For travelers, there are many devices that can meet their charging requirement on the road, including power converter, travel power strip, etc. When you only have some mobile USB devices, in fact, what you only need is a universal multi-USB charger which can provide several USB ports for your devices and can work for international voltages ranging from 90V to 220V. It is also easy to take a compact USB charger in your bag and start a relaxing travel. If you’re looking for the portable and functional USB travel charger, here you can get something to help you choose a right one. 

Voltage of the USB charger

Many USB charging device has marked its compatible voltage and current cleanly on the surface. Rated voltage and power are important for smart phones. Low voltage will make it slower to fully charge it, but high voltage will bring damage to cellphone battery or components, or even threaten your safety. There are mainly five standards of USB charging voltage or current.

USB 1.0/USB 2.0: 5V/0.5A

USB 3.0: 5V/0.9A

USB Battery Charge 1.2: 5V/0.5A, 5V/1.5A

USB Type-C: 5V/0.5A, 5V/0.9A, 5V/1.5A, 5V/3A

USB Power Delivery 2:5V/2A, 5V/1.5A, 12V/3A, 20V/3A, 20V/5A

Different mobile devices need different standard voltage and current. It seems easier to charge Apple models because they only require two charging outputs, 5V/1A for iPhone and 5V/2.1A for iPod. But at present, most of the mobile devices support 5V/0.5A and 5V/1.5A. Before choosing a USB charger for travel, you’d better make it clear what the rated voltage and current it has. 

USB charging stations

Choose a USB charger that has enough charging outlets in case that all your gears need to be charged at the same time. But it doesn’t mean the more the better. More USB ports will increase the occurrence of overheating especially when it is made of inferior materials. That is because the multiple ports are distributed closely and the heat they generate together will accumulate to a high level, thus easy to cause damage or fire. Too many ports also mean large size. For traveling, a slim device may be better. So, choose a charger with adequate USB ports based on real needs and materials. 

Other things you should know about a good USB charger

Many details should be taken into consideration when you select a USB charging device. What is the length of power cable? Long cable allows you to power and play more freely in a wider area, so you don’t have to stand and wait around the corner for your cellphone. Does it have an independent switch? Some USB devices are designed with independent switch to control power and safeguard your devices when there is power issue. Do you want a special USB charger? Some charging devices come with a special placement for mobile devices in charging. Some are designed with a LED display to let you know the charging status of your device. Choose a charging device that is both useful and special.
