Power cells, also called power banks or portable changes, are handy devices that allow you to charge your smartphone or even tablets and laptops on the go. They are extremely useful and unless you are a hermit who rarely leaves the house or uses a pre-smartphone era cellphone, you should get one just in case. Modern smartphones don’t often come equipped with a long-lasting battery and many of us have experienced the fear of the battery dying on us when we are far from home and do not have access to a charger.
Power cells can remedy those fears. Most of them can easily fit into any purse or backpack. And the power cell technology is always changing. The first power banks ever created would not be able to fully charge the newest smartphone even once because of low charging capacity but the latest power cells have no problem charging a laptop.
How to find the power cell for you?
The best power banks can be pretty expensive so it is best to consider your needs carefully before you buy one. What is the device you are going to be charging? Is it just your smartphone or maybe also a tablet or a laptop? Are you the only one who is going to be using the power cell or are you planning on sharing it with your spouse, children, or roommates? Do you need the power cell to last you for a few consecutive days, maybe because you are going on a camping trip? By answering these questions you can try and estimate the charging capacity that will be best for you. For casual use, just in emergencies, a power bank of around 5000 mAh (milliampere-hours) should usually be enough. If you need the power bank to charge your laptop or you are going to be sharing it with other people, the charging capacity of around 30000 mAh will be a much better fit.
What are the maximum size and weight of the power cell that you will be able to comfortably fit anywhere? Bigger size usually means more charging capacity but also longer charging times of the power bank itself so keep that in mind. If you are going camping and will need to use the device every day then you will probably have to go with a larger model even if it will make your baggage bulkier. Or maybe you plan on carrying the power bank in your car’s glove compartment for emergency use so the size and weight don’t really matter to you.
Think about your needs carefully and search for a power cell that fits your own specifications. But do not just buy the first one you see. Look for what other users have to say about the device by reading through buyers’ comments and reviews. For example, this model from Patriot that has a solar panel built-in has a very good rating and will probably be a good choice for most but it still worth it to check out the Patriot Power Cell Review to make sure of its capabilities.
