dear sir can you recommend good 20000ma (or larger if needed) power bank for the new gen. cell phone fast charging or for general purpose ????? thank you
Are you familiar with the Japanese transistor numbering conventions? Part numbers all have "2S" implied but not usually marked. Those starting with A or B are PNP devices, those starting with C or D are NPN. Fets are J or K. I'm not sure about E through I, although I'm pretty sure things like unijunction transistors are in there somewhere.
I have the TOPK cable with 5 pins for data transmission. Honestly it naturally aligns with the socket so shorting is nothing to really worry about.
USB-C Negative is the 4 on the ends, positive is the 4 in the middle, Or 4th pin over (towards the center) from the negative/ends on a standard data cable, that one is a power only.
Why do companies scrap off the part numbers off the chips? Makes me wonder if they are sub-standard parts that did not make the cut so they ground them down and resold. Would like to hear if there is a real reason for doing this besides corporate espionage.
Lightning connectors actually require certification from Apple (and a chip to be integrated on it), so I wonder whether that's certified or not.
I believe "2pcs" meant that it was for two capacitors in series… You know, Chinglish can be confusing and misleading…
Julian, that PCB ad states clearly, 'Qty: 2 pcs'. The description says that it is for '2 pcs 5.4V 3000F Supercapacitor….', so they're correct, if misleading. You chose to pay $11 for 'Qty: 1', so you'll have no case, if you raise an issue. Simply put, you've been had by not understanding the craftily-chosen wording.
The Lighting cable would short out the connections it’s should be double sided
It looks like the "2 pieces" aren't both voltage protection boards the one is purely to connect the other end of the axial capacitors together – so you didn't get 2 pieces but the second one is dodge anyway 🙂
Clearly the fault of the PATRIARCHY. Right Jules?
The magnet will render the compass inaccurate (As do most phone wallet fasteners)
