It is a fact that smart phones get quicker with each year that goes by, although it seems that battery life isn’t getting any better at all. Now we know that if we need to keep any device using a USB or a smart phone or tablet on all day, we require a power bank or portable battery packs, as they are also called. There are all kinds of power banks, with different capacities and weights – from the emergency devices as small as a credit card such as for example the Onaji Pawa which gives a super quick charge to your device, to the LimeFuel Blast Pro L240X with hyper high capacity that may boost your smart phone more than 10 times (something which is ideal for camping or even if you have more than one device for charging). In fact, they are not just becoming more sophisticated and with state of the art features, but they are also becoming quicker to charge (thus, quick charging battery pack are the most recent development). In the age of Pokemon Go, this is all good to know!
CAN ANY POWER BANK ACTUALLY CHARGE A PHONE IN FIVE MINUTES?
The answer to this is affirmative, as there are power banks (for example: SUNJACK HEAT BANK ) which can in point of fact recharge their very own batteries adequately within 5 minutes so that they are able to then fill up your phone in full. The speed of their supplying that power to the phone can depend first on the amount of power they can produce, and second, the amount of power a phone is able to accept.
SO HOW DO WE CHOOSE AN EXTERNAL BATTERY CHARGER, ALSO CALLED A POWER BANK?
There are a few factors which are quite important upon selecting a portable charger. The first one is what is called size or portability: a number of of the power banks on the market are light and small enough to put in a pocket, and yet others are huge and unwieldy. Obviously, what you will choose depends on your needs. The second factor is capability or capacity. It should be noted that the power bank you choose to purchase will not match the advertised capacity on the device, as some energy can be lost by means of heat generated voltage change. Unless stated differently by the manufacturer, some 70% efficiency should be expected. Therefore, a power bank advertised for 10000 mAh may deliver only 7000 mAh power. Hence, some of the top power banks render about 90% efficiency. What is also important here is to check the phone’s specification or the battery of the tablet in order to make an estimate of the amount of full charges which can be expected.
Also, the top power banks have the functions of auto-on and auto-off, even though a number of phones support only auto-on. The auto-on function enables the power bank to start with the charging of the devices as soon as they are plugged in, while the auto-off functionality enables the power bank to be turned off them the charge is finished, which means that power is not needlessly wasted.
Some more advice about selecting the best power bank for you: there is in most power banks a sequence of LED lights which are used to indicate the amount of capacity which is left. This works well with power banks that have a smaller capacity, although not so well with those with a larger capacity, as the great leap in power between every LED renders the system pointless. Our advice is to select power banks that have a LCD display which can indicate to you the accurate capacity which is remaining – in this way you are always ready.
What is also featured in power banks are LED flashlights that are built in. This is useful for camping trips, although you should note that you won’t be able to use this device as a torch unless it is fairly portable and it has a design which is ergonomic.
