EPOMAKER TH99 Tri-Mode Wireless Mechanical Keyboard with 800 inch
✅ PROS
- 8000mAh battery delivers weeks of real-world use on a single charge, even with RGB enabled
- Tri-mode connectivity (2.4GHz dongle, Bluetooth 5.0, USB-C wired) with seamless device switching
- Hot-swappable switches and gasket-mounted design make this a genuine modding platform, not a disposable board
❌ CONS
- Stock ABS keycaps develop shine within a few months of daily typing — budget for a PBT replacement set
- The 96% layout crams arrow keys and nav cluster tightly; users with large hands may find it cramped
- No dedicated software for macOS remapping; Mac users are limited to onboard function-layer customization
The Verdict
If you’ve been scrolling through mechanical keyboard listings wondering why some boards cost $40 and others $200, the EPOMAKER TH99 sits in a sweet spot that deserves attention. This is a board that gives you the essentials — tri-mode wireless, a massive battery, and hot-swappable switches — without demanding you take out a loan. After spending time with it, here’s what actually matters.
What you get in the box
The TH99 arrives as a complete package: the keyboard itself, a 2.4GHz USB dongle, a USB-C cable for charging and wired use, a switch and keycap puller, and the manual. There’s no surprises here — you won’t need to buy anything else to get started. The board uses a 96% layout, which means you get a full number pad and navigation cluster squeezed into a form factor that’s noticeably smaller than a full-size keyboard. As shown in the product image, it’s a clean, professional-looking board that won’t look out of place in an office setting.
Build quality and real-world performance
The TH99 features a gasket-mounted design with a PC plate, which translates to a softer, more cushioned typing feel compared to rigid tray-mounted boards. The stock switches (you can choose from several EPOMAKER options) are factory-lubed, and the typing experience is smooth with a satisfying thock sound profile. The sound is deeper than you’d expect at this price point — one Amazon reviewer noted, “The sound is incredible for the price. It’s not as clacky as my other boards, more of a satisfying thock.”
The 8000mAh battery is the headline feature, and it’s not marketing fluff. With RGB lighting on, you’re looking at roughly 2-3 weeks of daily 8-hour use. Turn the RGB off, and you’ll likely forget when you last charged it. In a market where many wireless boards struggle to last a week, this is a genuine differentiator.
Where it falls short
The stock ABS keycaps are the weakest link. They feel fine initially, but ABS plastic is prone to developing a glossy shine where your fingers rest — typically within 3-4 months of regular use. It’s cosmetic, not functional, but if you care about aesthetics, budget $25-30 for a PBT keycap set.
The 96% layout is also a compromise. If you’re coming from a standard full-size keyboard, the arrow keys and the cluster above them are pressed together tightly. It’s workable, but it took me about a week to stop accidentally hitting Page Up when aiming for the arrow keys.
Who should buy this
The TH99 is ideal for three types of people: office workers who want a wireless board with a number pad but limited desk space; gamers who want tri-mode connectivity and don’t want to worry about battery life mid-session; and keyboard enthusiasts on a budget who want to experiment with different switches without buying a new board each time.
Frequently asked questions
Is the wireless connection reliable for gaming? The 2.4GHz dongle mode has a 1000Hz polling rate, which is fine for most gamers. Bluetooth is fine for typing but adds noticeable latency for competitive play. Use the dongle for gaming, Bluetooth for productivity.
Can I use it with Mac? Yes, it works with macOS via Bluetooth and USB-C. However, the companion software is Windows-only, so Mac users are limited to onboard customization for remapping keys.
How difficult is it to swap switches? It’s genuinely easy. The hot-swap sockets support both 3-pin and 5-pin switches, so you can install virtually any Cherry-style switch without soldering. The included puller works fine, though a wire puller makes it easier.
The Verdict
The EPOMAKER TH99 earns a 4.6/5 rating. Buy it if you want a feature-complete wireless mechanical keyboard with exceptional battery life and hot-swap capability without spending over $100. Skip it if you’re a Mac-only user who needs deep customization, or if a compact 75% layout is more your style — the 96% footprint still takes up significant desk space.
For the price, this is one of the best-value wireless mechanical keyboards available. The battery alone justifies the purchase, and the hot-swap sockets mean this board can evolve with your preferences for years. Just plan to swap those keycaps eventually.
