TekkPerry 96W Universal Laptop AC Power Adapter Charger with 18 Adapters 12V-24V Compatible with Notebook Acer Asus Toshiba Dell Lenovo IBM HP Compaq Samsung Sony Gateway Fujitsu Mobile Phone LCD DVD

There are two sets of tips. One set has two needles at the end and goes directly into the adapter cord. The other set has just one 'needle'. At first, I thought it was screwed up since the tip I needed only had one needle.However, there is one tip on the 'two needle' set that fits the one needle set, sort of an adapter. So you first put the "two needle tip" on, then attache the correct "one needle" tip on top of that one.I'm not sure how long it will last; it doesn't fit very snug into the laptop power slot. Time will tell.

I will say this about the product. It did charge my laptop. But only once. The charger literally fell apart the following day.

While this is a 3rd party power supply alternative for laptops, I'm using it to power my model train. I thought I'd take a chance and see if any of the supplied connectors would fit the Lionel system. And yes, one of the connectors did! The great thing about this is that it's half the price of the power supplies made by Lionel and with more wattage. So far, I've been using this power supply for two months and there's been no problems. It's also versatile enough that I can use it for my laptop and a few other electronic devices.

Gets super hot!!

My work laptop T460s has a usb connector for power adapter. This works well for this type of charging connection.

I bought two of these a month ago, neither now function. The smaller pin on the adapter head has broken on both of the adapters. I did not change the adapters after purchase. Just wear and tear of unplugging the laptop seemed to cause them to break. Very poor quality. Avoid this product, it is a complete waste of money.

Seller falsely advertised 18 adapters for this universal laptop charger. Only 8 adapters actually connects to this charger. The remaining 10 adapters has a circular head, which isn't compatible with this charger.

This is the worst item I've ever ordered from Amazon. The charger stopped working the day after i bought it.
