This enables pass-through mode. Of course you can double-press the power button if you need to adjust the DC output if needed. Just remember that when you plug in the charging cable for the battery pack, it will immediately shut off the output until you turn it on again. **Q: how does manufacturer come up 50000 mah ? what cell using ?** A: I believe that is at 3.7V, so 50,000mAh * 3.7V = 185 Wh. **Q: Does it/ can it be used to change a Surface pro 4** A: Yes. It can charge Surface pro 4 which is 12v. DC output: 5V/8.4V/9V/12V 3A (max) 16V(16.5V)/20V(19V, 19.5V) 4.7A (max) But we don't include this adapter. You need to buy an adapter or a cable by youself. Thank you. Have a nice day! **Q: Pretty sure this cannot be checked in a aircraft baggage. Kindly clarify if this is allowed as a hand luggage on an airplane provided its power?** A: Dear customer, this power bank is 185Wh and you cannot take it on plane, even a hand luggage. You can buy Krisdonia 25000mAh which can be taken on plane. Thank you. Have a good one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on March 7, 2024* ### ⭐⭐⭐⭐⭐ Review *by A***R on April 16, 2022* ### ⭐⭐⭐⭐⭐ Review *by L***Z on January 7, 2023* ## Frequently Bought Together - Krisdonia 50000mAh Laptop Power Bank 5/9/12/16/19/20V Portable Laptop Battery Charger with QC3.0 USB-A Port & 12V Type-C Port for Laptop, Tablet, Smartphone and More Devices - ORIEMARS USB Laptop Light with Adjustable Gooseneck, 3 Color x 3 Brightness + 3 Mini LED Lights --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/46813009-50000mah-laptop-power-bank-5-9-12-16-19-20v](https://www.desertcart.vu/products/46813009-50000mah-laptop-power-bank-5-9-12-16-19-20v) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-07*
