10 points to notice before buying a powerbank.🤔🤔🤔

Hello friends,
These days purchasing a power bank in market is very common, but increasing power bank manufacturing companies and power bank in different price will get consumers confused that which should they buy ?
Today, i will tell you some points by the help of which you can purchase a power bank very easily.

• Why users need Power Bank ?
  The smartphone phones size was decreases day after and on other hand the performance was also increases therefore our smartphone battery can't give us high usage time and our usage pattern was also increased.
  Due to these reasons our smartphones want some extra power which these power banks provide it.
  Power bank allow a smartphone user to give power to smartphones portably whenever, wherever they want and use their smartphone again.

• Why users faces problem while purchasing a powerbank ?
  Market was really expand and competitive in powerbank department in different price range, power capacity, companies design etc. That's by users face problem while purchase a powerbank.

These points may help you to purchase a power bank by user points of view.

• Capacity : - In power bank department anyone can get a powerbank from 1500 MAH capacity to 30000 MAH capacity.
  Here i would prefer user to choose a capacity which user think they should have.

• What should you prefer a portable powerbank or more recharge cycles ?
  In my opinion if you want more charging time but also want portability then choose a average capacity powerbank from 6000 MAH to 15000 MAH.

• Pass through charging : - Powerbank companies not provide any adapter or charger with powerbank.
  Then we only get one adapter which was our smartphone adapter.
  And user will also don't like to carry two adapter one for smartphone and another one for powerbank.
  Then, powerbank having this facility of pass through charging allow user to connect powerbank with adapter and connect smartphone with powerbank.
  By this any user may solve problem of discharged one device.
  Sleep on night by connecting device as given above then adapter will first charge user's smartphone then the powerbank on morning you will get both device charged.
  This feature was not available on all powerbank. For ex. - Some xiaomi's powerbank have this feature but oneplus's powerbank don't have this feature.
  With this feature user can charge two device with one adapter.

• Protection : - As we know the powerbank have very high capacity battery. Then carrying such powerbank on pocket and bag was also very risky, therefore protection is also very big point.
  Big Powerbank companies such as xiaomi, oneplus, sony, HTC, Huawei, Lenovo, samsung, anchor etc. gives a user four types of protection.
  1 Overcharging.
  2 Overvoltage.
  3 Short circuit.
  4 Excessive temperature.

User having these protection by company then user can carry such powerbank anywhere.
That will never harm user's smartphone or powerbank.

• Output ports : - The powerbank have different number of output ports, some powerbanks have one output port, some have two and some have three or four output ports.
  Now, this should be over users requirement.
  User may want only one port to charge his own smartphone or device or may want two or more for charge more than one device.

• Output current and voltage : - The powerbank having one, two or more output ports may have different output current. ie. 1 AMP or 2.1 AMP.
  Or have same current. ie. 2.1 AMP on both or 1.5 AMP on both.
  High output current may give us fast charging if our device support it.
  Output voltage should equal to the adapter voltage of device. That may be 5.0 volt or 5.1 volt.
  User should check the output voltage and output current that will fulfill the requirement of user or not.

• Quick charging : - As we all know many smartphone on market was come with quick charging capability.
  Now this feature was also come on powerbank.
  Some powerbank have high capacity but not charged often in full day, So this feature was also very good for heavy users. They can charge their powerbank with a Qualcomm quick charger.
  Some powerbank having quick charging for input and output both. This feature will also help user by this user can charge their device quickly with power bank and they don't have to carry two devices and USB pin all the time.
  User can check this feature on specification while pucharsing a powerbank.

• Utility : - Some powerbank have user friendly utilities such as torch.
  Torch can be used on camping.
  This led torch consume very less power.
  Some powerbank also have bluetooth speaker or FM/radio on it.

• Brand : - As of my experience on powerbank brands xiaomi is best on powerbank.
  Huawei powerbank of 13000 mah is also good.
  One plus powerbanks are also good but it do not have pass through charging feature.
  Ambrane powerbank of 13000 MAH is also good.
  Sony powerbank.
  Samsung powerbank.
  Hockey powerbank.

You can also choose from any reputated company.

• Connectivity : - Some powerbank provide inbuilt charging cable.
  If you don't want to carry a USB cable or don't want to purchase a additional USB cable for powerbank then try to purchase a powerbank having inbuilt USB cable with it.

Some most important points : -

• Conversion loss : - Suppose your device battery is 2500 MAH and your powerbank battery is 10000 MAH then it can't charge your device 4 times.
  Companies says right its capacity is 10000 MAH but
  Each time your powerbank charge your device for converting its power it losses some energy due to which its efficiency decreases from 10-25 %
  Then, if you charge your 2500 MAH battery by 10000 MAH powerbank it will charge your device 3 times if its efficiency is 75 %
  Different companies powerbank gives different efficiency. For ex. - Xiaomi powerbank have good efficiency.
  Conversion of power always losses some energy.

• Best performance : - The maximum output from a powerbank cannot be analyses instantly whenever you purchased.
  The powerbank will give its maximum or peak performance after 8-10 recharge cycles (charge-discharge)
  Its peak or highest performance cannot be judged on 1-2 recharge cycles.
  For stable output user have to wait upto 8-10 recharge cycles.

• Never do this (advice) : - Powerbank market is also very expand like android device market.
  Here user can get any type of powerbank and their deals.
  Many local brands and market sales there powerbank on very cheap rate.
  Purchasing such garbage is like wasting your money.
  These powerbanks not give user a good value for money experience.
  In local market powerbank of 30000 MAH, 50000 MAH can be purchase upto 1000 Indian rupees but its just wasting your money because these powerbank only have capacity sticker on its packing.
  These powerbank never give such capacity, reliability and stable output.
  These powerbank can also harm your device.
  User should only purchase from a reputated company.
  And some time user may also get some offers on Flipkart ie. Powerbank on cheap rates.
  Sometime fake powerbank of xiaomi, sony, samsung etc. may also get on cheap rate was also fake. It is just wasting your money.
  I was recommend you to purchase a powerbank from reputated site and brand. You can also check user rating, user comments about quality and warranty.
