Ring Pro Power Kit: What It Is and Which One You Need
The Ring Pro Power Kit is a small device that makes sure enough power reaches a hardwired Ring Pro Power Kit doorbell for it to work. Pick the version carefully. V2 supports chime bypass, while V3 ships with the Doorbell Pro 2 and has no bypass. propertystream
That one sentence prevents most wrong purchases. The rest of this guide covers why the versions differ, how to check your own setup, how to install the kit safely, and what to do when the chime misbehaves.
What the Ring Pro Power Kit Does
A hardwired Ring Pro Power Kit doorbell draws power from your existing low-voltage doorbell transformer. The Ring Pro Power Kit sits in that circuit and conditions the supply so the doorbell receives steady power instead of a weak or uneven feed.
Ring Pro Power Kit community guidance is blunt about it: a Ring Pro Power Kit is required for all Doorbell Ring Pro Power Kit installs. Skip it and you may see random reboots, a buzzing chime, or a doorbell that never fully wakes up. ring
The kit has two jobs, depending on version:
- Regulating power from the transformer to the doorbell
- Bypassing the indoor chime (V2 and the original cable) so the chime box doesn’t choke the circuit
Who Needs It and When
You need this kit if you own a hardwired Ring Video Doorbell Pro or Pro 2 and connect it to a doorbell transformer. Typical situations:
- New installation: the Ring Pro Power Kit comes in the box, so keep it with your install parts.
- Lost or damaged Ring Pro Power Kit: this often happens when someone removes an in-wall chime and the original part gets broken.
- Replacing an older doorbell: an old mechanical bell setup may need the Ring Pro Power Kit to power a Ring Pro Power Kit doorbell correctly.
- Bulk or professional work: installers, electricians, and property managers buy spare kits in 2-packs or via distributor part numbers.
Some Ring Pro Power Kit help pages now refer to the Pro-line product as the Ring Wired Doorbell Plus. Same family, newer name, so search both terms when you’re looking for support pages.
Version History: Cable, V2, and V3
| Version | Typical doorbell | Chime bypass | Key feature |
|---|---|---|---|
| Ring Pro Power Kit Cable (original) | Early Doorbell Pro | Yes | Used to bypass an internal doorbell |
| Ring Pro Power Kit V2 | Doorbell Pro | Yes | Resettable fuse; switch power off and on after a trip |
| Ring Pro Power Kit V3 | Doorbell Pro 2 | No | Ships with Pro 2; one buyer who expected V2 got a V3 with no bypass The difference between the Pro Power Cable and Ring Pro Power Kit v2 (for Ring Video Doorbell Pro) +2 |
The resettable fuse is the practical upgrade from the original cable. After a power trip or fault, you restore power at the source instead of replacing a part.
How to Tell Which Version You Have
Check the packaging and the model on the doorbell first. Then look at the kit itself:
- V2: has “Bypass Mode” holes for the doorbell wires and a rear lever that opens the terminal clamps
- V3: no bypass mode, usually supplied with the Ring Pro Power Kit 2
- Listings: compare the manufacturer part number. Ring’s Pro 2 kit appears under B089QXNLPV0 (distributor code 7G-SEKKD8000) with UPC 842861103250. adiglobaldistributionadiglobaldistribution
If you can’t confirm the version from the part itself, photograph it and ask Ring Pro Power Kit Support before ordering a replacement.
Compatibility: Voltage, Transformer, and Chime
A distributor listing states that the kit works with doorbell systems supplying 16–24 volts AC at 50 or 60Hz, up to 40 VA. The AC connector is described as a Class 2 energy source, meaning a limited-power supply category. avlgearadiglobaldistribution
Before buying anything, work through this checklist:
- Identify your doorbell: Pro, Pro 2, or Wired Doorbell Plus.
- Measure the transformer output with a multimeter. Switch the meter to AC volts and confirm you’re in the 16–24V range.
- Note your chime type: mechanical or digital.
- Decide whether you want to bypass the indoor chime.
- Check Ring’s compatibility tool for your transformer and chime.
Don’t treat step 5 as final. One user checked compatibility before buying the Ring and found their transformer listed as compatible, yet it still failed. A multimeter reading and a real test beat a database entry. ring
V2 on a Pro 2? Official Guidance vs Reported Results
This is the most debated question around the kit, and most guides skip it.
Ring’s official position: A Ring community moderator said the V2 kit isn’t designed for use with the Doorbell Pro 2. The same thread explains that for chime bypass with the Pro 2, you don’t need to install the V3 kit and should choose “I don’t need it” in the Ring app. ringring
What some owners report: One Pro 2 user found that V3 stopped the constant chime buzz but didn’t let enough power through to ring the chime, and a V2 replacement fixed it. Another confirmed V3 didn’t work with their mechanical doorbell, while V2 did. ringring
These are individual user reports, not endorsements, and results depend on your transformer and chime. If a Pro 2 chime won’t ring, work through this order:
- Confirm transformer voltage and condition
- Re-check the V3 wiring and the app’s power-kit setting
- Try bypass setup as Ring describes it
- Contact Ring Support before swapping to V2
How to Install the Pro Power Kit V2 (Chime Bypass)
Ring’s V2 bypass method is short, but treat the safety step as non-negotiable.
- Turn power off at the source. Use the breaker or transformer switch, not just the doorbell button.
- Remove the cover from your indoor chime unit.
- Insert the doorbell wires firmly into the Bypass Mode holes on the kit until they lock into place. ring
- Replace the chime cover.
- Restore power at the source.
- Finish setup in the Ring app by selecting your doorbell.
If you need to remove the wires, press the rear lever to open the clamps and pull the wires straight out. ring
For a V3 kit on a Pro 2, follow the instructions in the box and the Ring app prompts. The kit’s steps differ, and the app asks whether you installed it.
Tools to have ready: screwdriver, wire nuts, wire extenders (many Ring spare-parts kits include these, along with mounting screws, anchors, and security screws), and a multimeter. adiglobaldistribution
Warning: If you’re unsure about doorbell wiring, hire a licensed electrician. Low-voltage doesn’t mean zero risk, especially if the transformer is wired into mains.
Troubleshooting: Buzzing, Silent Chime, and Reboots
| Symptom | Likely cause | What to try |
|---|---|---|
| Constant chime buzz | Weak current leaking through the chime circuit | Confirm the kit is installed and the right version |
| Chime silent when pressed | Kit passes too little power to ring the chime | Check voltage, bypass setup, then contact Ring Support |
| Doorbell reboots repeatedly | Low or unstable supply | Measure transformer output under load |
| Power trips and won’t return | Fuse or fault condition | Cycle power at source (V2’s resettable fuse helps) |
What It Costs and Where to Buy
Prices vary widely by country, seller, and version. These are examples seen in recent marketplace and reseller listings (October 2026); check current prices before you buy.
| Listing type | Example price | Notes |
|---|---|---|
| eBay V2 2-pack | US $12.95 per 2 units | Listed for Pro and Pro 2 wired models |
| eBay V3 2-pack | US $11.95 per 2 units | Listed as Pro / Pro 2 |
| eBay single V3 | US $49.99, out of stock | Listing shows 1-month warranty |
| Reseller Pro 2 kit | $35.50 | Branded as Ring Wired Pro Power Kit Ring Pro Power Kit V2 (2 units) +4 |
If you’re working to a fixed budget, say around 1,300 in your local currency, add up the full job. The kit is often the cheapest part. A failing transformer or an incompatible chime can cost more than the kit itself.
How to Spot a Bad Listing
Marketplace specs can be sloppy. One V2 listing shows a 5V rating and a “Battery” feature, while a V3 listing shows 3V. Those values don’t match the 16–24V AC range above, so treat item-specifics tables as unreliable.
Safer habits:
- Match the manufacturer part number, not just the title
- Prefer Ring direct, known retailers, or distributors
- Check return policy and warranty
- Avoid listings that mix V2 and V3 wording (“both are common”)
Where to Buy by Region
- US and Canada: Ring’s accessories page, big-box retailers, distributors, and marketplaces. Low-voltage 16–24V transformers are common in homes there.
- UK: Ring’s UK support page shows a wiring example connecting a Ring doorbell directly to a UK transformer using the V2 kit. Follow your region’s guide, as transformer norms differ. ring
- Australia and Europe: Ring publishes regional help pages (for example AU and FR), so use the one that matches where you live.
- Professionals: installers and property managers can source through distributors using the part numbers above.
Pros and Cons of the Pro Power Kit
