DIY Mini UPS for WiFi Router V5.0 || Multiple Outputs 12V / 9V / 5V

[@ishwardursen2864]

I am now 79 year old.I made this project 2 years ago and it is working excellently.We, here in South Africa , experience regular power outages and this project has been most useful.Many thanks and God bless you.

Is it work good mine is not giving good backup it only work for 20mins do you know what while be the problem

[@kevinjaspan9654]

I hear you and feel your pain. I was born in South Africa, though I left 37 years ago, and watch the shocking news continuously. Good luck with the Escom rebuilding or replacement! How can you live without reliable power is beyond me.

[@SazzadHossain-ww3xo]

Hi, thanks for sharing a nice & useful project with us. But I think in your design two thing u don’t design it carefully 1. 12v Output whens the the mains powers is active: u set input voltage 13 volt and its directly connected to output by a diode. If the foreword voltage drop is .3v the output voltage will be 12.7 v which is high for the 12v output. 2. power switching : whens the mains on 12v output jack provide 12.7 . Now power goes and battery pack start as u set buck boost converter output 12 v. Thats mean when power switches there always a 0.7v voltage spike it’s not god for router. Suggestion: 1. u can connect input 13v main power supply in input of buck boost converter not to output thus u get always a steady output voltage . 2. U can use electrolytic capacitor in input & output dc port to reduce ripple and get steady voltage.

[@opengreenenergy]

Thank you for the most valuable feedback. I was also thought to connect the adapter output at the input of the buck boost converter but changed my mind for considering the continuous power wastage in the converter module. But I missed the point that I am not using a 12V adapter at the input. Use of capacitor is nice feedback. I will update all these in my schematic soon.

Hi, i did this project using 2200uf/16V capacitor at the output terminal. But during AC to Battery switching output voltage is increasing to ~17V and decreasing to 12V. What might be the cause?

Seeing you plug it in I think the box could use some additional support designed in around those areas. Otherwise this was a quite interesting design concept. You could also add a USB plug using the 5v dc for charging phones while the powers out too.

These days all the routers have USB ports to charge phones you can connect to router.

Thanks for a great video.. This helped me a lot to make one myself. MOSFET idea was great for switching.. I had an issue to find the correct case since 3d printing is costly but found a plastic junction box from electric shop. Soldering worked for spot welder and MOSFET heating was an issue which was mainly due to oversite on diode usage which looped the power back from battery to gate. Thanks again.. Keep up your great work Sir

Remember! Most of the gadgets are working on just 12 volts DC power supply, and laptops are working on 20 volts DC power supply, so no need of buying big bulky and expensive inverters. After all every day, science and technology is getting advanced very fast. I've done this same project for my home use, it's very important, no need of big bulky and expensive inverter. Just a 12 volts battery and a charger and voltmeter.

[@Mechmantraprojects]

Hi admin, Can you make our existing circuit with solar power with normal electricity charger also. Case1 : when sun is there powerbank will run on solar pannel Case 2 : when sun is not there or low solar power it will shift to 12volt adapter power Case 3 : when solar and adapter power is absent it will shift to charged batteries. Everything should be automatic.

i have done experiments with Nokia G-140W regarding its supply voltage reliable operations. the router works fine with supply voltage from as low as 6v to 15v i didnt try supply over 15v as i was afraid of damaging the router. most router with 12 v input will run perfectly fine with output from 3s bms which outputs 9-12.6 volts.

[@HaiTHaMKoBeIssI]

very nice, just print PCB standoff for the converts in the box,

[@ronaksoni2729]

One flow is you have bypassed the 12-15volt input to output in mains mode when power is present and if the input is really 15volt this is going straight to the output and if modem is not tolerate to 15volt it can harm or burn the modem. I think this is serious problem.

A couple of things based upon my experience of building this router, first and foremost i am hobbyist it was super easy to follow your instructions and build it. 1. Around mosfet would be great if you can showcase which point gets to connected to where itll be easier i got stuck there and it took a lot of time. 2. Around input power i tried using the default adaptor of my wifi but thats only 12v and its unable to charge batteries beyond 11.4v and its heating a lot. 3. If ill use a 14v supply for input wouldnt it fry my wifi as the power from supply will be connected directly to output

Where you plug mosfet?

Bro did you get any trick to charge battery beyond 11.5v even I am also face the same problem 😢

[@davidecharm]

Hi. What is the power supply voltage for input? I read 12V-15V, but working with a 12V? The BMS need 12.6V. Thanks for your support!

[@kenanelicanov2327]

It is also interesting forme. I think the converter at input will be boos converter to boost 12v to 12.6 v from router adaptor

[@Ultimateharen]

​@@kenanelicanov2327battery will take too much time to charge too inefficient. Battery will get damaged after few months. Instead of that use 13v or 14v 15v adapter.

[@electronicslab_in]

1:39 mosfet used is P type as it connected on high side. It seems correct. But R2 is connected to groud. Shouldn't it be connected to positive of battery? So that gate of mosfet is pulled high when battery is not suppose to supply power and hence the mosfet to be remain off. When main adopter power cuts, gate should be pulled low (so in a way it is correct to connect gate to positive line of input buck converter but it should be connected through some resistor or a combination of BJT and resistor). Now another problem i feel is that when the battery is significantly discharged and main power gets on, circuit may not work as desired. Just were my thoughts. Any expert comments?

[@electronicslab_in]

Another way could hv been using a N channel mosfet but connecting in negative rail (but at same position) and controlling the gate using positive bus of input supply.

[@pawanprajapati3587]

Same problem after mains on curcuit is not working as previously. Any solution?

[@pradipkhangembam4294]

Hi I am replying to an old comment but I would like to know why do you think the circuit may not work as desired when the battery is significantly discharged? I may have come across this issue. Does it have to do with R2 connecting to ground?

[@davestech6357]

Mosfet not needed buck/boost converter not needed. 12.6 volt to battery parallel to output of 12 volt. 12 volt stuff should work to the cutoff battery voltage. Buck converter for lower than the 12 output. Only one diode needed for input charge of battery.

This has been one of the few DIY battery projects I have watched all the way to the end...Many of them I stopped watching after just a couple of minutes as the DIY'er was incredibly cavalier about how dangerous soldering directly to the LI-Ion batteries is...I enjoyed this one immensely and hope to dig into this as a future project...I did have one comment and one nitpick however: Was there a reason why you did not use proper connectors for the switches, fuses and other devices...Solder alone is not always the best solution...The nitpick: The voltmeter that you are using is quite thick (unsurprisingly) and yet you pushed it only barely through the box...Could you have printed the box with wider coller around where the voltmeter goes so it could be pushed flush against the inside as well as the outside?

Hi, Friend, this is an excellent video. I made the circuit and it is working fine. But I have an issue. When the main power is off, battery kicks in starts, and works properly. But when the power cut is longer and the battery power is not enough, BMS cut off the output to prevent over-discharging. And when the power comes back, I have to unplug the router and let the ups to charge about 3 hours before reconnecting. It seems 12v power supply is not enough to power the router and charge the dead battery pack at once. Can you find a solution to this problem?
