Black Leather Case plan 

We’ve got a nice suggestion from one of you: make a black leather case.

And we’ve taken your suggestion and started on that! After carefully selecting the leather, we decided to stick it to the original design; the black one would have the same design as the brown leather case.

So, backers with the leather case options can choose the leather color during the survey stage. I will update the pictures when the sample is ready.

Optional 1A Adapter (universal travel adapter CA2 )

We’ve designed an universal charger solution CA2 for CPX. This optional accessory for CPX is designed for people traveling to foreign countries. The multi-AC plug and socket fit more than 155 countries across the world. you can use it as an AC socket converter for your laptop, and also USB charging your CPX or your smartphone at the same time. The size of CA2 is the same as CPX, 1A output.

The idea came to me when my smartphone power ran out on the metro. I dug into my bag for the backup battery, but the backup battery was dead even though I had recharged it just a while ago. Also, the charging cable was no where to be found.

We all had the experience of our smartphones (or tablets) running out of power on the go. Some will choose to buy a backup battery, but it always comes down to choosing between Capacity and Portability. If the capacity is large, the battery will most likely to be bulky; if the size is small, chances are the capacity is also small. 

Another problem with portable batteries is the charging cable. I can’t tell you how many times I brought the backup battery, but forgot the cable. Even if I had it in my bag, chances are that the cable is always in a tangled mess.

We decided that the most compact portable battery with all the essentials integrated is in need. So we designed one.

Production Plan: We have successfully passed the Engineering Validation Test and Design Verification Test, now in the process of tooling. We have carefully selected an overseas manufacturer for tooling. Our team will be in the factory for the Pilot Validation Test which starts in late June. 100 units will be put through the trial run. Upon completion of a successful Kickstarter campaign, we will be able to start mass producing in September.

Risks and challenges

Due to the extremely compact size of CPX, we had to use ultra high density components and figure out ways to integrate everything to optimise the proportion.

To minimize the defection rate during mass production upon successful Kickstarter campaign will require high skills and immense patience.

Our team has a very strong background for design for manufacturing. We have the parts sourcing, manufacturing flow and testing procedures well defined. If the demand is high, we will be able to scale production and logistics accordingly.
