if statements working strange

It seems that i somehow meessed with IF statements.

In my idea it suposed to only add impulse when i press q or e and there are some charges, but even if there are none it still applyes impulse As i understand if (1 && 2) ___statement suposed to respond to statement only when 1 and 2 are both true, and ignore it otherwise.

What am i doing wrong? Thanks in advance.

 using UnityEngine;
 using System.Collections;
 
 public class Controller : MonoBehaviour
 {
     public float Speed = 800f; //Speed of movement
     public float Imp = 200f; //Impulse force
     public float MaxSpeed;
     public int charges = 5;
     private float v; //vertical and 
     private float h; //horizontal axis;
     //private float y = 0f; //zero on y;
     private Vector3 MoveVector;
     private Rigidbody rb;
 
     void Start ()
     {
         rb = GetComponent<Rigidbody>();    
     }
 
     void Update ()
     {
         v = Input.GetAxis("Vertical");
         h = Input.GetAxis("Horizontal");
         MoveVector = Vector3.zero;
         MoveVector = new Vector3(h, v, 0); // we need to keep player on a plane
         MoveVector = MoveVector.normalized;
         MoveVector *= Speed;
         rb.AddForce(MoveVector, ForceMode.Force);
         //if(Input.GetKey(KeyCode.LeftShift))
         //{
             if (Input.GetKey(KeyCode.Q) && charges > 0)
                 rb.AddForce(Vector3.left * Imp, ForceMode.Impulse);
             if (Input.GetKey(KeyCode.E) && charges > 0)
                 rb.AddForce(Vector3.right * Imp, ForceMode.Impulse);
             //if (Input.GetKey(KeyCode.W) && charges > 0)
             //    rb.AddForce(Vector3.up * Imp, ForceMode.Impulse);
             //if (Input.GetKey(KeyCode.S) && charges > 0)
             //    rb.AddForce(Vector3.down * Imp, ForceMode.Impulse);
         //}
     }
