Connection + Power

Parts covered: wireless radio + antenna, receiver / dongle, battery, charging circuit, USB-C + cable.

1. How a mouse connects

Every mouse connects one of four ways.

Wired cable, no battery

2.4GHz dongle, for gaming

Bluetooth no dongle, office

Tri-mode all 3 in one

• Wired: always connected, no power saving -> full speed. Cheaper (no battery, no wireless chip), never needs charging.
• 2.4GHz wireless: uses a dongle + a custom fast radio link. This is the GAMING mode.
• Bluetooth: no dongle, great for laptops + office - still too slow for competitive gaming.
• Tri-mode: wired + 2.4GHz + Bluetooth (or NearLink) in one mouse.

~ like: 2.4GHz = a private phone line to your PC. Bluetooth = a shared public line.

2. Same idea, different brand names

Every brand gives its 2.4GHz tech a fancy name. They all do the same job: a fast private link through a dongle.

LIGHTSPEED - Logitech

HyperSpeed - Razer

Quantum 2.0 - SteelSeries

SLIPSTREAM - Corsair

SnappyFire - Ninjutso x PixArt

Smart Speed X - budget (Beken CompX)

~ like: Maggi, Yippee, Top Ramen - different names, all instant noodles.

e.g. Razer also sells a 'HyperPolling' dongle for 8000Hz. Ninjutso Sora V3 includes its SnappyFire x PixArt 8K receiver in the box.

3. NEW: NearLink (SparkLink)

• What: a newer Chinese short-range wireless standard, showing up on some mice (e.g. tri-mode NearLink / 2.4G / Bluetooth models).
• History: the alliance behind it started on 22 September 2020 as the 'SparkLight Alliance', later renamed the NearLink Alliance. Early nickname: 'Greentooth'.
• Claims: low-energy mode for mice + headsets, on 2.4GHz, up to 12 Mbit/s (6x Bluetooth), 250 microsecond latency.

!! These are STANDARD claims, not test results. Test a NearLink mouse like any other before you trust the number.

~ like: a new highway built by a different company - promised faster, but check the real traffic yourself.

4. Wireless vs wired latency (honest truth)

Bluetooth bar is a rough visual, not an exact number

• Top wireless mice (e.g. Logitech Superlight) test around 1-2 ms click latency - same class as wired.
• Wired still wins on: price, no battery, plug-and-play, zero charging.

~ like: old phone calls had a delay; today's video calls feel instant.

5. The dongle (receiver)

• 1K dongle: normal receiver, up to 1000Hz.
• 4K / 8K dongle: special high-speed receiver. Sometimes in the box, sometimes sold separately.

e.g. WLMouse Beast X / Strider: 8000Hz wireless only with the included 8K adapter.

e.g. Some budget brands: 4000Hz only with an OPTIONAL 4K receiver - check the box before you buy!

Why dongle placement matters:

keep the dongle as close to the mouse as you can

e.g. 8BitDo Retro R8's charging dock doubles as a signal extension. Logitech gives an adapter to put the receiver near the pad.

6. Interference (crowded 2.4GHz)

• Wi-Fi router, Bluetooth, microwave, baby monitor, USB 3.0 port - your mouse signal has to get through all of this.
• Many devices share 2.4GHz. Modern gaming mice use frequency hopping = jump to a clearer channel automatically.

• USB 3.0 tip: USB 3.0 ports can create radio noise near 2.4GHz. Try the dongle in a USB 2.0 port or on an extender close to the mouse.

~ like: talking in a crowded wedding hall - move closer or find a quieter corner.

7. Battery

• mAh: milli-Amp-hours = how much energy the battery stores. Bigger = more hours, more grams.
• Li-ion / Li-Po: lithium-ion / lithium-polymer. Li-Po can be made in flat, custom shapes - handy inside thin, light mice.

e.g. WLMouse Beast X / Strider: 300mAh. Endgame Gear XM2we: 410mAh (~1 week). OP1we: 335mAh (~1 week).

e.g. Some brands say many sub-60g mice cut batteries to ~250-300mAh to save weight.

Battery life depends on polling rate:

rough idea, not exact - always test yourself

e.g. Logitech Superlight 2 DEX: up to 95 hours. Razer Basilisk V3 Pro: up to 90 hours. Budget 250mAh tri-mode: ~40h at 1000Hz.

e.g. Logitech G305: 250 hours on a replaceable battery.

• 'Up to X hours': ask at WHICH polling rate - brands usually quote the best case.
• Battery care: don't leave it at 0% for months; batteries slowly lose capacity with age + heat.

~ like: a phone battery - 2 years later it doesn't last like day 1.

8. Charging

• USB-C cable: most common. Check: can you play while charging? (port position + cable drag)
• Charging dock: place the mouse on a stand - some docks also act as a dongle extender.
• Charging circuit: small chips inside that charge the battery safely.

e.g. Razer Mouse Dock Pro + Wireless Charging Puck - both sold separately.

Logitech POWERPLAY 2 (charge while playing):

• No receiver inside: POWERPLAY 2 only supplies power - use your mouse's own dongle.

e.g. Works with Superlight 2, Superlight 2 DEX, Superlight, PRO 2 LIGHTSPEED, PRO Wireless, G703, G903, G502 X PLUS / LIGHTSPEED, G309 + more.

~ like: wireless charging for phones - but it keeps working while you're using it.

9. Cables (wired mice + charging cables)

Different cable types feel very different - a stiff cable pulls on your mouse like a leash.

cable cut open (cross-section)

• Rubber: basic stock cable. Stiff, drags on the desk - the old reason people hated wired mice.
• Braided / fabric: woven cover, tough - but some are thick + stiff.
• Paracord: PARAchute CORD style - braided nylon sheath, super light, flexible, low drag. Feels almost wireless.

e.g. some thicker Razer Basilisk-style braided cords.

e.g. Razer SpeedFlex, Glorious Ascended Cord, HyperX HyperFlex, Endgame Gear Flex Cord 5.0 / 6.0.

• Coiled: curly cable for looks, often with a detachable connector.
• Charging cables: many wireless mice charge with a STIFFER USB-C cable than premium wired paracord - so 'play while charging' can feel heavy.
• Strain relief: the part where the cable enters the mouse. An ANGLED one lifts the cable off the pad.

e.g. Attack Shark R2 Pro comes with a coiled cable. Glorious sells an Ascend paracord charging cable so you can play while charging. Endgame Gear OP1 has an angled stress relief.

~ like: walking a dog - a stiff leash pulls you back, a light loose leash you barely feel.

Mouse bungee (cable holder):

e.g. Razer Mouse Bungee V3 (spring arm, fits rubber / braided / paracord), Endgame Gear MB1, Pulsar Micro Bungee ES, Glorious bungee.

~ like: a clothesline holding the cable up so it never touches the floor.

10. Sleep mode (wireless power saving)

• Sleep / idle mode: wireless mice go to sleep after some time without movement to save battery.
• Wake-up: some mice need a click or a move to wake - a tiny delay can annoy you mid-game after a pause.
• Wired = no sleep: wired mice don't need power saving, so they're always fully awake.

e.g. Endgame Gear says its wired OP1 8k doesn't need power saving because the cable keeps it connected.

~ like: a phone screen turning off when you stop touching it.

-> before you buy, check if the sleep timer can be changed in the software.

11. Connection + Power Dictionary

• 2.4GHz: 2.4 gigahertz - the radio band gaming mice, Wi-Fi + Bluetooth all use.
• RF: Radio Frequency - wireless signals.
• Dongle / receiver: small USB piece that catches the mouse's signal.
• Polling rate: how many times per second the mouse reports (1000Hz = every 1ms).
• Latency: delay from your action to the result on screen.
• Frequency hopping: jumping between channels to avoid busy ones.
• Bluetooth: named after an old Danish king, Harald 'Bluetooth' - he united tribes, Bluetooth unites devices.
• BLE: Bluetooth Low Energy - the power-saving version.
• NearLink / SparkLink: newer Chinese wireless standard (early nickname 'Greentooth').
• Tri-mode: 3 connection modes in one mouse.
• mAh: milli-Amp-hour - battery capacity.
• Li-ion / Li-Po: lithium-ion / lithium-polymer batteries.
• USB 2.0 / 3.0: USB versions - 3.0 is faster but can add 2.4GHz noise near the dongle.
• USB-C: the reversible oval USB plug.
• POWERPLAY: Logitech's charge-while-you-play mousepad system.
• Paracord: short for PARAchute CORD - light braided nylon rope style, used for flexible mouse cables.
• Bungee: named after the stretchy bungee cord - holds your mouse cable up.
• Strain / stress relief: the flexible part where the cable meets the mouse, stops it breaking.
• Detachable cable: cable you can unplug + replace (USB-C on many mice).

12. What to test before you buy

1. Battery life at 1K, 4K + 8K - note start %, end %, hours.
2. Does 4K/8K need a special dongle? Is it included or an extra cost?
3. Dongle in USB 3.0 vs USB 2.0 / extender - any stutter?
4. Distance test: dongle at back of the PC vs next to the pad.
5. Bluetooth / NearLink: fine for office use? Note it's not for competitive play unless you test it yourself.
6. Charging: can you play while charging? Is there a dock? Any wireless charging support?
7. Charge time from 0-100% + any fast-charge claim.
8. Cable: rubber / braided / paracord? Stiff or floppy? Angled strain relief?
9. Sleep timer: how long before sleep, can you change it, any wake-up delay?

Remember!!

Gaming = 2.4GHz dongle (LIGHTSPEED, HyperSpeed... same idea). Bluetooth = office. Wired = no battery.

Modern wireless ~= wired latency. Keep the dongle close, avoid USB 3.0 noise.

Battery = trade-off hours vs grams. Higher polling = faster drain. 'Up to X hours' - at what Hz?

Cables: paracord > braided > rubber for low drag. A bungee lifts the cable off the pad.

NearLink = new standard with big claims - test it yourself.
