Fast shipping. Received without damage under the combined delivery method. The charger meets my expectations perfectly. It does not heat up while charging like the original tool. The LED changes from red to green when charging is complete. I will place another order. Very satisfied with the purchase.

Good charger for its price. I give it four stars because the device's capacity is 20 watts 1A, instead of the stated 2A 21V
