I recently purchased a usb splitter y cable. It is a male to 2 female usb splitter. I used it to connect to my power bank and it adds enough draw to my circuit to keep the power bank awake. Apparently there is a chip in the splitter junction (not just wires) that added enough extra load. It was a very pleasing and unintentional fix to my problem! For reference I am plugging a small Garmin cycle computer into my power supply that, on its own, kept powering down along with the power bank. Now with the USB splitter Y cable it stays on.
Thank you so much for this info! I don't have a splitter cable atm, but after reading this went and tried a USB hub i had stored somewhere and it also worked. A bit heavier than your Y cable but enough for me to power a tiny synth continuously from my powerbank, for now.
Using a BSYYO power bank to power a Pi Pico project and came across this power shut off problem, thanks for posting its still helping two years later! I tried 2x 220R but no luck but 2x 180r works fine.
This worked great for my project. I have a small device on my telescope which only draws a fraction of an amp via USB. I used to have an old, cheap battery which didn't shutoff, but it went out and all the new one's I find shutoff after 20 seconds. A little prying with a small screwdriver, two hits with a soldering iron, and adding the tape as insulation and I'm in business. It took me all of 10 minutes after the iron was heated up. Thanks for the tip and detailed instructions!
Why you did not connect the resistors to the output USB port of the USBdoctor so that you see the current draw of your resistors indicated on the LCD screen of the usb doctor? I am curious if it would fit if i add a 555 timer circuit in an attempt to pulse and reduce the lost power to the minimum.
Thank you for this tutorial. I couldn't get my "lipstick" charger nor my two flat XPCL batteries to work but, before giving up, I used an older Powercore 10000 that I had lying around and that one worked just fine. Not sure why the other 3 batteries wouldn't work, though, despite using the same pair of 220Ω resistors. Edit: I did finally get the other 3 chargers to work with 4(!) 220Ω resistors (55Ω).
Hi Will. I found an easier way is to use an USB Y splitter cable (1 male to 2 females cable). To make the power bank awake, connect a mini globe of 6 volt 100mA to one of the female socket, then my guitar pedal to the other socket. It works.
I need a mini globe I am not an electronics guy...(I don't know for sure what you mean). Do you mean a mini disco light usb power ? or something else? Is there anyway you could add a link or hint?
Good idea. Thanks for this video. I used this mod on my power bank. 100ohm resistor not good value for my power bank. I used 62ohm resistor. It can drain 80mA.
I tried it with ATTiny chips/boards and a few LEDs running a simple Arduino sketch. I used a 100ohm resistor and after it ran for a few minutes, the resistor started getting hot. I tried both higher and lower value resistors but the lower resistance got hotter faster and higher values still resulted in the power banks tripping off again. How did you cope with the excess heat? I really can’t have that in my projects. It could be a fire hazard! 🔥 I also just tried 2 220 ohm resistors and they’re getting hot too.
At 5V and 100ohm, you are dissipating 1/4W of power. If you are using a 1/4W resistor, you are over the rating of the resistors. If you are using 2 @ 220ohm, you will be at 1/8W of power which is in range for 1/4W resistors. It is important to use the right rating resistors. They definitely should not be getting hot if you are using 2 resistors at 200ohm each, rated for 1/4W. It is possible that something else is wrong.
could we transform the voltmetre you used in the video by removing inside it. And put an ardunio nano in it to draw current say once in a 10 seconds(my powerbank can power low for like 2 minutes, so I can do it one in a 2 min). So that we consume less energy? I saw that arduino nano consumes 20 ma power so maybe more efficient?
Hey Will I tried this and it works great! Thanks for the video! My powerbank used to shut off in about a minute but now it's running for a lot longer. However, I see that it still shuts off randomly after a certain amount of time (10-15 mins). I manually turn on the powerbank at that point and it still has plenty of charge to keep going. Any idea how to fix this? Add another resistor?
You could test it with a lower resistance, just be super careful with the resistor's heat rating. However, I doubt that will fix it. It sounds like your power bank may have more power-saving measures and may require a large, constant current draw (like 500mah or more).
@@Bluemonkeydev Thanks! I did add a 3rd without any heating issues but then the power draw was high enough to drain my powerbank rather quickly. Couldn't use it for what I wanted but thanks for the very helpful DIY video!
I'm actually having the opposite problem. My bank wont shut off when my raspberry pi is put in sleep mode. It's only draining it by .2 amps but still, I'd like it to turn off but i have no idea what the name of what id be looking for is.
This kind of method is not usable for my purpose: running an Arduino on battery with deep sleep. Based on the calculation in the video, it uses 50mA on its own. Meaning that in just one day, the resistor will consume 1200 mA. It can be useful for maybe running an Arduino for hours in human attendance (that you will manually turn it on/off).
Yes, I agree, this is not a usable solution for your use case. I would use an HT73XX voltage regular and a few batteries in series to solve that problem.
I enjoyed your video. I would like to keep my 30000 power bank on to power a Blink Mini camera overnight. I will need to keep the power bank active so it will stay on. It has 3 usb ports, so can I just use those 100 ohm resisters and plug them in an available usb port with usb plug or cable?
You could - however, it will burn 50mA on just the resistor. A better solution would be to build your own battery pack with a boost curcuit that doesn't cut out. But that might be beyond what you want to do.
Yes, there was a time when I could have made my own.Is Your design a better option than mine or is the outcome the same? I guess I could try it and see how much impact it makes on my power bank.
It's not a matter of better or not, it just comes down to efficiency and purpose. This purpose was for a small, short-term use device where you don't really care if you waste some power on heat. I recently built a custom battery pack for a project that needed 9V. I used 9 18650 cells (all in parallel, 3 groups of 3 each) each 3-bundle I used a small protection board AND a master boost/charge module. The boost module is super efficient so it should run for a long, long time on a single charge. The project was pretty straight forward and the costs were under $3 (salvaged batteries)
Actually, if the purpose of the added circuit is to trick the power bank into detecting a load, then use your cellphone as the load by playing music or view a RUclips movie while charging at the same time. I have done it and it worked.
This is an unnecessarily complicated circuit. I have shorted the timer lead coming out of the IC and it works OK. It does not consume any extra power. The timeout circuit is there for a purpose as not to waste power.
I purchased the usb doctor that you put on your link and purchased the 2 resistors. My question is, just to make sure. do i solder the resistors to the same spot on the doctor since its the same item? If not, how do i tell which is the 5v and which is ground? Thanks in advance
So I did exactly what you said to do but my anker power bank is still shutting off. I know nothing about resistors so was wondering what size resistors I should try next. Thanks in advance
@@Bluemonkeydev Ah, alright. I was only using resistors I had on hand. I have tried using two 220R, but it would pulse on and off my power bank if it was just the USB and resistors. I haven't tried with 4 resistors since I wasn't sure.
Capacity of the battery has no influence on the resistor. The protection circuit could test current through measurement of voltage drop through a known fixed resistor. This means that what you want to ensure is a min current is exceeded. The current is I=V/R, higher the voltage higher the current, so if your powerbank outputs 5V, I=5V/R. 100ohm resistor will still draw 0.05A=50mA, which is probably above the min. current. If a larger current is needed you can lower the resistance by using 2 100Ohm resistors in parallel, giving 50Ohm total resistance and 0.1A current draw... which is actually quite a lot! 2000MAh LiPo cells store about 7.4Wh of energy, 0.1A*5v=0.5W power consumption, which means your power bank will be dead in under 15 hours, even if nothing is attached to it! Note: As mentioned in the video 100Ohm 1/4w resistors should be fine IF ENOUGH AIRFLOW IS ALLOWED... otherwise go with 2 200Ohm resistors in parallel, giving 100Ohm resistance AND 1/2 Watt power rating (since each resistor is only seeing half the current)
Great way to waste of invaluable battery capacity. While running arduino with battery power, every single miliamp is important for me. I suggest you write a blink code with 10 seconds interval. And short the output pin. This way you will have 10x profit.
Hi, this could be the answer to a problem I've had. I'd like to run one of these rechargeable packs on a project but, I need to have the power from the power bank available always. The project has a remote control but, the need to constantly reset the power bank is a nuisance. How could I calculate the life span of a fully charged battery pack with a constant draw from the resistors ? Thanks in advance for your help..
*I have NO idea what you mean by “overwrite” a battery pack. It’s not data. But instead of wasting / draining the pack with resistors, use a pulse circuit like Mr. Carlson’s.* ruclips.net/video/lOL3ic8msas/видео.html

4:01 *It’s not a “trick,” it IS an actual (wasteful) load.*
So you didnt mod the powerbank or overwrite the auto-off so this video is nothing to do with the title. well done

When using a power bank to power an LED light, Can you configure the power bank to automatically shut off after 5min?
I did the same thint with 200ohms resister it worked well thanks a lot man
The resistOr is a waste of power!

Use a multimeter to confirm before soldering.

Why can’t they just make a power bank with a physical on toggle switch 🤷
I wanna know the lowest energy consumption way. Need an upgrade version!
Use smd resistor instead.. Maybe with a smd led too.
I am new to this, would two 220R and two 2200R, all in parallel function the same as using two 200R resistors?
Hmm, well that's a weird way to do it. I would not suggest that, there is not a ton of room in those chargers. Why not just two 220R in parallel?

it did'nt work for me i did axacly and stile turning off after 30sec
If the power bank has a on/ off button just hot glue the button down.

Not a good idea to have bare resistor leads running close to the underside of a PCB. Use heat shrink sleeving!
Is there anyone who can sell me the above as finished product?
This is so frustrating. It’s literally what they’re made for, and won’t charge my phone.
