The correct approved AC adapter for a Nitro notebook can be identified by looking at the DC Rating label on the bottom of the notebook. </p> 19V @ 4.7A corresponds to the 90W adapter. <br><br>19V @ 7.1A corresponds to the 135W adapter<br><p><br>The 90 Watt blue tip adapter has a smaller hole. The 135 Watt orange tip adapter has a larger hole.<br><br></p><p><br>If the larger orange tip 135W adapter is used with a 90W blue DC-in port notebook, the 90W notebook may have problems powering up or charging the battery. The smaller DC-in port pin on the 90W notebook doesn't make good contact with the larger hole on the 135W adapter.</p> <img src="https://us.v-cdn.net/6029997/uploads/migrated/acer_final/41132/adapter.png" width="600" alt="image" class="embedImage-img importedEmbed-img"></img><meta content="#Aspire VN7-792G,#Aspire VN7-572,#Aspire VN7-572G,#Aspire VN7-592G,#Aspire VN7-572TG"></meta> </article> </main>
