Both USB-C ports combine for up to 190W, and all three ports (2× USB-C + 1× USB-A) share up to 160W ? enough to charge your laptop, phone, and tablet together in one go.\n- 20,000mAh HIGH CAPACITY: Built for full days out and long trips. The 20,000mAh cell keeps your phone alive for days and a laptop going through a long-haul flight ? ideal for travel, commuting, and busy workdays.\n- BUILT-IN RETRACTABLE CABLE: No loose cords to pack or lose. The integrated 29.5\" (75cm) braided USB-C cable pulls out when you need it and retracts into the body with a simple pull-and-lock, so the cable is always with the power bank.\n- 2.01\" TFT SMART COLOR DISPLAY: Check your status at a glance. The 2.01-inch color screen shows 6 panels ? real-time output, temperature, and battery health, plus adjustable brightness, sleep timer, and language ? so you always know how much charge is left.\n- FLIGHT-APPROVED \u0026amp; AUTOMOTIVE-GRADE CELLS: Made with 21700 automotive-grade cells for stable output and a long lifespan. Rated at 20,000mAh (72Wh), it meets TSA and airline carry-on rules under 100Wh, with multi-layer protection against overcharging, overheating, and short circuits.\n\u003c\/p\u003e\u003cp\u003eProduct description\u003c\/p\u003e\u003cp\u003eWhy does the power bank charge fewer times than expected?\u003c\/p\u003e\u003cp\u003eDoes fast charging affect the rated capacity?\u003c\/p\u003e\u003cp\u003eWhat does “190W MAX FAST CHARGING” mean?\u003c\/p\u003e\u003cp\u003eDoes fast charging work with all phones and laptops?\u003c\/p\u003e\u003cp\u003eWhat are the dimensions and weight? Is it too heavy?\u003c\/p\u003e\u003cp\u003eWhy does the power bank charge fewer times than expected?\u003c\/p\u003e\u003cp\u003eSome energy loss (typically 30 - 48%) is normal during power conversion because of battery and circuitry design. After conversion, a fully charged 20000 mAh power bank provides about 10490 mAh to your devices.\u003c\/p\u003e\u003cp\u003eDoes fast charging affect the rated capacity?\u003c\/p\u003e\u003cp\u003eYes. At 9V\/12V fast charging, rated mAh may be lower, but Wh energy is similar. Higher voltage means more loss and heat. Actual performance varies by device, cable, temperature, and use.\u003c\/p\u003e\u003cp\u003eWhat does “190W MAX FAST CHARGING” mean?\u003c\/p\u003e\u003cp\u003eBoth USB-C ports can combine for up to 190W. Actual power to each device depends on the device, cable, charging protocol, battery level, and temperature.\u003c\/p\u003e\u003cp\u003eDoes fast charging work with all phones and laptops?\u003c\/p\u003e\u003cp\u003eNo. Fast charging requires the device, cable, and power bank to support the same fast-charging protocol. Non-compatible devices will charge at a lower speed. Actual performance may vary depending on device, cable, temperature, and usage conditions.\u003c\/p\u003e\u003cp\u003eWhat are the dimensions and weight? Is it too heavy?\u003c\/p\u003e\u003cp\u003eIt weighs 18.8 oz (1.17 lb) and measures 3.23 x 3.19 x 2.01 in. This is normal for a 20000mAh 190W power bank. High capacity and high power need larger cells and cooling, so it feels heavier but supports laptop-level fast charging.\u003c\/p\u003e","brand":"NexaGrip","offers":[{"title":"Default Title","offer_id":68121636929778,"sku":"B0HC3BC78M","price":146.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0864\/6118\/6290\/files\/61oRbiutFEL._AC_SX679.jpg?v=1793391444","url":"https:\/\/nexagripshop.com\/products\/laptop-power-bank-20000mah-portable-charger-with-190w-total-output","provider":"NexaGrip","version":"1.0","type":"link"}
