Home Hub 4000 specs and battery

[cyberloard]

Hello, 

So I have just learned that the home hub 4000 has been out and about for the last while and I'm pondering on the upgrade depending on feature set.

Now I have been reading other forums such as DSL reports and the like to get information and specs on the unit, but as always its miss match of information. I did learn there is a single 10G Ethernet port for the LAN which is a very compelling reason to  upgrade the HH3000 and maybe the package. I also read we've ditched the SFP module which is meh to me. 

This leads to one feature that is getting covered and it's not even in the modem comparison for changing feature sets on Bell site for account changes and that is the backup battery. I've read a post or two that the Home Hub 4000 does not have a built in battery backup. Now that one is a bit of a deal breaker for me. I know I can just get a UPS for this function, but that is a extra cost to "re-add" a function the current or rather older generation already did.

If anyone has a Home Hub 4000 can you confirm if there is still a built in battery backup?

There is no need for Bridge mode. I plugged my router (Eero 6 pro) in mt hh 4000 and use that network at home. You can disable hh4000's wifi if you want.

Can someone at Bell answer this simple question ? How long will a ups last powering the hh4000 ONLY? Say for a 650 VA, 75 Ah UPS?

If you look at the power transformer for the HH4000 is should show you the VA of the power transformer. You can them divide the VA of the UPS with the VA of the power transformer and get the amount of hours.

It will be a long time, hours, if that is the only thing plugged into it. A good UPS will also have a display and software to show you the power consumption in real time, so you can monitor actual load. Just keep in mind that that does not equal internet access because the ISP equipment also needs power and will have a limit on how long it can stay working during a power outtage.

Thanks for the response!

Just a simple correction though. It's the VAh (volt-ampere*hour) of the UPS battery that counts. If the Hub consumes 70 VA of power, a 75 VAH battery of a 650 VA ups should last over an hour. (75VAh / 70 VA is a little more than 1h).

So, IF the 60 Watts rating of the Hub (roughly 70VA) is a maximum, then we need to know the "nominal" power of the Hub to make a good guess.

That is not the way it works because a battery stores energy. A 75VAH at 12V battery would store 900 Watt/hour. If you connect a 60 watts load to it, it would last several hours taking battery voltage drop into consideration.

That is why the output of the UPS is shown as 650VA, as it can output 650 Watts (roughly) for 1 hour. At 650 VA and 70 VA load, you would have several hours of uptime.

[SilverWerewolf]

I disagree: VA already is a measure of power. VA means Volts times AMPS. 

If the measure would be 7 Ah (7 amps-hours), then you could multiply it by 12 volts to get VAh (or watts hour, whatever)...

650 VA is just a measure of power, not energy. Running a 650 VA load for one hour is 650 VAh of energy.

The battery manufacturer clearly states 75 VAh of energy. So a load of 75 VA lasts only an hour.

Some high end Power Units like the EcoFlow River 2 claims it can support a WiFi modem for 23.7 hours at a 10watt draw. This means that nothing else can be connected to the Power Unit that can operate as a UPS with a 30 millisecond transfer.

[Watch me]

Is there a possible battery backup for the Giga hub with no interruption similar to the backup for the 3000 whose battery backup plugs right into the unit. I have a UPS but it does not switch over fast enough for the Giga hub.

Good Day.

There is no battery backup per se for the Bell Home Hub 4000 & Giga Hub that plugs directly in to the modem. The best you can do is purchase an uninterrupted power supply that you can plug your modem into when the power does go down.

APC, Tripp Lite, CyberPower are popular manufacturers. Depending on the demand placed on it, the UPS could provide power between 1-4 hours. You should be able to buy one for less than $200 + HST.

If you are looking for a UPS that maintains continuous power with no interruptions, you will need to shop for an online double conversion UPS that takes the incoming AC power supply and converts it to DC using a rectifier to feed the battery and the connected load via its built-in inverter. There is no switching of power when an outage occurs.

The companies that I mentioned earlier, also sell online UPS uninterrupted power supply units. Pricing for online continuous UPS power supply units start at a $1000 & go as high as $6,000. You can pick up a good quality unit for $1500 - 2,000 + HST.

Take care.
