Nova NHC-1046 is a beard trimmer , it works on 220-240 V, comes with a removable and rechargeable battery, the performance is quite below average and its not even capable of completing even a single beard trimming session with average hairs, its battery backup quality is really poor, once after charging it works for only 5-8 minutes, once after using it takes approx 4-5 hours for recharging it for re-use. I will never prefer anybody to buy this product. The Company should improve the battery backup and performance of this product.
