Ac Adapter Universal Laptop

After the original AC Adapter sold with my Lenovo ThinkPad broke, I replaced it with a universal adapter. I was told this would work just fine. That was a big mistake! While the universal adapter charged my laptop for a while, it stopped charging after a couple of months. Worse, it actually contributed to power discharge rather than positive charging. The Lenovo 65 W AC Adapter was exactly the right accessory and it worked instantly. This one even seems even stronger and less wobbly than the original. It was the right choice.

AC adapter works very well!

It is an AC adapter... I can only say it works...

I lost the original adapter that came with the laptop and tried to replace it with an "all model ac adapter" - however, the replacement adapter didn't work properly. After purchasing the Lenovo adapter my T580 is alright and working fine.

We have a n router, not an AC standard router, but, compared to the adapter built into our relatively new laptop, the wireless download speed increased from about 20 Mbps to 36. Our hard wired service from Comcast into the router is about 85-90 Mbps so there is speed loss in wireless, but it's much less with this adapter than the one that is built into our Dell laptop. Plus, if we ever buy a new router, (and possible upgrade our Comcast internet service), we may be able to take advantage of the higher AC band speed.

This hard drive is optimal for frequent travelers who need to reliably access their data while they are away from home. The drive is robust and stable, and can withstand a certain level of stress when put in a laptop bag/backpack that's squeezed or ungently handled. I had other portable drives break all the time, but not this one. Also, although it supports USB3.0, it does not need an additional AC adapter but instead comes with a cable that has two USB plugs for the laptop. Therefore, you won't need to carry an additional AC adapter around at all times. Although the drive is slightly bigger than some other harddrives of the same capacity (because it has a protective casing) it is not really heavier. The far superior robustness of this drive justifies the slightly increased dimensions. Great investment, A+

great ac 2 dc power adapter!

Compact universal travel adapter with surge protection

The adapter converts the AC to required DC as advertised.

This fit perfectly on my Nikon Z5 and Celestron Universal 1.25 T adapter.
