Rob23 Posted June 18 Share Posted June 18 Exciting news coming from 'The Monday Club' re the smaller power bank. Hopefully it wont be too long to wait. Jenny has one to test which can be seen here: https://m.youtube.com/live/mRSyfW728Vo?si=Lr_-DZmVfGw4aFGd&t=85m47s 1 Link to comment Share on other sites More sharing options...

Rallymatt Posted June 18 Share Posted June 18 That is significantly smaller than current and many others. Carl said it was 40% smaller at least. 1 Link to comment Share on other sites More sharing options...
Too Tall Posted June 18 Share Posted June 18 Looks like just 2 capacitors ? Be interesting to see how it compares, but looking very useful. Link to comment Share on other sites More sharing options...
ateshci Posted June 19 Share Posted June 19 (edited) It's the usual circuit of 2 capacitors in series , my educated guess is a total capacity of 0.15F. In combination with the step-up circuit delivering somewhere in the 9--10V range, you can expect 1-2secs at 200mA. In this forum, I have shown a similar circuit meeting space and time requirements, and fitting into the smallest TT models.

Too Tall Posted June 20 Share Posted June 20 Will this have a new part no. or is it retaining R7377 ? Link to comment Share on other sites More sharing options...

It will be the same SKU just to confuse you and retailers. Thankfully/unfortunately** there are none of the old ones left in the supply system so the new ones when they arrive will be only ones. ** I liked the old ones with their run on for ever characteristics so I will miss them.

dBerriff Posted June 22 Share Posted June 22 That is more like it for us TT:120 modellers. I accept that perfect track-work is the goal but while I get there this will help avoid the dreaded Bluetooth reset. 4 Link to comment Share on other sites More sharing options...
Rallymatt Posted June 23 Share Posted June 23 It was good to hear Jenny refer to potential issues with excessive run times on PB’s the shorter time on the new smaller PB should be a much safer option. Link to comment Share on other sites More sharing options...
96RAF Posted June 23 Share Posted June 23 The long run time was a side effect gimmick on the old PB. The new one performs well in a more realistic user environment, e.g. traversing a rack of several back to back points from a fiddle yard at very slow speed. More details will be posted when additional video from the test team is edited. 1 Link to comment Share on other sites More sharing options...

There are no old ones to be found, unless the scalpers have any. All the regular suppliers are nil-stock. 1 Link to comment Share on other sites More sharing options...
DuTTchy Posted June 23 Share Posted June 23 Interesting little power bank, hope this will fit in the 08 shunters. I'm a bit curious about the capacitance of the capacitors, does anybody know this yet? Link to comment Share on other sites More sharing options...

Kenneth-365689 Posted June 23 Share Posted June 23 I've just placed a pre order for 5 as I also have pre orderes placed for a jinty and a green 08..and as I have decided to make a small OO gauge layout (wash my mouth out with soap and water) using 0 4 0 pocket rockets to recreate something like the Mid Suffolk, I think the extra 3 will come in very handy.

If i'm correct these 2 capacitors 1,0F / 2,7v in series have the same value as a 500μF / 5,2v capacitor? Link to comment Share on other sites More sharing options...
david_watts1 Posted June 23 Share Posted June 23 All I want to know is: Will they fit in the new shunters and the 08? Link to comment Share on other sites More sharing options...
