Review on Universal Charger ThinkPad Notebook Computers by Susan Stephens

This is a fantastic tool for people who need to work in remote locations using different computers. Not only does it work in the car for road warriors who have deadlines to meet or watch a lot of videos, but also makes it easy to switch off power from other DC sources without an additional inverter. In my case, I do a lot of live streaming and need to power my laptop for hours, usually too far from an outlet to charge it. So I carry a portable power bank with 12V DC car outlets and it's PERFECT to use with! Please Note: While my Lenovo and HP laptops immediately identified the correct connector (yellow square and blue tip). , my Acer was a bit tricky. Each plug has a voltage rating (printed on the plastic) and I found one that fit but was 0.5 volts too low. It usually works if it's within spec range, but in this case it will power the laptop but not charge it. It wasn't until I opened the brochure and saw a list of various specifically numbered earbuds with compatible models that I realized there was a better match and having switched to this one I'm happy to report that my Acer was thereafter well charged that. I took a photo of the brochure for reference and am uploading it here. It's also interesting to note that I own both an MS Surface and an older Macbook Pro magsafe, neither of which includes the tips found in this set. Strange, because these are popular laptops. These aren't the ones I use for live streaming though, somehow all I have have plugs included here. But I think it's important to point out that some popular models are left out in case you need assistance. If you own any of the laptops on this list, this is a great product!
