Small USB-C accessory can turn any smartphone into a retro gaming handheld

Retro gaming handhelds have been making a huge comeback, capturing the nostalgia of pixelated adventures and the unmistakable feel of Game Boy days. There’s something magical about those vertical, pocketable consoles that modern giants like the Nintendo Switch and Steam Deck just can’t quite replicate. For anyone who loves the spirit of classic gaming, it’s hard not to get swept up in the excitement.

But if you already own a smartphone, you might wonder why you’d want to shell out for another device just to relive those memories. That’s where this clever little DIY USB-C accessory steps in. Just plug it into the bottom of your phone, and you’re suddenly holding a handheld console that channels all the best vibes of iconic retro machines—without breaking the bank.

Most gaming controllers for phones borrow from the horizontal layouts of PSPs and Switches, using clamps and grips that put controls on both sides. While that works great for today’s action-packed titles, classic games often don’t need all those extra buttons or fancy designs. The charm of this portrait-mode gamepad is in its simplicity and devotion to the original handheld experience.

What makes this accessory unique is its orientation. By plugging in at the bottom, it transforms your smartphone into a vertical gaming wonder, evoking the iconic silhouette of the Game Boy. Even though it’s compact, it packs plenty of buttons, including shoulder buttons on the sides for those who want a bit more control. It’s stripped down, yet surprisingly versatile.

Using USB-C offers some important advantages over Bluetooth. There’s no need to worry about syncing or interference, and you don’t have to charge the gamepad separately since it draws power right from your phone. No fiddly clamps or complicated attachments, just a snug fit and instant retro fun. The transparent shell even adds to the old-school appeal, letting you see the circuit magic at work.

Of course, there are some quirks to this design. The compact build can make things a little cramped, and the weight of the phone puts extra stress on the USB-C port, depending on how you hold it. Still, for DIY fans and retro gamers who crave a unique project, this portrait mode gamepad is a playful, affordable way to enjoy classic titles and show off your maker spirit.
