I have no idea what Pack 2 means in the description, but it doesn't mean that there are 2 cables. now I have to wait another week for another one to arrive. ### ⭐⭐⭐⭐⭐ Fit for work *by on Reviewed in the United Kingdom 9 July 2022* Can use the old ThinkPad power adapter for newer ThinkPads ## Frequently Bought Together - Hayatec Square Tip power Converter to DC 7.9mm Charger Adapter Cable For IBM Lenovo ThinkPad X1 Yoga Carbon - Power Supply Converter Cable Cord - Laptop Power Adapter Round Port to Square Port 5.5mm - Crucial RAM 16GB DDR4 3200MHz CL22 (or 2933MHz or 2666MHz) Portable Memory CT16G4SFRA32A - Silicon Power SSD 512GB 3D NAND A55 SLC Cache Performance Boost 2.5 inch SATA III 7mm (0.28") Internal Solid State Drive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/56507537-hayatec-square-tip-power-converter-to-dc-7-9mm-charger](https://www.desertcart.gr/products/56507537-hayatec-square-tip-power-converter-to-dc-7-9mm-charger) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-15*
