I think this is a very simple yet effective design, very different from the others. Great job Sorin! It shows that you research the subject and come up with better solutions.

[@CCG0D]

This will be perfect for dashcam to record while car is off. I rewatched the video and found everything were there including which way to assemble each component as well as the value of each component. Very useful with the links to buy them as well. Great video Sorin!

[@cristian.duluman]

I need this!! Thank you, Sorin!!!! As usual you bring good content. God bless you!! 😊

[@VerifyIT]

I really appreciate that you started to have links for the components you are using. As always, very instructive project

[@red.kardinal]

May I suggest putting a Schottky diode in series with the battery as it has about 0,3V drop.. As long as it can handle the 2A max current

[@mr.makeit4037]

Just ordered a multipack of those tp5100 modules to try out. I'm still a fan of the tp4056 and have many. But the increased voltage input on the tp5100 is intriguing. Good job. Thanks for the info Sorin.

[@Raress96]

Really nice, been wanting to build a UPS for quite some time now and this will definitely help!

[@rhiantaylor3446]

Neat, in fact very neat ! Worth mentioning that you chose a TP4056 board that includes the DW01 FETs discharge cutoff to avoid over-discharging the cells.

[@DanielLopez-kt1xt]

It's allways good to see new DIY designs... i used the TP4056 a lot in the past, but now i changed to the TP5100... also accepts 5v, up to 18v, and it's a buck charger, so it will be much more efficient, so less power wasted into heat...

[@sajidmohammad3190]

Yes TP5100 is lot better than TP4056

[@nosafetyswitch9378]

I am having the same issue with my DIY Bluetooth speaker when trying to turn it on, i have a toggle switch too and the only way to turn it on is to flip the switch on an off a few times quickly. I have added among other things a boost converter for the amplifier and the capacitors are not kind to the battery during startup. It works fine when it is connected to USB power though, exactly the same issue like yours!

Thank you for designing this :)

[@VrumsAdventures]

Small hack I use for a similar application (actually I only want to be able to power my circuit from the same USB as the battery is charging while the battery is charging, but the trick applies here I believe): you can set the charge current for your battery pack from TP4056 by changing the resistor on it and you can select the maximum charging voltage by putting a diode in series with the battery and choosing the diode which has a small difference of the forward voltage at the max charge current and at zero charge current so that the battery doesn't go into a start-stop charging loop. I use a 1N4148 and set the current at 300mA... it charges the battery at ~3.8V and I don't see the blue and red LEDs flicker when charging ends. I used this trick to make my nephew a music box with a DFPlayer mini and it's on the original Li-ion batery (1 cell) for 3 years now, being played every day and charged every other day. It's a miracle I can still think without singing "Aramsamsam" or "Lulu danseaza-n poienita" constantly :D

You can cut the charging of the batteries by adding a LM431 adjustable zener shunt regulator connected to another relay/mosfet or just use a different Rprog resistor to lower the charging current thus never letting the batteries reach 4.2V

Great little project making good use of other readily available modules. Only thing I’d add would be a temperature sensor on the batteries and maybe an inrush current limiter. Any chance of showing the supply current/voltage during switching on a scope? I’m interested to know if the dip would cause a processor reset on a connected project. Keep up the excellent work and great to see you are training your assistant 😀👍

Hey Sorin can you also do a 5v emergency light? there are 5v 1A usb LED bulbs being sold online now a days and I was wondering if there is a pre built charging pcbs that turn on automatically when not charged.

[@bossybill7437]

I'm not trying to teach anyone how to suck eggs but with UPSs it can be very useful connecting them to the target device via dual input adapters. That way if the UPS needs to be disconnected for a moment, you can parallel power the target device and remove the UPS without interrupting the target device. _Not sue if this device will accommodate that._

[@mikejones-vd3fg]

good tip about poking the eye out, i never had anything hit my eye using dremel tools and what not because i always wear eye protection , except once when iwas cutting a piece of plastic with wire cutters, it literally hit my eyeball and i could feel it ike a blunt force hit on the eye, not a sharp pain, and even felt sore after like a bruise would. watch yourself when cutting hard materials, (actually dont, close your eyes!)

Thanks, this project is simply perfect!!! I Will wait for a variant having also a small 6volt solar panel to keep batteries charged, and the main power just to charge batteries when needed. Of course this variant will not be an UPS but more and offgrid Power source for small 5v projects. Br

[@jacknlogic6500]

Pls make a 12v ver. For modem. I found a Battery Switching Module Board but the Delay is to high

[@ashuntu2010]

Congratulations for a good video. I want to point out that you have not taken care of load sharing when charging the battery with TP module. Since you are charging the battery as well as at the same time you are taking current for output USB so the TP module will confuse and will keep charging the battery. It may not stop charging the battery. Have you seen battery charging stopping upon completely charge ?

[@Sorin_DIY]

Hi. The schematic may be a little confusing. the battery is connected to the boost converter, only when there is no charger input and the relay pins (battery to converter) are in normally closed mode. when the charger input is active, the relay "opens" the battery-converter circuit and the battery is connected only to the TP4056. so the charging of the battery is done separately from the rest of the circuit.

[@maxleon1721]

This one is great, but I wonder if you can redo the 12v one with the same principle

[@Sorin_DIY]

I plan to make a different and better 12V UPS soon.

[@rosekreuze]

very neat project but some of us usually dont have access to jlcpcb in our country but i have a similar board which is YX-X804. only problem is there is about 1 second delay when the relay switched from power supply to battery. im currently using it on my router. ive tried different types of capacitor i was able to salvaged from but non works or the maybe the capacitors used were not have enough juice to power my router? oh btw my router only draws 0.3 amps on 12v if that help solvesbmy issues.

[@Sorin_DIY]

Hi. I'm not familiar with that module, but 1s delay is long, most devices will shut down in that time. you can try with bigger capacitors on the output. or you can make my circuit on a simple perf board, or just solder wires between the components.

[@jadedsoul1]

mega.. Sorin please make a subwoofer Amp for audiophiles with eq knobs, would be a big help to all the people ordering these amazon things that sometimes don't work, id rather build one of yours.. good look. i keep fingers crossed.

[@syedyousufkhandker2670]

hey brother what to do to make this in 12 volt output

[@alexander92ck]

Can you not use the diode to lower the TPM charging voltage the same way you did for the input voltage?

[@Sorin_DIY]

no. it will not work correctly.

[@earumamaadu]

Use inrush current limiter or soft starter to prevent over current issue

[@CTCTraining1]

Yes, I was going to suggest that would be good addition for version 2.

[@lblanchardiii]

Would it be possible to add a push button for battery level check when not plugged in? Instead of flipping the on/off switch.

[@Sorin_DIY]

Yes.

[@richardlighthouse5328]

What is the response time of the UPS? You say it has almost no delay switching between mains and battery power

[@Sorin_DIY]

Hi. it depends on the charger and the load. the chargers have smoothing capacitors that store a tiny amount of energy, which continues to power the relay after the mains power is interrupted. the larger the capacitor, the longer the switching delay time will be. I tested different chargers and delay was 0.2 - 0.5s with no load. if you connect a load to the UPS, it will draw power from the charger. so when the mains power is interrupted, the load will discharge the capacitors inside the charger faster, so the relay will switch faster. in my tests I got about 0.1s.

[@MasKARJ0]

hope you can make 12volt in and out ups with relay, protection undervoltage and overvoltage for battery 12volt vrla/lead-acid, thx 🙏

hi my friend, i love this DIY and maybe i will build one for me, thanks for the idea, maybe if you add a push button to charge the capacitors turn on and on the battery level indicator on demand can solve the issue of turning on and off multiple times to charge the capacitors. I think this can be great for my raspberry pi pc

[@PRATIKFF]

What is the use of diode no. 2 1n4007 in your schematic? What does it do ?

[@Sorin_DIY]

It's used to decrease the voltage that powers the relay from the usual USB 5.1V to 4.5V, so the relay will switch to battery faster, when the mains is interrupted.

[@rahulkalra2126]

great video as always bro .. so if you would have made a 12v model instead of 5v .. would the 12v be able to act as a ups for a 12v router?(i mean the router should not restart on power failure .. that's the kind of ups I want to build myself) .. are you planning to build a 12v model ?

Yes.

[@haydenc2742]

What is the relay switching time..can it be a UPS for say a raspberry pi, can you test if it will drop out when switching please Very cool, definitely need a build and test video on the larger output, this would be a GREAT backup for a raspberry pi or other 5vdc device

[@DrZipZwan]

That why the capacitors are there, they keep the load On in your case, the Pi, until batteries kicks in. Plus relay used here, got a small switching delay, so chance are high to be good for a Pi or any 5V device. You need to check his video he made long ago about Router UPS, last time he used capacitor to maintain load ON and dummy load to fast empty the Power wall charger. This time dummy load is kind of replaced by more efficient relay time. PS: I made the Router UPS based on capacitor & dummy load, for a 9v Router and it is working well. It is basically the same as the router USP, instead this time voltage in only boosted to 5V.

[@Sorin_DIY]

Hi. the switching delay time is about 0.1 - 0.5s, depending on the charger and the load. I don't have a raspberry pi but I'm convinced it will work. but it also depend on the total current consumption, this mini UPS is recommended for less than 1A. because with a higher current the boost converter will heat up and may not work correctly.

[@babylonfive]

Perhaps a different charger circuit module would have adjustable charge levels?

[@rokask]

It doesn't, but it does have a pin 8 that you can pull low to disable the chip (and disable charging). It would need a bit of logic to operate that, but it should be manageable.

The input current depends on the output current/load and efficiency. the max out current is theoretically 2A, but in my tests I got max 1.8A and then the voltage drops. with a high out current the efficiency will be low so it will draw even more current at the input. there isn't a simple answer, you need to measure and calculate everything.
