This 20-centimeter DC adapter cable adopts 4.5×3.0mm male output and 7.4×5.0mm female input, which enables you to reuse old large-size 7.4×5.0mm HP power bricks to charge new slim HP laptops without purchasing a dedicated new charger.
Low-resistance internal conductors sustain consistent current during all-day continuous charging. Soft scratch-resistant outer insulation resists aging for daily office and home use. Reinforced plastic connection joints effectively prevent wire fracture from frequent pulling and twisting.
Plug-and-play without extra setup. Medium-length lightweight design is convenient for desktop placement and business trip backup, providing an economical power conversion solution for HP laptop users.
