Rex: the mind behind Charmast
As with many other brands of portable chargers, such as Litionite or Ugreen, the birth of Charmast was online, appearing for the first time on Amazon in 2018.
Charmast tells us on its website, in a very relatable way, almost as if it were a story told by a friend, that the idea behind the company foundation was a real-life situation.
Rex -pseudonym of the founder of Charmast- had a business meeting at Los Angeles airport with an important client, so he needed to have a presentation open on his MacBook but his laptop ‘died’ within minutes.
In the meantime, Rex remembered the reasons why he had left the power bank at home: too thick to carry in the laptop case and too ugly for the presentation.
How did the meeting end? Both laughed at the curious coincidence and closed the deal, or at least that’s what they assure us on the official website.
After what happened, Rex decided to ally with a ‘powerful manufacturer’ -whose name we do not know- and invest “millions of dollars” to make power banks thin, beautiful, and compatible with fast charging and multiple interfaces.
In addition, the company did a rebranding in the last year, starting with a radically different logo:
Winning despite being last: the keys to Charmast’s success
How is it possible that today Charmast has become one of the brands that sells the most portable chargers on Amazon despite having arrived much later – compared to others – on the market? This is due to the brand’s philosophy, in line with our times.
Just break down Rex’s description of an ideal power bank in 2018 into parts:
- Slim and beautiful: the aesthetics of portable electronic products have become a central aspect, since they are usually one more element that we integrate into our appearance and, therefore, we want it to give a certain feeling in front of the rest of people (for example, elegance in a formal context).
- Compatible with fast charging: the 21st century is characterized by immediacy and, of course, waiting 2 hours or more for your smartphone to be 100% charged is a thing of the past.
- Multiple interfaces: despite the fact that the USB C port has become widespread, consumers are not exempt from headaches, since there are multiple charging protocols and any charger will not be valid if we want to take full advantage of the capabilities of our smartphone.
Probably a step that this young brand will have to take sooner or later is to start developing its own technologies (e.g. smart charging) so that it can declare itself a competitor not only in sales but also in development and innovation.
