Having an extra charger or a universal charger can greatly extend a player’s ability to stay in the game. Two things you have to look for when purchasing a charger are that the voltage is the same as your battery and that the connector is the same size. A 9.6 volt charger can damage an 8.4 volt battery so it is important to check that they are the same voltage. Most airsoft batteries use a larger or small Tamiya connector so your charger must have the same size. There are also universal chargers available which can charge a range of voltages and come with adapters for different size connectors. These types of charger are very popular since they lessen the chance of accidentally hooking up the wrong charger to the wrong battery and causing damage.
