PHS300 A/C -> battery handoff...

Does anyone know how the PHS300 handles switching to and from A/C and battery mode?

I want to know if it will stay connected even when switching from one source to the other. I want to use it in my car and the power gets cut on my CTR350 when I start my engine.

Thanks! Very Happy

when i pull the a/c adapter from an operating phs300, it automatically switches to battery power, without losing connection.

just like you hope it would!

That's great news!

I kinda figured it would work like that, but it's best to get confirmation.

And...

While plugged in via AC, you can swap batteries without losing a connection.

Very nice! The PHS300 is going to be a very cool product. I'm wanting to purchase one, but I hesitate over losing the ethernet jack, which is so useful for sharing a hotel network easily among many family devices when wifi isn't present.

The sustained power when switching your vehicle on/off may be worth the upgrade though, although my Durango's rear power source isn't switched, so I don't have to worry about it there, (just have to remember to unplug it when not travelling).

Our other vehicle would see the benefit, however. I prefer to mount the router in the rear of the vehicle, so it's out of sight and out of the way. With the PHS300, if you have a switched power source, you wouldn't necessarily have to worry about unplugging a CTR-350, but if you wanted sustained service whether the vehicle was on or off, you'd need a PHS300 - then you have to either leave it and let the battery drain, to recharge when you next drive, or have to turn it off.

There are benefits to both. I forget how Lithium ions handle repeated full discharges, I wonder if that would be a problem.

It may also be possible to use a battery backup like an APC with surge protection and battery power. Plug it into your ac outlet or an inverter and then plug your router into the ac outlets on the ups that deliver battery backup power.

If this works, the batteries in even the smallest APC ups should power the router for a week or two.
