MinimizeThe Aer Split Kit has a really minimalist footprint, especially when compared to the Aer Slim Pouch. It can only hold about 0.4L, so it’s going to be the smallest tech bag on this list.
Don’t let the size stop you, though. It’s expandable when you zipper the bottom and makes a nice sized compartment for your smaller items, like a mouse, small notebook or your charging cables.

4.34 / 5
The Aer Split Kit is an ultra-compact 0.4L tech organizer with an expandable design that packs slimly into backpacks or daypacks, while providing essential organization for minimalist travelers, commuters and every day carry.
Why the compact size works
- Ultra-minimal footprint: At 0.4L, it takes up virtually no space in your bag while still providing essential organization.
- Expandable design: The bottom zipper allows you to expand the storage when needed, giving you flexibility for different packing scenarios.
- Perfect for essentials: Ideal for carrying the most critical items you need on a daily basis.

What fits inside
You still have the side (or top?) compartment that’s always going to be great for pens or something low profile. The expandable main compartment works well for a mouse, small notebook, or charging cables when you need them.
The design is clever. It keeps your most essential items easily accessible while maintaining a minimal profile when you don’t need the extra space.
Build quality
Like other Aer products, the Split Kit is made from high-quality materials that ensure durability. The construction feels solid and well-thought-out, even in this compact form factor.

Versatility across devices
82%
Works well for essential tech items across different use cases. The expandable design adds flexibility, but the 0.4L capacity limits it to minimal setups. I'm never able to put something bulky, pointed or round in there, so I keep my items inside to those that are flatter.
