Choosing an automatic transfer switch for backup power usually starts with one question: how much of your home or shop needs to keep running when the grid drops? Do you need headroom for a whole-house draw, or just enough to keep a few critical circuits alive? The two switches here answer that differently. The Jaxvio unit targets a larger feed with more amperage headroom, while the smaller-capacity switch is built for lighter circuits and brings extra control options to the mix. Their listed prices sit only a few dollars apart, so the real decision comes down to how much load you need to cover, pole count, and how much control you want over the changeover.
Quick verdict
Pick the Jaxvio if you're switching a heavier feed and want maximum headroom on current. Choose the smaller-capacity unit if you want a roughly two-second changeover and the extra control options.
Side-by-side comparison
Here's the compact comparison of the two automatic transfer switches at their listed prices.
| Feature | Jaxvio 3-Pole 100A ATS | 2-Pole 63A ATS |
|---|---|---|
| Listed price | USD 23.99 | USD 27.99 |
| Price bar | ||
| Configuration | 3-pole | 2-pole |
| Rated amperage | 100A | 63A |
| Voltage | 110V control voltage | AC 110V line voltage |
| Operating modes | Automatic grid-to-generator switching | Automatic self-cast + manual |
Where each product wins
The Jaxvio wins on capacity and simplicity. Its higher rating and extra pole make it the heavier-duty pick, and it handles automatic switching between city grid and generator - a straightforward setup for a larger transfer point.
The smaller-capacity switch wins on control flexibility. Its self-cast mode works without intervention, it includes an indicator light display so you can see which supply is live at a glance, and the manual button adds a hands-on option when you'd rather decide yourself.
Product notes
NEW ATS PC Dual Power Automatic Power 3Pole 100A 110V Transfer Switch Grid
This Jaxvio model (W2R-ATS-3P-100A-110V) is the capacity-first choice. It's built to move a larger load between city grid and an AC generator, and it works as an automatic switch: when the normal supply fails, the standby supply takes over, and it selects whichever source is live. If your transfer point is a bigger panel, this unit is built to that spec. The trade-off is simplicity: this is the straightforward automatic option, without the added operator controls of the other unit. That makes it a clean fit for a simple auto-transfer job.
2P Dual Power Automatic Transfer Switch 60HZ Changeover Transfer Switch Tool 63A
This is the control-flexible option in the pair. Its conversion runs automatically, and it switches over in about two seconds - useful if you care about how quickly the changeover happens. The indicator light display shows supply status at a glance. It's sized for lighter loads: the line-current rating fits smaller circuits rather than a big main feed. The limitation is that ceiling - it won't handle the kind of load the higher-capacity Jaxvio is rated for. If your backup panel is lighter, this one earns a look.
Final choice by use case
For a larger transfer point where you want the higher-capacity option, the Jaxvio automatic transfer switch at USD 23.99 is the one to take. If your load is lighter and you're drawn to the control-oriented package, the smaller-capacity changeover switch at USD 27.99 is the fit. The $4.00 gap between the listed prices is small enough that the deciding factors should be the load you need to cover and how much control you want over the changeover.
