How to choose power bank for your phone and tablet?(2)

In a previous blog, we do not finish this topic so let’s continue.

Fourth: your power bank will come with a cable.

A cable to charge the battery: YES

Every power bank should come with one cable (usually a standrad USB to Micro-USB cable) to charge the power bank itself, which you use to connect the power bank input port (usually Micro-USB) to a standard USB wall charger.




A cable to charge your phone/tablet: MAYBE

If your phone or tablet connects via Micro-USB, you can use the supplied cable to charge it.

If your phone or tablet connects via a Lightning or USB-C connector, you will need to use an additional cable to charge it. Some power banks come with multiple cables and you could check the packaging to see what’s included.

Some power banks provide cables that are detachable, which makes it easy to switch between cables for your iPad, your Samsung phone, your Kindle or another device.

Some have cables that’re hard-wired to the battery that they cannot be detached, making them easier to find in a low battery emergency, but may make them less versatile overall.

Some even have clever storage solution: a detachable cable you can switch out for other cable, plus a way to keep the cable close so it’s always close at hand.

Fifthly, it’s about charging the power bank itself.

Unfortunately, no power bank has been invented that magically recharges itself when it’s empty. But on the whole, they are pretty simple to charge: plug the supplied cable into the input port on the power bank and a standard USB on the other end into a wall charger or other power source.

Power Bank input ranges from 1Amp up to 2.4Amps (short for ampere and it’s a unit of current). Put simply, the bigger the input number, the faster it will recharge.

Some power banks have an LED indicator, which tells you how much power the power bank has left and on the other side will tell you when you need to recharge the battery.

What’s more? Here’s something about how to choose a safe power bank.

It’s easy to avoid counterfeit and dangerous ones by following these simple steps:

Register Your Device   some power banks require you to register your purchase, by providing the serial number either online or via a helpline. This is a good way to activate your returns policy and to ensure your product is not a counterfeit.

Check the Warranty   manufacturer, country of origin and the type of battery may mean differences in the type or duration of the warranty. If you are unsure, check the small print on the package or the instructions provided.

Something else? Surely. The Importance of Quality.

Safe power banks should have undergone the following testing.

Efficiency   more efficient power bank is, a lower operating temperature it will have, which wastes less energy for a longer life expectancy.

Over Current Protection   it prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.

Over Voltage Protection   it protects both the power bank and the connected device by keeping the voltage within recommended safety parameters to avoid damage.

Over Discharge/Charge Protection   some power banks consistently monitor charge states to prevent this from happening.

Heat Tests at Extreme Temperatures   While using batteries in extreme temperatures isn’t advised anywhere.

Last but least, it’s CERTIFICATION.

These logos or marks, usually found on the packaging, will indicate that they have passed the necessary industry standard regulations, to comply with and achieve the following certifications.

So, have you got a clear idea about how to choose power bank for your phone and tablet while reading through the passage?

HOW TO FIX A PHONE THAT WON'T CHARGE PROPERLY(2)
A previous article is about the first 6 steps of How to fix a phone that won’t charge properly.
7. Charge from the right source Charging from a wall socket will always be faster than charging via PC or laptop, because computers' USB ports don't deliver very much power. A wall socket can deliver twice as much power as a USB port, and fast chargers it can deliver as much as five times the power – which means much, much faster charging. So if your phone is charging slowly and you're connected to a laptop: there's your problem.

If your wall charger doesn't appear to be delivering the goods, check that it's appropriate for your device. A charger from another phone might not deliver the right amount of juice — for example, a charger for a Bluetooth headset won't put out as much power as one designed specifically for smartphones. In the case of recent high-end phones, you might have a phone that supports fast charg…
Your buying guide for the best power banks in 2017

Your guide to the latest and best power banks of 2017. What is a best power bank? It should have some innovative function and it is just what you need. Phones get faster every year, but the more powerful they become the less their batteries can keep everything going. And, of course, all batteries will degrade over time. If you need extra battery power for your smartphone, tablet or other USB-powered device, you need a power bank. You might assume all power banks are much the same thing, but you would be wrong. You can get compact power banks that will charge your phone once, slightly larger portable chargers that might offer two or three charges, or high-capacity banks that can charge your phone in excess of 10 times! Working out how many times a power bank will charge your phone depends on more than the mAh rating on the packaging. No power bank is 100 percent energy-efficient, with every portable charger losing power through voltage c…
