Suitable UPS for ASUS RT-AC88U

[plato2322]

Does anyone use or know which UPS (Uninterruptible Power Supply) may be suitable for keeping an RT-AC88U going for 3-4 hours after a blackout? It's 19v and about 3.5a I think.

3.5 amps is what the supply is capable of at 19 volts DC. You need to look at what the input draw is at 110 volts AC or 240Vac if you're in Europe.

Either way, you may find it hard to find a cheap commercial grade UPS that will last 3 to 4 hours. What I did with mine, is removed the small battery and ran external leads to a much larger battery (20Ah).

Thanks, I'm in Australia so 240v AC. I know Telstra have a Smart 3Gen modem and sell a ups for $120 which they maintain will keep the modem/router going for 3-4 hrs so thought there may be a similar unit that would do my router.. I'm not overly technical so looking for a plug and play rather than get the soldering iron out.

Get a UPS with the biggest battery you want to pay for. Make sure it is user replaceable.
