Review: Great Customer Service After Initial Issue - Update 02/06/25 - I contacted their customer service and they were extremely helpful in solving the issue by issuing a replacement. Replacement is working great. Initial Review - I purchased this transformer to power our Blink doorbell/door cam. It worked fine for the first 2 years, however right after we crossed the two year mark, we received a low battery message from our Blink doorbell. I thought that was strange because it was supposed to keep the doorbell/camera working without using batteries but figured maybe the batteries were low on their own. I swapped batteries but then received another low battery notification a couple weeks later. I went to our crawlspace where I had installed the converter and confirmed that there was still AC power to the unit. I then checked the output terminals and measured that there was no voltage (DC voltage) across the two terminals. Something failed on the internals of the transformer that means it is no longer outputting the required (or any) voltage. The unit is in the crawlspace and hasn't been touched since it was installed and working successfully. Disappointing to see it fail after only 2 years. With no moving parts and no physical impact/use, it feels like it should last much, much longer. Now we're left trying to figure out what to do to replace it after only two years. ## Features - 【16V 30VA Doorbell Transformer】Input: 120V, 60 HZ; Output: 16V at 30 VA; Load voltage: 16V ±5% No-load voltage: 19V ±5%; Low voltage hardwired doorbell power supply for residential, commercial and industrial use, offers reliable performance, safe to use - 【UL Listed】This doorbell transformer has passed the ul test, which greatly improves safety and longevity, as transformer without this certification have a higher risk of circuit induced fire house problems during operation(Note: slight operational sounds are normal and not a cause for concern.） - 【Compatibility】The transformer doorbell power supply compatible with Honeywell thermostat and doorbells, Nest, Ecobee, Sensi and Ring doorbell transformer - 【Easy to Install】The 16V doorbell transformer is easy to replace and install, and can be screwed, threaded, or threaded clamped to the electrical box, and we provide clear wiring diagrams for proper wiring - 【Professional Customer Service】Maxdot doorbell transformer focuses on high quality product and improving good customer service, if any doorbell transformer can't meet your expectation, please contact us and we will try our best to solve the problem; If the problem cannot be solved, you will be refunded or exchanged ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GND8RMQ | | Best Sellers Rank | #26,024 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #14 in Door Bell Transformers | | Brand | Maxdot | | Brand Name | Maxdot | | Current Rating | 1.5 Amps | | Customer Reviews | 4.5 out of 5 stars 8,608 Reviews | | Global Trade Identification Number | 00797153595131 | | Included Components | no | | Item Dimensions D x W x H | 2.6"D x 2.4"W x 3.9"H | | Item Type Name | Doorbell Transformer Compatible with Ring Video Doorbell Pro 16v 30va Hardwired Door Chime Transformer | | Item Weight | 1.7 Pounds | | Manufacturer | Maxdot | | Maximum Frequency | 60 Hz | | Minimum Frequency | 1 Hz | | Model | Maxdot T57-0052 | | Mounting Type | Wall Mount | | Part Number | T57-0052 | | Power Source | Corded Electric | | Product Dimensions | 2.6"D x 2.4"W x 3.9"H | | Specification Met | UL | | UPC | 797153595131 | ## Product Details - **Brand:** Maxdot - **Current Rating:** 1.5 Amps - **Mounting Type:** Wall Mount - **Power Source:** Corded Electric - **Product Dimensions:** 2.6"D x 2.4"W x 3.9"H ## Images ![Maxdot 1 Pack Doorbell Transformer 16V 30VA Compatible with Ring Wired Video Doorbell, Safe UL Listed Wired Door Bell 30VA Kit, Easy to Install Door Bell Transformer for Home - Image 1](https://m.media-amazon.com/images/I/71atZill11L.jpg) ![Maxdot 1 Pack Doorbell Transformer 16V 30VA Compatible with Ring Wired Video Doorbell, Safe UL Listed Wired Door Bell 30VA Kit, Easy to Install Door Bell Transformer for Home - Image 2](https://m.media-amazon.com/images/I/71Wp+HUwsoL.jpg) ![Maxdot 1 Pack Doorbell Transformer 16V 30VA Compatible with Ring Wired Video Doorbell, Safe UL Listed Wired Door Bell 30VA Kit, Easy to Install Door Bell Transformer for Home - Image 3](https://m.media-amazon.com/images/I/71BJwkz+P3L.jpg) ![Maxdot 1 Pack Doorbell Transformer 16V 30VA Compatible with Ring Wired Video Doorbell, Safe UL Listed Wired Door Bell 30VA Kit, Easy to Install Door Bell Transformer for Home - Image 4](https://m.media-amazon.com/images/I/61IgPZq8roL.jpg) ![Maxdot 1 Pack Doorbell Transformer 16V 30VA Compatible with Ring Wired Video Doorbell, Safe UL Listed Wired Door Bell 30VA Kit, Easy to Install Door Bell Transformer for Home - Image 5](https://m.media-amazon.com/images/I/611tgJy5u7L.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Questions & Answers **Q: Bought the 16v 30va transformer, now how do I find a 16v 30va doorbell? Electrician says anything smaller will be fried by the transformer.** A: Just buy a 16v doorbell. Amazon sells them. The 30va is amount of power it can deliver. Doorbell will only draw the power it needs. 30va can power multiple doorbells or just one. I got this 30va model to power existing doorbell and a Ring video doorbell unit. Get a new electrician. **Q: Is this fine for a standard door bell not a video bell?** A: It depends on your door bell, but most likely. Older doorbells require around 8 to 20 volts and newer doorbells require 8 to 24 volts. This 16V transformer is in the sweet spot where most doorbells would probably work. It swaps in easily if you are just removing an older broken transformer. **Q: What door chimes are compatible with this 16v 30va transformer and the Ring Pro doorbell?** A: all of them. **Q: My indoor mechanical Chime is says 10-16 volts ac. Will this transformer be too much power and safe to install?** A: very safe. i installed mine in 10 minutes with no problems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ worked to fix problems with door bell camera *by R***. on March 22, 2026* easy to install. the transformed upgrade from 5/10v helped to resolve the intermittent internet connection with an amcrest doorbell. ### ⭐⭐⭐⭐⭐ Great Customer Service After Initial Issue *by A***Y on January 28, 2025* Update 02/06/25 - I contacted their customer service and they were extremely helpful in solving the issue by issuing a replacement.

The chime only cost me like $20 at Lowes. The old chime, even before the Ring Doorbell Pro barely rang. The old transformer was 16v 15 amp. The new chime rang fine and the Health of the Doorbell was fine. However I wanted a better transformer to avoid issues. This new one is 16V 30 amp. I bought another one for my house to replace a little 10 A one. The old one used the metal box as the ground, this new one has a plastic nut to attach it and a separate ground wire. So I used a short green grounding wire from Home Depot (Lowes sells ones that have a poorly designed screw that does not cut into box hole) to screw it into a hole in the box, cut off the other end and stripped it and connected it to the green ground wire on the transformer. The new House Door bell chime much louder with this transformer and seemed to happen faster. The chime itself requires a 10 amp transformer, so I have plenty for the RIng Doorbell Pro and the Chime. The transformer was super well packed and looks like a quality product. I also like the way the transformer has a cover over the transformer plates shielding it. The price was great too! It is UL approved and well documented. It has a internal thermal fuse (115 degrees)on the low voltage end. At night and when someone rings the bell more power is needed and this transformer is just the thing you want to avoid issues. Be aware, the electrical box where you old transformer is could have more than one live circuit running in it, so shutting off the power to the doorbell may leave a hot line inside yet. So know what you are doing. One tip is that you should cut the insulation to about 3/4-1" on the three transformer wires BEFORE you install it to provide enough room to wrap it around the wires and not totally depend on the plastic wire nuts to hold it. And remember you are talking about 120 V circuit here, so know what you are doing and shut off all breakers for all lines in the box and test there is no power inside before starting. FYI I have a circuit breaker box tracer and wireless power tester to aid me. If you don't know what you are doing get someone who does. ## Frequently Bought Together - Maxdot 1 Pack Doorbell Transformer 16V 30VA Compatible with Ring Wired Video Doorbell, Safe UL Listed Wired Doorbell 30VA Kit, Easy to Install Door Bell Transformer for Home - Newhouse Hardware CHM1 Door Bell Chime, White - Ring Video Doorbell Wired (newest model), Use Two-Way Talk, advanced motion detection, HD camera and real-time alerts to monitor your front door (wiring required) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/81278692-maxdot-1-pack-doorbell-transformer-16v-30va-compatible-with-ring](https://www.desertcart.ph/products/81278692-maxdot-1-pack-doorbell-transformer-16v-30va-compatible-with-ring) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-19*
