DieselnDust Posted July 24, 2023 Share So is that 1.5A input measured as constant load or max load? if constant load then the current draw from the AC output can be calculated. The input voltage is quite a wide range so what does it actually use? 100V or less? to use the power station the buyer needs a unit with an AC output. What is the max watts delivered from that output? Link to comment Share on other sites More sharing options...
madmarc Posted July 24, 2023 Share 31 minutes ago, mecheng89 said: Thanks. The reviews are a bit of a turn-off. These do work well, However - They are 7AH Lead Acid batteries - The Kickr pulls 5 amps so you will get just over 1 hour (7/5 =1.4 hrs) before the UPS shuts down. they get a bad rap because people draw them down completely and the battery deteriorates very quickly, common with lead acid. they are not designed for this and only really meant as an emergency back up in the event of power failure to give you time to save and shutdown PC's etc. I was about to bin mine and decided to open it up - I changed the battery to a 12v 7aH LI battery (not sure if it can handle this battery but did it anyway) it now lasts a lot longer - haven't tried it on the Kickr again but run 2 laptops and an external screen which lasts about 1:15 hr and the battery is still running strong after 3 months. Oh & BTW - i disconnect this thing from the mains when i'm not using it - It gets fairly hot and LI catching on fire is not uncommon - so be careful if you make this modification mecheng89 1 Link to comment Share on other sites More sharing options...
madmarc Posted July 24, 2023 Share 1 hour ago, mecheng89 said: The KICKR, according to their website, required 5A @ 120V AC. Little Gizzu is therefore underpowered.

But, what do I know. Thats wrong if you look on the power box Input is 100-240 V 1.7amps - AC output is 12v 5 amp DC The Gizzu 8800 mAh = 8.8 amp hr's should last 1hr45min if you run it on the 12v 3 amp output Link to comment Share on other sites More sharing options...

I got an ultralan 17.8 Ah off Takealot have used it for a 1hr45 session and it was on 50% when i finished Link to comment Share on other sites More sharing options...
Steady Spin Posted July 24, 2023 Share Be careful of the term UPS. They are generally a very short term solution that allows you to safely shut down your computer and electronics. Running items off these will destroy the batteries quite quickly. You need an inverter with a battery backup. DieselnDust 1 Link to comment Share on other sites More sharing options...
ChrisF Posted July 24, 2023 Share 5 hours ago, mecheng89 said: Good morning, techy Hubbers! Has anyone ever thought of using one of these "portable power stations" to power their smart trainer during load shedding? I must say, they look like an attractive solution, but man they are pricey. The Wahoo devise uses the least power of your trainer setup. You PC will be using a lot more power. The FAN more than doubled the power draw of all the other parts of my trainer !!! Even with ALL of this on, including the fan, my trainer uses about 300W. The typical 12V battery box system did this duty for many years. Link to comment Share on other sites More sharing options...

I only used it a couple of times for about a hour and it seemed to work fine, was only a temporary solution till I got an inverter. It didn't drain the battery past 75%. I did google quite a bit at the time if it would work, and while the kicker states 60w its actually less: ChrisF 1 Link to comment Share on other sites More sharing options...
Mongoose! Posted July 24, 2023 Share Let's hope the next generation smart trainers will supply power and not consume it. 🤓 Link to comment Share on other sites More sharing options...
dirtypot Posted July 24, 2023 Share I powered my trainer and a monitor for over three hours with a little router buddy box. The trainer hardly draws anything and works 100%. But that was using a laptop on its own battery and I moved my whole setup outside in the wind. Its a different story for powering a PC, TV and fan. But since then I've upgraded to a Neo2T and now don't need any power DieselnDust and ChrisF 2 Link to comment Share on other sites More sharing options...

The classic old UPS had weeks to recharge the battery, and it was to used for a safe shut down only. The current use of an "inverter" is similar in that should switch seamlesly between eskom and battery supply. BUT ... we now expect the battery to deliver full power for up to 4 hours, AND, we expect the system to recharge that battery in 4 to 6 houts for the next loadshed. The "old school UPS" units dont stand up to this level of abuse. But yes, both keep your equipment going when the power goes off. dasilvarsa 1 Link to comment Share on other sites More sharing options...
