What customers say
Travelling with my PS5 and Switch 2
Received the monitor yesterday and as soon as I opened it, I could tell it was a premium product. The build quality is excellent and the screen is bright and clear. The included accessories are high quality and work well with the monitor. The monitor is a great size and is perfect for gaming while travelling with my PS5 and Switch 2.
No power required, straight 144hz output
Plugged it into my ROG Ally in it worked straight away! No power required, straight 144hz output onto a 16 inch screen. It's the perfect accessory for my Ally.
Works greats with my Steam Deck
It works great with my steam deck, and really makes a difference. The only downside is the cable is a bit short and the kickstand could be bigger, but that's not a deal breaker.

The Story Behind the Product
Built by someone who actually cared.
Why I built the Flow V1
I've been an avid PC gamer my whole life — and before that, I was addicted to the original PSP, Nintendo DS, and every PlayStation I could get my hands on. About a year ago I got into handheld gaming properly, tried a bunch of different devices, and my favourite ended up being the ASUS ROG Xbox Ally purely based on performance and ergonomics.
The specific moment that triggered the idea was playing Hades on it. While upgrading my stats between runs, I found it genuinely annoying to read the small screen — and after a few hours I started noticing neck and back pain too. That's when it clicked: the portability was there, the performance was there, but there was no display solution that felt purpose-built for this.
I had never really seen the two brought together properly, which is what sparked the Flow V1. My goal was to create a portable monitor specifically designed for handheld gaming — with the right specs, the right accessories, and an experience that feels effortless. It is the product I wish existed when I was looking for one myself.

Why I started TahTech
TahTech actually started long before the Flow V1 — cleaning, refurbishing, and reselling consoles and laptops on eBay. It was a good grounding in what people actually value in tech: reliability, presentation, something that feels cared for. But I always knew I wanted to build something of my own. A real brand, with a real product that had my name behind it.
The moment that made it click came one evening while I was gaming on my handheld. I wanted a bigger screen — something to properly sit back and play on — and I started searching. What I found was a mess of generic monitors with no real thought put into the handheld use case. Too heavy, wrong aspect ratio, mediocre refresh rates, or just cheaply presented with no soul to them. Nothing felt like it was actually made for this.
That was the gap. And I realised I was in a better position than most to fill it — I understood the market, I understood what good presentation looked like, and I knew what I'd want to own myself.
The Flow V1 is the result of that. A monitor built specifically for handheld gaming, with the specs, the bundle, and the attention to detail that the category was missing. TahTech is about making products with real purpose — for people who care about their setup and want something better than the standard option.
