The first question that must arise in your mind is what exactly to look for when purchasing a portable smartphone charger, right? Well, that is a great question, and we will discuss it thoroughly as follows.
Things to Consider When Buying a Portable Phone Charger
The capacity of a portable smartphone charger is described as the number of times it can charge your mobile phone completely. It is measured in milliampere-hour (mAh) and is the same unit that measures the capacity of your mobile phone’s battery. If your mobile phone has a battery of 2000mAh, and you buy a portable mobile charger of 20,000mAh, then it can charge your phone roughly ten times.
That isn’t so black and white, though, power losses due to the conversion of voltage and circuit resistance result in a little lower capacity than mentioned. Nonetheless, this metric is used to ascertain the number of times the portable charger will be able to charge your phone.
As the name suggests, portability is rather a seriously important characteristic to a “portable” phone charger. Although these power banks weigh quite less and are sized to fit a palm, in most cases, there is still quite a lot of variation in their weights and sizes. Power banks with more capacity tend to pricier and heavier, but that is not always the case. As we will see in a while, many of these portable phone chargers are light as a feather and have huge capacities.
Amperage of a portable phone charger decides how fast it is going to charge your phone. You must have found yourself in a position where you plug your iPhone with a cheap charger, and it takes ages for it to charge, right? That is because of cheap wall chargers and low-quality power banks do not have enough amperage that is required to charge your phone or tablet with efficiently, or faster.
Power bank or portable battery manufacturers usually ship them with 0.5A, 1A, 1.5A, or 2A of amperage. Which one is better for your device depends on your particular device. Most tablets, for example, require a 2A output charge their batteries at a fast speed.
4. Recharge Time
All these portable smartphone chargers need juice for themselves too naturally – that is the only way they can charge other devices. A big concern for these portable chargers is how much time do they require to recharge themselves fully? A portable charger is useless if it takes all day to restore itself.
It goes against the basic idea of having a portable charger. So we have to take into consideration this factor seriously before buying a portable charger.
Portable smartphone chargers are dominating the market and are the go-to accessory for most smartphones owners that spend most of their days outside homes. It is an incredibly impressive invention to keep people connected and never lose to the daunting accidents of dead phones and minimally charged gadgets. We think everyone who deals with important lines of work and has to be on the field should own one of these. Moreover, it is an inexcusable necessity for travelers.
A perfect portable charger would be able to give you at least 5000 – 20,000 mAh capacity and should be lightweight. Another important factor is you should always buy a charger that has an IC or is intelligent enough to recognize your device’s optimum current, only then will it be charging it at reasonable times.
Anything else will leave you in turmoil of agonizing wait. It will test your patience. Having security protection against short circuits and power surges should be preferred. After all, your smartphone is your ally, and you do not want to let it down.
