Syntech Cross-Platform Gaming Sling Bag for Switch 2, Steam Deck & ROG Ally

Description

The Syntech Sling Bag for Switch 2, Steam Deck, ROG Ally is a larger carrying option for players who want enough room for a handheld console and the accessories that normally travel with it.

Instead of being molded around one specific device, the main console section is designed to work across several handheld systems. This makes it useful for Switch 2 owners who may also have a Steam Deck, ROG Ally, PlayStation Portal, or another similarly sized device.

The main compartment keeps the handheld in its own section while separate mesh pockets provide storage for larger accessories. Depending on the system you are carrying, these areas can be used for items such as a charger, dock, controller, cables, earbuds, or power bank.

A front compartment adds eight game-card slots along with extra room for smaller cables and accessories. There is also a rear pocket for personal items such as a phone or wallet, helping keep them separated from the gaming hardware.

For protection, Syntech uses a layered construction rather than a rigid EVA shell. The outer polyester material is designed to handle normal travel wear and light splashes, while an internal foam layer adds cushioning. The console area uses a softer lining to reduce rubbing against the screen and body of the handheld.

A side opening allows a charging cable to pass through the bag. You can keep a compatible power bank inside and connect it to your handheld without leaving the main zipper open. The opening itself does not provide power, so a cable and power bank are still required.

The adjustable crossbody strap can attach from either side, making it easier to choose which shoulder you prefer. Additional padding on the strap and back of the bag helps make a heavier gaming setup more comfortable to carry.

At roughly 13.8 x 7.9 x 5.3 inches, this is noticeably larger than a standard fitted Switch 2 case. The extra size is what allows it to hold larger accessories, but it also means this is better treated as a gaming sling or small tech bag rather than a minimalist console case.

📝 Koinlift Notes

This is another good option if you want something bigger than a normal Switch 2 case but do not necessarily want to carry a full backpack.

The three-compartment setup is probably the main reason I would choose this over a basic crossbody case. You can keep the handheld in one area, larger gaming accessories in another, and still have somewhere separate for things like your phone or wallet.

It also makes more sense if you own more than one handheld. A case made specifically for the Switch 2 may become useless if you decide to bring your Steam Deck or ROG Ally instead. With this, you can use the same bag and just change the setup inside.

The accessory space is useful if you normally bring a controller, charger, power bank, or smaller dock with you. I would still avoid assuming every large dock and full-size controller will fit together with every handheld. The more accessories you add, the more the available space becomes dependent on how everything is arranged.

The charging pass-through is also convenient, but I would not treat it like a built-in charging feature. It is really just a way to route a cable from a power bank stored inside the bag. You still need to supply the battery and cable yourself.

Compared with the COOWPS S3, this has a similar idea but goes about protection differently. The Syntech uses padded fabric layers rather than a hard EVA outer shell. That may make it feel more like an everyday sling bag, while someone who wants more rigid structure may prefer an EVA-style option.

I also like that Syntech is not designing this around one console generation. The company already makes accessories for Steam Deck, ROG Ally, Switch systems, and other handhelds, so this fits pretty naturally into its lineup.

The tradeoff is that this is fairly large for someone who only carries a Switch 2 and a few games. If that is your setup, an ultra-slim or mid-size case would probably be easier to carry.

Overall, I would look at this as a cross-platform gaming sling for a medium-to-large travel setup. It gives you considerably more room than a normal console case without going all the way up to a gaming backpack.
