About our team

After finishing my MBA in Dublin, Ireland, I found there was huge demand for smart phone accessories that were both aesthetically pleasing and useful. That’s when Diven, Joy and myself found each other, and created  one company to design and manufacture gadgets.

Forcharge is trying to provide the best gadgets and keep them Simple & Portable. We focus on charging stuff like: Portable Charger, Data Cable, Battery Case, Wireless Charging...


Where We Started?

We started to develop the Blade4000  in 2013 since we launched the 3-in-1 keychain charger in Berlin. The keychain charger was a data-cable, flash drive and charger all in one. . With the success from 3-in-1, we kept hearing the same question: What about my iPhone?

In 2014 Apple opened the window for external memory storage (OTG). However they still prohibited any external flash memory. But we heard you the consumers and your need for more space.

Where the fund will go?

We already have 10K C37 in stock (female Lightning connector) and corresponding chips from Apple’s authorized supplier. The tooling will start with no payment necessary as soon as we pass our goal thanks to our experienced supply chain relationship and control. Now, we are investing in MFi testing, PCBAs, and Battery cells.

Risks & Challenges

We have been at work on Blade4000 and have developed several versions of App and found what works perfect samples for the latest iOS system. The next step for us is to devote securing the MFi certificate which is always tough.

Although we have enough experience on simple portable charger and iOS flash drive, we are pioneering the combination of both power and OTG flash memory.. Samples are working perfectly. MFi approval is our biggest issue due to Apple's fussy rules.
