zdyCGTime90 Degree Angle DC5.5x2.1mm Male to Female Adapter DC5521 5 Volt DC Barrel Power Jack adapter Coupler power head Connector for Tablet/Monitoring/Router.(DC5.5x2.1mm)(2pack)

Received in 1.5 days after ordering, and gave it a quick test. It works with traditional Thinkpad models around 2011, including X201, T520 etc. To repair the power adapter, I just soldered a common 5.5x2.1 male connector (like the one used for WD external hard drives) to the broken Thinkpad wire. The soldered connector fits the female connector here. It may be the cheapest repair, and the price for each unit ($5) is not too expensive at Amazon (I meant it is not cheaper craps from ebay).

Necesitaba 90º en un conector. El único problema es pagar por dos y el segundo no me tiene utilidad.

There's not a lot to say. The fitment of barrels is satisfactory and the construction leads me to believe these would carry the max amperage on a 2.1mm barrel design. The listing says 5 volt, but these could be used on voltages up to 24 volts, provided you do not exceed the max current draw. I would buy these again.

Use two of them for my two LED microscope lighting DC volts

Both my wife and I have Lectric XP 3.0 folding electric bicycles that we take camping with us. We keep them in a large plastic tote in the back of my truck. After a ride, I would remove the batteries before we placed the bike in the totes, then I would recharge the batteries back at the campground. Once, we almost left the batteries at the campground prior to a ride because we forgot to put them back in the truck. I did not like removing the batteries from the bike after every ride, and potentially damaging them transporting outside of the bike.I thought that a right-angle adapter placed into the charging port might fit in between the folds of the bike frame and still allow the charging plug to fit. Well, it works, after a ride, I just insert the adapter into the charging port then fold the bike. Back at the campsite, I insert the charging plug into the adapter.I can now charge the batteries in the bike while they are in the tote in the folded position.
