We propose a simple encoding of charge-based quantum dot qubits which protects against fluctuating electric fields by charge symmetry of the logical states. We analyze the reduction of coupling to noise due to nearby charge traps and present single qubit gates. The relative advantage of the encoding increases with lower charge trap density.
