Power banks are now one of the most popular promotional items in the world. The sad reality is that there are many unscrupulous people who are importing inferior quality power banks into South Africa. In certain cases its companies that simply do not know any better.

We have created two Brand name power banks, Gadmei and Powercharge. This is a little unconventional for promotional power banks yet we have done this for a number of important reasons:

  1. It’s in line with recently implemented SA national regulator for compulsory specification requirements that all power banks should have identifiable markings nrcs.org.za
  2. We meet specifications and safety test reports required by law in South Africa
  3. If there is a problem with a power bank we can verify that it is ours
  4. We are proud of our quality and safety specifications

We have taken extreme measures to ensure our power banks are as safe as possible. These measures include:

  1. Ensuring all our models have safety test reports for both the power bank as a whole and the battery cell itself.
  2. Using a single ISO9001 accredited factory to ensure quality throughout the manufacturing process.
  3. Confirming CE certification
  4. Confirming RoHS compliance
  5. Accepting only test reports from highly reputable testing agencies. In the case of our power banks, SGS.

It’s very common for Chinese factories to claim to have all sorts of certification. The fact of the matter is that very often this certification has no relevance to safety testing or safety specifications that a power bank should have.

Our promise to you
Gadmei or Powercharge brands of power banks with the www.powebanksafety.co.za web site printed on the packaging have been manufactured to the highest possible safety standards. We can assure you that:

  • We have carefully checked our factories certification and safety test reports.
  • The batteries used in our power banks are from a top manufacturer in China. This factory is also ISO9001 accredited and has all relevant EN and IEC safety test reports.
  • We comply with the South African Nation Specification requirement. (SANS Act)

Warranty
Our power banks are sold with a 1 year replacement warranty.

FAQ’s

Can power banks explode?


We do not have any proof of actual explosions but there have certainly been many severe meltdowns of Lithium batteries.  These meltdowns could be accurately described as a rapid self combustion of the Lithium cell at extremely high temperatures.  Even top brand names have had problems with Lithium Ion cells in their laptops and mobile phones.  For this reason it is extremely important to deal with a reputable power bank supplier who only uses top quality batteries and electronic circuits.

What’s the difference between Lithium Ion and Lithium Polymer batteries?

Lithium Ion, also known as 18650 Lithium Battery cell, is an older generation battery which is still the most commonly used batteries in lower capacity power banks. This is mainly due to their low price. This low price has also resulted in them being increasingly used in electric vehicles. Lithium Polymer is a more advanced battery with higher specs and provides higher level of safety features, they are therefore more expensive than Lithium Ion batteries.   Despite the higher price, It is advisable to go for Lithium Polymer Power Banks especially when it comes to higher capacity power banks.

What causes power bank failures?

There are three main causes of power bank failures:

  1. Poor Battery Quality
    Batteries are the most expensive part of a power bank. Power banks most commonly use Lithium-ion and Lithium-Polymer batteries. In order to reduce cost, many Chinese factories use counterfeit or 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 risks.  It is the battery itself that self combusts after short circuiting when a power bank explodes or melts down.
  1. Inefficient protection Circuit Design
    The circuit design plays a vital role to ensure that a power banks function properly.   High quality circuit design and high quality electronic components allow for multiple circuit protection systems.  These include high temperature detection and protection, overvoltage protection, over discharge protection and short circuit protection.
  1. Mishandling or Improper Usage
    Power banks are electronic items and are susceptible to damage by people mishandling them.  Similar to any product containing a battery and electronic circuits they should not be:

    • Crushed
    • Thrown into fires
    • Expose to water or high humidity
    • Dropped
    • Purposely short circuited

Having proper circuit design, safety measures, testing and tightly controlled quality standards can greatly reduce the risk of battery failure.
