Wow have never used the 2.1 amp output in charging my device before. Because I was told it's only for tablets. No wonder my phone does not, charge fast.changed up to five chargers thinking they were fake and as such the USb not giving my battery the right amount of charge. Had even planned getting another charger today sef. God bless u op.

DlawTECHY:
Portable battery chargers, better known as power Bank have become a great utility for Smartphone users as it not only helps to keep your devices charged up while on-the-move, but also because they in spite of being handy and portable, can charge your Smartphone and tablet multiple times depending on the capacity.



You have to consider some salient factors such as:

1. Power Output:

Your power bank capacity doesn’t matter as much as the power output of a power bank .The most prime reason for buying is to charge your device and if fails to do that right, it just as good as a plastic box.All devices which people use needs at least 2 Ampere to charge it .So before buying a power bank check, at least, one of the two output ports has a 2.1 Ampere output .

Many people complain that while charging the phone the battery percentage still decreases.The answer is simple if your rate of charging is lower than the rate of discharging the battery percentage will decrease and may also reach zero and the phone might switch off.

Advantages of high-power output power banks are:-

Phone charges quickly
Usage of phone and charging can be done together
Rate of charging is always greater than rate of discharging of your phone.

2.Type of battery cells

Li-ion and Li-poly are nothing but two variations of the battery cells which are popularly used to constitute the best power banks. Most of the battery packs go for the Li-ion as they are cheaper but portable chargers being constituted with Li-ion tends to become much bulkier in comparison to the Li-Poly.

Not only Li-poly, being sleeker, can provide the provision to the manufacturers to manipulate the size and shape of the power banks further, they are safer in terms of usage as well. A Li-Po Battery can also retain its charge longer.

3.Power Capacity

The next important thing you should consider is power capacity after the above two.This depends solely depends on what devices you are using.The power bank’s capacity should be at least 2.5 times your phone’s capacity to get 2 full charges out of it.Only 70% of a power bank’s capacity is usable .

For example, If i buy a 9,000MAH power bank to charge a phone with 3000MAH battery .The usable power I can use is just 6300MAAH which will only give 2 full charges, not 3 as per expectation.

4.Weight and Form Factor

The power bank is also called a portable charger so you would want to buy a portable and not a bulky one.Not all power banks are really portable to carry around.If you always carry your power bank to where ever you go you should consider a light power bank with a sleek design. Everyone wants a power bank that you can carry about at all time.

5. The number of USB ports

Number of ports on a Power Bank plays the vital role if you are going to have a need to charge multiple devices simultaneously. Usually most of the portable chargers below 10000 MAH capacity (smaller capacity) do not come up with multiple output port option. The reason is obvious; they are simply not large enough to charge up more than one device at a time.

By the way, it is important to know the number of output ports of a power bank affect output current when charging multiple devices at the same time. To get more clear about this, let’s take the example of the Mi 16000MAH power bank, which comes with two USB output ports (whereas the 10400MAH variant has only one output port) and claims to charge devices (Smartphone or tablet) at 2.1 A at 5V.

However, this claim is only true when charging only one device at a time. When you use both ports at the same time, this particular power bank is capable of providing at max 3 A at 5 V (i.e. 1.5 A per port) instead of otherwise presumed 4.2 A. So, before picking one battery pack, especially if fast charging is a priority to you, then this aspect should be taken care of scrupulously.

6. Buy from respected brands
Never become excited at power banks selling extremely cheap especially when they are unbranded, where those power banks not only failed to charge the phone, but also damaged the devices severely.

So be careful while balancing between quality and price, when particularly it comes to a power bank. Some good brands of power bank include jakery giant, lumsing power bank, romoss, veeda etc.

The truth is that most solar power banks are fake. They take forever to charge while they drain so quickly

That's why I bought it from a popular online store, seems I wasted my money,wanted to use it to try the credibility of online products seems they are all same

tosyne2much:
The truth of the matter is that when you charge it with sunlight, it take forever while the battery diminiahes quickly unlike when you charge it with a charger

BTW, how much did you buy it?

DlawTECHY:


Not all online products are fake. There are different sellers online and so with different products.

#7450, and obviously will be my last time to patronise them, I only thought they will be more credible

Just manage it you hear?

2dugged:
why allow a supplier with substandard product use your platform to sell fake products to customers?, it's only a daint on their reputation not the supplier, my own concern is I paid my money to the only retailer not the supplier, so I don't funding care who.the supplier is,anyway, the online store has been flagged,my fist and last time of buying form them, all this online stores are no different from shops we go to

tosyne2much:

DlawTECHY:


I get your point. You need many people try to sell their product on the platform and its not really so easy to check all products that are being sold there..
But I advice you when buying from an online shop , buy from the shop directly. E.g when buying from Jumia you can buy directly from humus and not from other stores in jumia. It's safer and better that way.

DlawTECHY:


Most solar power banks are fake. Some of them the light reflecting that it's charging under the sun is actually not connected to the so called solar power bank. The light will just shine when under lightning condition. That's why if seems to charge like forever. There are actually some great solar power banks though.. Will drop recommendations too.

I'm inclined to agree with you sir... The light that reflects under any slight lighting condition is usually fake. The light only deceives you

2dugged:
how the hell am I supposed to know who is who?,I went to their website and made an order and paid to them, Abeg don't vex me

DlawTECHY:


Not trying to vex you. But you can open jumia website on your device and try purchasing. You going to see the seller details.
If its jumia then it will be written there but if it's other stores it will also be written there. That's what I mean.

2dugged:
I used konga, I can see where you are going, both jumia and Kong have been flagged, as far as I am concerned, I suspect you work there too, so Mr, just leave it at that

I used to get very reliable powerboats from Slot and Habeebpain here on NL. I have bought over 4 reliable ones from them (aside from the two I got for my dad)

Nice one op
