Things to Consider When Buying a Portable Power Bank

Before buying a power bank, it is essential to know the factors to consider and the hazards to avoid to get the best value for your money while preventing any damage to your device.

  • Check the mAh of the power bank. Getting a power bank with the highest mAh, you can afford means you can fully charge your devices fully more than once. It is especially convenient when you are going for long trips such as camping.
  • Buying a product from a reputable brand can be reassuring when it comes to quality and performance. However, you should also pay attention to the kind of cells used. It could either be Lithium-ion or Lithium-polymer. The good old Li-ion is cheap and easily accessible while Li-poly is more expensive but can provide double the charge density.
  • Another benefit of buying from a reputable brand is that you will be sure that the correct mAh capacity is clear on the label, which also ensures safety. Unlike cheap brands that you can find in the streets, these power banks will not explode.
  • The ports. If you are buying a portable power bank with a considerable mAh capacity, it is best that you buy one with more than one USB port so you can charge other devices at the same time if you have to.
  • Portability. There is no point in buying a powerful power bank if you cannot take it with you on trips because of its size and weight. However, this is also a matter of preference. If you are only getting a power bank in case of a power outage at home or in your cabin in the woods, then go ahead and buy one as big as your car’s battery.
  • Check for the ampere of your devices as well as the DC output written on most laptop adapter before buying a portable laptop power bank. This is for safety reasons as well as to avoid damaging your device.
  • Other features such as an indicator of how much power is left after you charge your devices is favorable. Some use light indicators while some use digital display.

Frequently Asked Questions About Portable Power Banks

How Do You Charge a Power Bank for Laptop and Mobile?

Well, it will not charge by itself to regenerate loss power. You will have to plug it in into an electric socket using the USB cord just like how you would charge a regular mobile phone. Some power banks have a light indicator or a digital panel that shows how much power is left or if it is fully loaded. So the charging time varies according to the capacity of the power bank.

What Kind of Power Bank Lasts the Longest?

Like any of your gadgets, the battery lasts depending on usage. If you are only using your portable charger with high mAh capacity to charge one device while you are on the road, it could last you longer. But if 3 or more people are charging their own devices in one power bank, then it will probably drain faster.

How Can I Know the Possibility of Causing a Power Bank Overcurrent?

Over or undercurrent is a safety issue that you really should look into before buying a laptop power bank and plugging your laptop into it. Always check the label of your laptop adapter side by side the power bank. Some power banks are not capable of charging specific brands of laptops and may cause overcurrent because the DC output current is higher than the power bank capacity.

So, what is the Best Laptop Power Bank?

It is difficult to precisely pinpoint one specific brand or product as the “best” one in its category just because there is no one size fits all when it comes to gears. It all depends on usage and user’s requirements. The best laptop portable charger for us may not be the one for you just because your needs are more demanding than ours.

The rule of thumb when it comes to judging the best product is to assess how you are going to use it. So if you are a businessman who travels a lot, you will need a portable laptop power bank that is compact and light enough to carry with you in your carry on luggage, and one that has a high enough mAh capacity to last you from one airport layover to another.
