Power Banks Important Aspects

The electronic gadgets we are currently using are power hungry. If the necessary power is supplied, these gadgets keep on entertaining us. However, once the battery dies, they become practically useless.  Seeing the “Low Battery Notification” has become one of the most irritating things, especially if you are on a journey and there is no wall charger available.

Tablets, portable speakers, laptops, headphones and many other similar gadgets are in need of a good battery to remain functional. However, the extensive use can shorten the battery life and make it drain out faster. Without energy, all these cool and smart devices are worthless. However, recent technology advancements have come up with a great, portable solution: Power Banks.

You may need a power bank

When your gadget needs to be charged, you can mount it on a holder or plug it in a wall transformer. However, you would physically need to stay next the charger if you are planning to use your gadget while it is charging. With power banks, you will feel tension-free and charged wherever you may go.

Logo printed power banks come in various sizes: from a lipstick size (or pocket size) to paper board sizes (which deliver power boost for days). With the “paper board” type, you can connect multiple gadgets on a single module.

Types of available power banks

The most common power banks types include:

 

  • Universal Power Banks: they are available in various sizes, depending on your needs.
  • Solar-Charged Power Banks: this type includes small photovoltaic cell panels able to produce power if placed in the sunlight. However, we are talking about a rather slow charging method.
  • Old-Chubby Power Banks: this type is old styled and was designed as a phone cover which was fixed on the cell phone. Currently, this type has very limited usage.

Power banks can also be distinguished on a built-in plugs basis:

  • Power Card: this type comes with external charging cables and is extensively used. The USB or charging cables are also supplied.
  • Cable-less: this pocket-sized type includes no external wires and is attached to the cell phone’s port via pin, instead of USB or other.

 The latest available power banks

Currently, there are various Power Banks available on the market. However, we will focus only on a few ones so that you can get a general idea.  

 SOLAR POWER BANKS

Solar chargers utilize energy from the sunlight to supply direct current to gadgets or power batteries.  or to the devices. This technology is based on the photoelectric effect. Solar cells come connected in a series, with the upper side of the cell dominating with negative charges and the lower side being the positively charged plate. When sunlight (or even fluorescent light) falls on the solar cell’s upper negative plate, photoelectrons are generated and travel to the positive plate, thus providing a complete current path.

In the case of Solar Power Banks, the plates of solar cells will supply the adequate current. An intelligent charge controller will sense which source (either the battery or the direct solar light) supplies more power and charges gadgets accordingly. This type of power banks can be either a single frame or multiple folding frames. However, it is important to keep present that this type of power banks is not able to supply much power.

 Main advantages

  • This type of solar banks mostly suits those people who lack access to electrical supplies during long periods of time. People who like hiking can opt for Portable Bag packers which are light in weight and can fuel batteries.
  • Solar power banks are able to fuel smartphones. Depending on the requirement, they can even charge tablets (its engine is rather weak and can’t supply much).
  • Power banks can be charged quicker on bright sunny days. This doesn’t mean that they don’t work on other days. It only means that they are more efficient on shiny days. However, you should make sure the device doesn’t overheat. A temperature raise can damage your phone’s battery. Find a place where it receives the maximum sunlight, then place your solar pack with its plates facing upwards. It may take several few hours to have it completely charged.
  • If there is insufficient sunlight and you can’t charge the power bank, you can choose the USB charging mode and connect it to your computer. Keep in mind that solar power banks are active device themselves, able to produce their own power. It may be helpful to take advantage and power them when you have enough light.

 Disadvantages

  • Solar power banks utilize sunlight to get charged. Nonetheless, if you live in an area where there is less sunlight throughout the year, then it may be wise to opt for a different type of power bank.
  • Solar cells are rather difficult to handle and brittle. So make sure you opt for a shockproof product as well.

These power banks come with super-efficient Li-Polymer batteries which are able to provide sudden current doses and long backup without dropping their own energy levels. They have wider applications and allow you to run several devices simultaneously. They are ideal when camping or when planning to stay during long periods of time without access to outlets. Though they provide bulks of energy, there is one disadvantage: since they are heavy duty, they are rather bulky.
