As soon as it fits in the work and the laboratory space is free, I will determine the current flow at the 12V socket when 2B is working. However, given the current situation, this may take a while ...
I had a problem with my smartphone charging slowly with the manufacturer-supplied 2 A adapter, so I bought this. Although USB 2.0 is not supposed to output more than 5 V, this is widely ignored for "customer convenience". My power bank can be switch selected to supply 9 V or 12 V through its standard USB connector, though it defaults to 5 V when turned on.

The linked device is rated up to 30 VDC at 5 A. If one wants to wait, it can be ordered from China eBay sellers for a lower price.

Good morning, I wanted to comment and ask about what you are talking about, a few days ago, I bought some 9V rechargeable batteries, I use my unit connected to the current with its adapter and it is powerful, I like that energy, I tried the battery and it works Okay, but for me it lacks energy.
Stimadict you who have the powerbank, does the power feel as if the Series2B is connected to the electric current?
I am looking at the powerbank model and I see that the seller does not send it to Spain, I think it must be due to the problems of the batteries, although if they are empty they should not have problems. Greetings and thanks

Yes, it feels *exactly* the same.

All of these powerbanks are made in China. You should easily find another seller who sends to Spain. Any 12v powerbank should be ok.

suso, I hope you are well with the virus in Spain. Stay safe! :)

Hello Stimaddict, I appreciate your words, we are very careful, I am the only one who goes out to make very punctual purchases, once a week. I have seen that they also have one very similar to yours on Amazon. What I want is to have more security and not be connected to the current, although this is the transformer, and if that power bank works and as if it was connected to the current, I will look at it and that money from the sale soon, I will use it to this. Health

Good morning, after reading, see the characteristics of the power source supplied in Pack 2B, I saw that the PowerBank gives you 12V the same as the power supply of the Stim 2B series. Thank Stimaddict for the advice he gave me. I decided to buy a Power Bank too, it gives me more security and peace of mind than having the source turned on with the Series 2B, in bed while using it. Just as I tried a rechargeable 9V Lithium battery and not feel the power of the Series 2B as with the source with the PowerBank I can rest assured that if I want to leave everything plugged in at night and try to sleep, nothing will happen to me, while with the power source had that fear.

Hi,
which Power Bank did you buy and what is your experience with it?
At the moment I also thinking about a PB.

Thanks!

Hi,

i'm also using a USB Power Bank.
But a relatively cheap (about 20 bucks) USB-C to power my 2B for nar one year now.
For that i used a 12V PD USB-C Adapter and a small condenser to even more smoothe the Voltage and make some room for currentspikes.

Before i connected it to the 2B i tested it with a DC load and the oscilloscope proved the stability of the source to 12V +- 0,15V.

At 52800mAh capacity running at 12v on Hi-Power I would guesstimate around 25 hours of use between charges.

That's based on my own 12v powerbank: https://www.e-stim.net/viewtopic.php?f= ... 259#p16198
25 hours... that will do me :lol: seriously though could anyone stay connected to thier 2b for a whole day? :geek:
