Hardware Trust 16895 Universal Laptop Charger

Anybody have any idea regarding this...

Never having seen the Trust PSU, I can't comment on the different tips; but I suspect they 'tell' the charger what voltage to put out. (I.e it knows which tip the the Tosihba uses & adjusts o/p accordingly). With regard to the power/current question, the Trust is probably better than your original. The 3A quoted on your old charger is the maximum it will deliver and, as it is original to the laptop, the laptop will never demand more that 3A. Your new charger can potentially supply up to 6A, but as the laptop will never demand that, your new supply will never be working more than 50% of its maximum capacity. A bit like a 12V car battery can potentially supply up to 900 amps (starter motor) it won't damage a 0.5A bulb, so long as it is also rated at 12V.
I actually have a couple of old Toshiba laptops on the "too good to chuck out" pile, at least one appears to be quite resilient to over-voltage as it happens, I had it working away quite happily for months on a standard 19V supply before I noticed.

You normally need to make sure the voltages match, in this case the charger automatically decides the correct voltage.

Next make sure the charger amps is higher then required by laptop. in this case the charger can manage 6A @ 15v which is fine. Your laptop will only draw the amount of amps required, 3amp in this case.

Looking at the manual here,

Seems to indicate that if you have a 15v toshiba device like yours then use tip D.

I understand and I do agree but since there only is one 15v tip that makes it easy for 15v chargers, it will always be that tip but I have two tips that say 16v with one having an E and the other an R above it....Then I have 7 tips, all saying 19v, but having an E, G, K, N, P, T and X above...the one that has a K also says V4 on the back....

there ore must be some explanation for these letters, trust seem to be Australian I find no uk support site, will see if they can offer some help....

Do you have a tip with D on it ?

Does it fit ?

Yes the 15v, d tip fits but what do these letters mean.

Letters seem to correspond to different manufactures and different voltage if the same manufacturer. As I said, the manual says if you have a 15v toshiba then use tip D, I am not sure why you are trying to second guess the manual ?

did you check cprst

Ah I see now. I never got the manual and your link seems to be a location on your c drive. I've googled for the manual and makes perfect sense now
