What’s power bank?

Power bank is an ‘extra battery’ or an external charger for your phone and other electronic devices. The power bank can be charged via the charger that came with your phone or computer usb cord. The larger REAL CAPACITY, the longer will be the charging time. Different charging methods may result in different charging time as well. Charging with the original charger will be faster than charging with computer usb port. Power banks are popular personal accessories for portable electronics like smartphones or tablets, whose stylishly thin profiles mean limited battery capacities. A power bank is a portable secondary battery that stores energy when alternating current (AC) power is not available. Powerbanks can be branded with your company logo. These portable chargers are a must in the corporate world.

One of the best gifts and souvenirs given as corporate gifts. However, this portable power solution has a great marketing potential.

The relation between the power bank and the promotion of brand is not a difficult one to understand. As the smart phones, tablets,

ipods are most used gadgets. With changing times and fast pace, it is difficult to sit by the charger to charge the gadgets.

These portable chargers come handy, which keeps your corporate and personal life active. Power banks are measured in mAh. mAh means milliAmpere Hour.

Common mistake made by most of the people.

E.g. a 12000mAh REAL CAPACITY power bank can charge a 1500mAh capacity phone for 8 times full?

For a rough calculation of the total charge time, kindly use this formula

REAL CAPACITY * conversion rate * phone battery health / phone capacity = total charge times

EXAMPLE: 12000 x 0.8 x 0.8 / 1500 = 5.12 charge times (0.5-1 times plus minus)

What’s conversation rate?

Conversation rate is the remaining percentage of the battery after the battery lost in heat or PCB operation.

What’s phone battery health?

In simple words, it’s means how ‘healthy’ your phone battery is. Phone battery storage capacity will be lower and lower. That’s also the reason

why our phone can last longer when it’s newly bought than after 3-6 months we used it. Different mobile phone models also will affect the calculation

as some phone drain battery faster than the other.

What’s the different between REAL CAPACITY and MARKETING CAPACITY power bank?

Power banks that Electros sells you is REAL CAPACITY. There are many in the market who sell power bank in MARKETING CAPACITY.

That’s the reason why you will never see any Electros power bank (standard size) have anything with a VERY HIGH CAPACITY at a VERY LOW PRICE ,

its just simple economics. That’s also the reason why a good Electros powerbank of 2200 or 2400mAh model is able to charge more or about the same

as the marketed 3000-3200mAh power bank sold by others.

Anything to do with a battery, will have a chance to explode. No matter if it’s sold by Electros or any other. Chances for a power bank sold by Electros

to explode are near to 0%. With extremely good quality battery and safety standards are Electros’s top priority.

Some power banks in the market have been know to explode because of POOR BATTERY QUALITY & INEFFICIENT CIRCUIT DESIGN.

Circuit design plays a vital role to ensure that a power bank can function properly.Batteries are the most expensive material in a power bank. For power banks, most commonly used batteries are Lithium-ion batteries and Lithium-Polymer batteries.

However, many small brands use counterfeit/recycled batteries in their power banks. While this enables them to supply power banks at a very low price,

these power banks carry severe safety risk.A good circuit design also allows the power bank to be well equipped with multiple circuit protections such as high

temperature, overvoltage as well as short circuit.

Power banks have been know to explode catch on fire and even burn up your phone or tablet. because of their poor manufacturing quality and standards.

This is one of the reasons airlines are now taking extra measure when its comes to lithium-ion batteries and devices that contain them.

To sum it up, We at Electros are focused on providing ONLY THE BEST.
