Buying checks for the United Kingdom
Regional hardware: Match AC voltage, frequency, socket layout and the exact regional model code. A shared product name does not guarantee shared hardware. Charging bundle: Check whether the AC lead, car lead, solar cable and any connector adapter are included. A pictured cable is not always part of every regional bundle. Warranty and returns: Confirm that the seller is authorised for your destination and where a heavy lithium battery must be returned for service. True delivered cost: Compare product price and shipping first, then check taxes, import duties and remote-area or oversized-delivery charges before paying.
