Ovo sam kopirao sa nekog sajta vise se ne secam ni ja sa koga, pa malo procitajte sto se tice univerzalnih punjaca. Pre kupovine obavezno izracunati dali taj univerzalac moze da isporuci potreban napon, kako se napon racuna i na koju voltazu ga podesiti..
Current output[ampere A] -it has to be the same or higher than the value specified on your laptop.The Amps may be higher but they cannot be lower. If you are purchasing a universal Latitude D410 AC Adapter or Car Charger you will need to work out the Watts of your original Dell Latitude D410 Power Supply and select the universal Dell Latitude D410 Adapter or Car Charger with the same Watts or next highest Wattage. You can work out the Wattage by multiplying the Voltage by the Amps i.e 16V X 4A = 64 Watts. There is no 64 Watt Dell Latitude D410 AC Adapter so you will need to select the next step up which is the 70 Watt or higher Watt Dell Latitude D410 Power Adapter.(NOTE: If the wattage requirement for your laptop is lower than the 64W of the adapter, it will not damage your laptop, your laptop will only take the amount of power it requires. I.E. If your laptop needs 50W, then either the 60W or 90W will work OK. If your laptop needs 80W then you will need the 90W one as the 75W one will not be powerful enough.
Znaci u ovom slucaju se radi o dell d 410 kome je potreban napon od 90W za normalan rad, evo specifikacije jednog univerzalca koje se prodaje kod nas:
- Input DC: 9V-15V, max 10A
- Input AC: 110V-240V, 50-60Hz, max 1.3A
- Output 1: DC 12/15/16/18V, max 5.5A
- Output 2: DC 19/20/22/24V, max 4A
- Output USB: 5V, max 1A
- Snaga: max 100W
Posto ovaj dell trazi 90W ovakav punjac bi trebalo podesti, ako idemo logikom na 19V, posto je original dell/ov punjac za ovaj laptop 19,5V i 4,62A, ali u tom slucaju nece da puni bateriju posto nema dovoljno snage, 19V puta 4A jednako je 76 W. Znaci ne radi se o nikakvom cipu za prepoznavanje punjaca, vec o snazi punjaca. Ali ako ga stavimo na 18V u tom slucaju mora da puni bateriju posto tada daje 99W znaci i vise nego je potrebno.
Znaci dobro pogledati specifikaciju punjaca, a zatim ga i podestiti na odgovarajuci napon...
