Buying Portable Power Banks for Your Mobile Devices

A portable USB power supply is a device used to portably charge mobile phones and other mobile devices. It uses portable USB power supply to supply a mobile device with power. It has batteries that are in built and it is in here that power is stored. Power banks are basically made up of a series of rechargeable batteries that are either made of Lithium-Polymer or Lithium-ion cells.

Having a portable power bank for your mobile device is important especially when you travel a lot and have no opportunity to charge your mobile device. Also, it comes in handy if you use your device a lot and have nowhere to charge it.

In order to preserve the health of your beloved expensive phone, you ought to do a little homework before purchasing a battery for cell phone. It is not as simple as going to a mobile phone store and picking out the prettiest bright pink power bank you see.

Features of a Good Power Bank

• Different power banks come with different features and hence different purposes. The most common feature we usually look for is the capacity level (e.g. 4,400mAh, 6,600mAh, etc). The higher the power bank’s capacity, the faster it can charge your mobile device. A good power bank as per the capacity will obviously depend on your needs.

• A good portable power bank provides compatibility with a number of devices. Don't look for one that can only handle your iPhone and not your Windows Phone or your Kindle. Diversity is good as you never know where you will need it and with which device you will need it.

There are numerous other features of good portable power banks. The aforementioned two are the most important, though.

How to Buy the Proper Power Bank

1. Don't buy the cheapest one available

Obviously, it would make no sense to spend beyond your means. However, you should not buy a certain power bank because it is very cheap. Odds are a cheap power bank either has a very low capacity, or it has been built poorly (or with poor materials). The cheapness has to come from somewhere. When going to purchase a power bank, consider the features available with all the ones that are in your price range and compare them.

2. Look at the quality of the battery for cell phone

Quality is usually dictated with the price of the power bank. To determine if a power bank is of good quality, look at its features and (just like in the previous point), weigh those up against the price and compare with other devices. One feature you may want to look for is protection from overcharging.

3. Consider its capacity

As mentioned above, the capacity of a power bank is what determines if it is useful or not. The convenience of the power bank largely depends on its capacity. There is no point in travelling a long distance with a power bank that only allows for a very short amount of charging. Consider your needs and weigh them up against the device.
