I designed and developed two tech organizers for Db, targeted mainly at photographers but we all have tech stuff now a days that needs organising.

First out was the pro version, this was a padded and quite robust extra volume to sort your power banks, cables, hard drives and what not. It was modular which means you could use it as a organising pouch inside your bags, or if your needed extra space or quicker access to it you could mount it to the outside of your bag, slide it onto your hip belt or even attach it to your chest strap.

The second one was a slimmer more light weight version with the same organisational purpose. This one was also modular in it's own way where it fit into the grid of the camera cubes as well as inside the main compartments of the backpacks.
This one also comes with a removable SD-card pouch, which could either serve as an attached page inside the pouch or removed and zipped up for separate use or storage.
