500 Rupees Inverter For Router ~ 24 Hours Backup

You can buy the circuit here: amzn.to/3BpWHI8
Power banks we used:
10000 mAH: amzn.to/3bHqqSF
20000 mAH: amzn.to/3vZoHkS
This project is about making a 24 hour power backup for wireless router. It works with all routers that consume up-to 2 Amperes of DC and require 6 Volts, 9 Volts or 12 Volts to operate. It works in inverter mode, meaning the router will power cycle when there is a power cut.
The power banks that we used support pass-through charging and do not switch when the power is restored, they only switch when the power goes off, this cuts down the downtime. Since it stays backed up for the whole 24 hours, we switch the wall power in the morning, run the whole day on inverted mode and switch it on in the night for the power bank to recharge. The router stays on when the power bank is recharging.
Compared to conventional router UPS that run for only 4 to 6 hours, this solution offers 4 times as much backup. The wireless router can be configured as a repeater and become made portable this way. We can move it closer to the computer, tablet or phone that we are working on to maximize available bandwidth.

What a DIY! You seems to have good understanding of electronics and technology in such young age. Awesome stuff keep exploring! 👍

[@ArjunAndVishnu]

Sir, thanks a ton 😊 I've been exploring electronics for long. I had toys like Snap Circuits (and others that are similar), which helped me understand things.

[@crazydrifter13]

I also thought of powering the router with a power bank but then I discovered my ISP's power also cuts off when the power goes out.. no power backup there😂

[@srinivaspiratla2272]

Awesome explanation. Keep doing..

[@ArjunAndVishnu]

Thank you Sir

[@MaheshBhupathiparthasarathy]

Excellent Idea

[@ArjunAndVishnu]

Thank you for the appreciation Sir 👍

Great video, congratulations 🎉
I'm using MI 3c router for which the adapter output is 5v 1a so I connected directly to 10k power bank and it worked but there was some noise coming inside the router and I disconnected it.
Ive ordered for the step up module so what voltage shd I adjust to 6v or 12v

[@ArjunAndVishnu]

Thank you! The voltage you should use is printed on the adapter. You need to use the exact voltage for proper functioning.
Mi 4C needs 12v @ 500mA, Mi 4A needs 12v @ 1A.
I do not have info about the Mi 3C. If it is 5V @ 1A, you might not need the circuit at all. The hum you hear from the router is probably because of the insufficient power, and the capacitors working hard. Try using a different powerbank, or a thicker cable.

Where i can buy it you’re link is not opening

[@shailendrakashyap8577]

I try on my jio fiber but not working, 2.5 amp is written there
How i get 2.5 amp

[@ArjunAndVishnu]

The circuit can handle a maximum of 2 Amps with heatsink and 1 Amp without heatsink.
Also, powerbanks usually have a peak output of 2.4 Amps. So, Jio router exceeds the amperage of this setup.

[@shailendrakashyap8577]

Then why my not working.i do same as u say 🙁

[@ArjunAndVishnu]

Your Jio Router needs 2.5 Amp, as you said. This circuit cannot deliver above 2 Amps, so it will not work.

[@shailendrakashyap8577]

@@ArjunAndVishnu any other way please tell if possible

[@ArjunAndVishnu]

Here's the logic: Even of you buy/make a circuit that can deliver 2.5 Amps, the limiting factor is that powerbanks can still output 2.4 Amps only (at 5V).
Generally speaking, routers do not consume peak power all the time, so it might work with a 2.4 Amp powerbank. However, when the router is at peak load, the powerbank may just shutoff due to overload protection. So, this is not a practical solution for such loads.

[@bumblebeeytgaming8694]

I am not able buy it

[@ArjunAndVishnu]

Looks like it is out of stock. I found a similar one, however, it is pricey: amzn.to/46HoxAi

[@rejiscaria6862]

Tell me ampere

[@ArjunAndVishnu]

Circuit can handle a maximum of 2 Amps with heatsink and 1 Amp without heatsink. Check the power requirements of you router and decide if you need a heatsink or not.

@@ArjunAndVishnu i need 5 volt for media converter and 9 volt for router.....is there any idea?

[@ArjunAndVishnu]

Powerbanks usually have 2 output ports. You can use one 5v output directly for the media convertor. You boost the other output to 9v using the circuit and use it for the router. What you need to factor in is the total output amperage. Check the maximum output current of your powerbank, it is usually 2.4 amps for all ports combined; do not exceed that. Use a 5 volt 3.5 amp wall adapter to charge the powerbank; so that there is the additional headroom to use the connected devices simultaneously while charging the powerbank itself.
