Lenovo Ideapad Y700 - 15ISK New Charger Help

2021-01-12, 19:36 PM

My original charger for my laptop charger began to fray so I purchased a new one from a tech company in the city. I made the mistake of quickly checking it over and thought it was perfect till I got home, realized it was a bit off and that they don't accept returns. I was hoping you guys could help me by letting me know if I can still use the charger or if I should just go ahead and buy a new one. 

 

The original charger model is: ADL135NDC3A with an input of 100-240V~1.5A 50-60Hz and an output of 20V --- 6.75A

The new charger model is: ADL170NLC2A with an input of 100-240V~2.5A 50-60Hz and an output of 20V --- 8.5A

 

I was only told that the voltage was supposed to be identical which it is, but the difference is the smaller decimals near the voltage. I want to be completely sure it won't fry my computer or just not work. Thank you guys for your help.

Solved! See the solution

Welcome to the Community

 

As long as the voltage and connector are the same, the higher wattage won't matter. The computer will only draw what it needs up to the maximum output of the charger. Replacing a 135 watt charger with a 170 watt charger won't make any difference.  Going from 135 watt to a 45 watt charger will result in slower charging and battery drain even when plugged in.
