HOW to Choose a Good Power Bank?

11 March 2015

Tags: , , , ,

In this digital era of smart-technology, battery standby time seems shorter.  Is your smartphone, tablet or other digital devices often out of battery at times you needed them most?

Power bank – a portable power supply – exists to solve such inconveniences.  Choosing a power bank involves consideration on safety aspects but many people are still unsure on how to choose a good power bank.  Which brand is better?  Which power bank is safe?

MAIN FACTORS TO CONSIDER WHEN CHOOSING A POWER BANK

1st – SAFETY

Safety Factor

Safety is the top priority when choosing a power bank.  Take note of the electronic products certification for power bank.  A power bank with relevant certifications indicates its compliance to the required standards.

 

 

 

 

2nd – BRAND

Brand Factor

Word of mouth from the public influences a brand’s reputation the most.  Apart from that, branded products are normally certified by relevant authorities – the production processes and manufacturing technologies are relatively safe and verified.  Whereas off-brand products produced with substandard materials and incompetent skills will easily go wrong to the extent of causing explosion especially on electronic products such as power bank that emits heat while in use.  Therefore brand and reputation are important factors to consider when choosing a power bank.  Moreover, “brand” is also an assurance for after-sales service.

 

3rd – CAPACITY

 Capacity FactorDue to the limitation in battery’s technology, the highest capacity power bank in the market at this point of time does not exceed 23800mAh because the higher the capacity, the bigger the size of the power bank.  But we often see power banks labelled with capacity of 30000mAh, 50000mAh, 60000mAh and even 100000mAh – selling at cheap prices and selling well!  If these power banks are really being produced at all and produced as per the capacity printed on the label, the size of the power bank should be no smaller than a milk carton.  When you see a small power bank labelled with high capacity, please beware of bogus product, it could be a time bomb.

 

 

4th – PRICE

Price Factor

The price range of power banks in the market is relatively transparent.  If a power bank price vs capacity differences are too obvious, the power bank is either bogus or the seller is dishonest.

 

 

 

 

 

5th – BATTERY CELL

Battery Factor

Many power bank explosion incidents are caused by internal battery cell short-circuit.  Therefore choosing a power bank with good “core” (battery cell) is crucial.  This is distinguishable from the price of the power bank.  Battery cells that explode are usually those of used and recycled battery cells hence much cheaper than new and good quality battery cell.  It is inadvisable to purchase if the price difference is too obvious
