety Concerns

Uncertified chargers come with serious safety concerns. Similar to unofficial batteries, uncertified chargers can be bought at a reduced price online, from overseas or in high street shops and these kind of electrical products may present a higher risk of exploding or catching fire. Not only do they present a risk to you, the use of uncertified chargers may also damage your phone (which in turn could void your guarantee).

Cheap devices often fail to meet the requirements of the Electrical Equipment Regulations Act 1994. The money that you save comes with extremely high risks and therefore buying a branded/certified charger is essential to avoid often fatal repercussions.

How to Revive a Cell Phone Battery (2) Like Us on Facebook In a previous blog, I introduced a method of How to Revive a Cell Phone Battery. Now I will introduce you another method. Let’s go. Method 2--Freezing the Battery 1. Remove the battery from your phone. 2. Place it inside a sealed plastic bag in addition to a sealed plastic container. This will prevent it from getting wet. Do not use paper bags or foils as water can easily penetrate these materials. 3. Place the sealed battery inside the freezer, and leave it overnight or at least 12 hours. By exposing the battery to low temperatures such as the inside of a freezer, it allows the battery cells to recharge a little, enough to hold sufficient charge to be connected to a phone charger. 4. Remove the battery from the freezer. Allow it to warm up to room temperature. Do NOT use the battery while it’s still cold. 5. Wipe any moisture off of the battery. ...

How to choose a good USB data and charging cable for your mobile phone Like Us on Facebook Most of us will have a few USB data and charging cables for our mobile phone, i.e. one at home, one in office, one carrying together with our laptop, etc. Do you encounter the problem of slow charging, or worst still, unable to charge with the additional USB cable that you bought? Perhaps you can find the solution after reading this. First of all, although most of the USB cables look alike from their external appearance, they might be different inside the cable, and probably that is the ready why certain USB cable unable to charge your mobile phone, certain can charge but at a very slow rate, certain just work as fine as the original USB cable that come with your phone, and certain even can charge faster than the original cable. There are 5 wires inside the USB 1 and USB 2 cables, and there are more inside USB 3.0 cable. Since most of the mobile phones nowadays are using USB...

How to Revive a Cell Phone Battery like us on Facebook When mobile phone batteries have reached their limit or are left discharged for a long period of time, they eventually lose their ability to hold a charge. If your cell phone battery dies, you don’t need to throw it out right away, why not try reviving it first? Maybe all the battery needs is just a little push to make it functional again. Learn how by proceeding to Step 1. Method 1--Jump-starting the Battery 1. First, gather your supplies. You’ll need the following: 9-volt battery—Any brand will do. Electric tape—You’ll need no more than five inches. Electrical wire—Basic thin electrical wire will do. Red (+) and black (-) are preferred. 2. Connect the electrical wire to the positive and negative terminals of the cell phone battery first, as these are smaller. You can identify the terminals of the battery by simply looking at the side of the battery. It will have a plus (+) and minus (–) sign to ...
