STACK

Modular Surge Protector

Custom Power

STACK is a modular outlet surge protector that you make into precisely the right size.

Snap modules together to charge and protect exactly the number—and type—of devices you have. Simply add or remove modules depending on how many devices you need to charge.

You start with a power base that has three or more outlet modules and
an additional end connector piece. Add different modules to it—from circuit breakers to USB chargers and even Ethernet adapters.

Each module type is color coded to make it easy to identify. They all have enough surface area so you can fill up the whole strip and your devices won’t have to compete for space.

Serial inventor Michael Ma was choosing between a power strip that had the exact number of outlets for his devices, or preemptively buying a longer one. That’s when his “choose your own configuration” idea came to life.

From now on, your power strip will be exactly the right size and setup.

    Hi I'm Michael Ma, and looking forward to telling you more about our newest product, the Stack surge protector and power strip. It's finally modular, so you can make it work for your own situation more easily.

    Can you connect the pieces so that the 3-pronged blocks can point in alternate directions? That would be very useful for large transformer plugs.

    @Debra Hi Debra, The pieces can connect in a set order in order to operate. We are already working on new modules which are due to release next year, please be rest assured that all future modules will be backward compatible.

    thanks,

    The description refers to adding an ethernet module. What's that, what does it do, and when will it be available?

    Hi Ivan, the ethernet module is Telephone/LAN module. It's a surge protection module that lets you connect an internet router, modem, telephone, fax machine or anything else that uses the RJ11 or RJ45 socket.

    How many extensions can be safely added and still operate correctly? For an example! in my classroom, I have 6 or more computers with limited outlets. Could six or more blocks together be safe for my students and my computers?

  • Michael
    Michael – Special Guest
    10/11/2016 10:49 AM

    @Jeremy Hi Jermy, According to ETL recommendation, no more than 6 additional modules (1 x 3 outlet extension module count as 1 module, 1 x USB charging module count as 1 as well) should be added to STACK.

    Thanks,

    Michael

    10/11/2016 11:09 AM

    @Michael So if my math is correct, we can safely connect 6x 3 outlet extension modules, which add up to 18 devices?

  • Michael
    Michael – Special Guest
    10/11/2016 11:13 AM

    @Jeffrey

    Technically, yes! Stack got a build-in over current protection circuit that would cut off the entire system if the connected devices are consuming over 15A of power.

    thanks!

    Hi--I looked but cannot find if there is any sort of warranty for items connected to this protector. Do you have any sort of warranty? If so, what is it. I am meaning the kind that protects my computer ect in case of power surge if your protector does not work.

    @Angela Hi Angela,

    Our company does have a US$1 million product liability insurance in place. We are looking extending it into equipment insurance as we move forward. All our products have 1 year limited warranty.

    So, I actually think this might be useful for me when I travel internationally. I am most interested in the added Dual USB Charging module, and wonder if I could detach two of the four plug outlets, and add the USB module?

  • Michael
    Michael – Special Guest
    10/11/2016 11:02 AM

    @Sara

    Hi Sara,

    The first 3 plugs are fixed and cant be detached. The entire concept of STACK is around flexibility, and we are developing new modules that would fit exactly what you are looking for which shall be ready next year.

    Please be rest assured that all new modules will be backward compatible. You may purchase STACK now for home use and then add the new modules next year for travel.

    thanks,

    Michael

    Is this UL listed? also some advice for your customers, a surge protection device is simply one layer of protection and for a comprehensive surge protection plan, you should have a whole house surge protection device installed at each electric panel AND then use the surge protection devices on all important devices and appliances.

    STACK is ETL and cETL approved.

    Please note ETL and cETL is just as widely recognized as UL. As least by major retailers in N. America. All tests conducted under ETL & cETL complied with UL standard as well.

    The speed of charging devices depends in part on the adapter. How fast is the charging of a device (for me specifically a Galaxy smart phone) in the USB adapter compared to the standard issue Samsung charge adapter? Does this change if both USB ports in the block are used?

  • Michael

    @Bruce

    Hi Bruce,

    the USB charging module supply continous 3.4A of charging power and max output of 4.0A. it would be able to charge 2 iPads at the same time at full speed. So I don't foresee any charging speed issues with SamSung phones.

    thanks,

    Is there a cover or cap for the last module to protect the connector slot? It should be provided to protect anyone from electrical shock, and to protect the modules from anything that could get into that slot.

  • Michael
    Michael – Special Guest
    10/11/2016 12:31 PM

    @Ronald

    Hi Ronald, the end module only got connector slot on one side, the other side is absolutely closed with the plastic casing to prevent any chance of electrical shock.

    All female connectors got safety shutters which can only operated by the STACK patented mail connectors.

    Thanks,

    I can't tell what the first comment is asking, so this might be redundant, but here goes. It would be really useful (and frankly not very useful without) if some of the 3 prong AC outlets were rotated 90 degrees to accommodate power converters that are oriented that way (and many are). Is that at least on the drawing board, if not coming soon?

    You should have replaced one of the plug spaces with the USB block, instead of having to pay to add on one of these.

  • Michael

    10/11/2016 2:10 PM

    @Bill Hi Bill, We think that would defeat the purpose of modular concept in customization. That also allow us to enter a lower price point.

    Thanks!

    @Michael it's not a lower price point when you have to pay for them separately.

  • Michael

    10/11/2016 5:27 PM

    @Bill hi bill, yes, definitely. the USB block got continuous 3.4A charging power and max out at 4.0A. That means it could charge 2 iPads at the same time at full speed without problem.

    thanks!

    @Michael It would be nice to have a custom build ordering section. I nave a need for one of these but only require two 3-prong and 4 USB blocks.

  • Mike
