Gave as a gift.


Gave this as a gift to my son. He was very impresses.


extension to main unit


It is hard to remove the end piece to attach to the main unit if you want to extend it. It works fine otherwise. I like the design and occupies much less space on my desk than the usual type of unit. Thank you.More > < Less


Not as flexible as it appears


There are a limited number of legal combinations--you must have the cord unit, you must have at least one middle section, and you must have an end unit, so all you can put between is a USB unit or a plug module with more than one outlet. It's also fairly tricky to push the units together, and if you aren't quite strong enough you end up wondering why it's not working. Finally, it's bigger than you think, so you don't really save any space. I gave it away.More > < Less




It is a good product to have on hand, particularly when traveling and need additional outlets to charge your phones, and tablets.


Needs Improvement


Great idea, but they should all come apart, not just one.

This power strip adapts to you.


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.
