After 5-6 months of use, it suddenly broke down, stopped working, and gave up. At least it didn't take my laptop with it, hence the one star.

Fits perfectly in the computer slot and seems to have the same durability and speed as the factory one. At 1/3 of the price, I don't think you even consider it...

This charger is of very poor quality. I bought it for a 65 Watt Laptop (based on the original charger and specifications) and it worked for almost half a year. Then it started to randomly start and stop charging on its own with a very high frequency, while the power indicator light remained on. I bought the same charger a second time, thinking it might have been a coincidence or that the first one had experienced a power surge, but the new one behaved exactly the same after 1-2 weeks of use. Since the second one was brand new, I thought maybe the laptop had a problem. However, in the end, I got another charger with the same specifications and it works perfectly. I recommend not buying this charger because it took me a while to realize that the issue was with the power supply (and not the plug or the laptop itself) and it damaged my battery. In a short amount of time (1-2 months), the laptop went from holding a charge for 2+ hours to barely lasting 1 hour.

It does not fit in the laptop port. It fits occasionally and only if I apply excessive pressure. I would not recommend it as it is "if it fits" and does not fit well. I would suggest moving towards a Universal one.

I am satisfied with the charger and the service of the site, but I was expecting to receive the part that connects the charger to the power, which did not come.

Absolutely compatible with Lenovo B50. Better than the original due to its shorter cable length that does not constantly twist.
