CUKTECH 15 SE Power Bank 20000mAh 65W Laptop Charger, 3-Port USB C Portable Charger, PD 3.0 Fast Charging External Battery Pack for iPhone 16/15/14 Series, Samsung, MacBook, Dell, Steam Deck, and More

The Best Travel PoweAfter ordering and testing several highly-rated power banks, this CUKTECH 15 SE 20,000 mAh Power Bank is hands-down the best of the bunch for my needs—and I’m very picky. What I was looking for: • ✅ Airplane safe – At 20,000mah, it hits the maximum battery size for the FAA limit and is totally fine for carry-on. No more worries at security or the gate. • ✅ True pass-through charging on every port – This was a dealbreaker for me, and most power banks I tried only allow it on one port, maybe. It also significantly slowed down the charge and the output. With this one, I can charge the battery and still draw power from all ports at once - all at full speed. That makes a huge difference when traveling and trying to keep everything topped up. • ✅ Fully powers my MacBook Pro – I’ve run it as my main power source while working remotely, and it keeps up without a hitch. • ✅ Daisy chains like a champ – I’ve successfully used it in a multi-device setup: powering my MacBook, charging an external battery, running an iPad and phone—all through different ports—without issue. This thing handles complex loads like a pro. Build quality is solid, charging speeds are fast (tested and hit up to 65 W per USB‑C port), and the digital battery display is a nice touch, although i wish it showed wattage not just percentage. The only things I wish it had: a built-in AC wall plug and built-in cables. Those would make it absolutely perfect. But even without them, this is still the charger I’m keeping and traveling with. Everything else I ordered is going back. If you’re looking for a compact, carry-on-compliant, high-output power bank that just works—and lets you charge multiple devices and itself at the same time at a reasonable price—this is it. Next comparable thing is the UGREEN Nexode but it's twice the price.

So far so good. Comparable to my old 20k chargers in weight and dimensions, but charges very quickly. The only downside so far is the low power charging toggle for my dac or my earbuds. For a literally quick top up, its doing great so far. The name is odd, but luckily I haven't had too many people take notice enough to give me 20 questions. 2 USB-C's and a USB A are great for flexibility. The higher watt model was also tempting, but this is a good Goldilocks zone.

It's a solid battery bank. I've used it to charge up my Macbook Pro. No fancy Bluetooth features that you need an app for. This is just a basic battery bank with a display to show you what percentage of charge it holds. I think it's about as heavy as a regular soda can, and can fit easily into a carry on bag.

I use this with a barrel adapter to power my Dell laptop. The 65w output seems to work great & gives me hours of extra power for my laptop & phone. I love that it has a display for the charge percentage. It charges my phone fast, which is great. Perfect size for travel. Would definitely recommend!

At a price of ~$40, this is one of the best power banks on the market in terms of price-performance ratio. While it has less power than the regular Cuktech 15 (not available on Amazon currently), it offers significantly more usable capacity and is usually considerably cheaper. It features a wide PPS range and supports many charging protocols. And it can sustain 85W max output until the battery is depleted. Easy to recommend.

Battery capacity has dropped of significantly after just a few weeks of use. It now only lasts my laptop about 3 hours from a full charge. Based on the advertised mAh it should last 8 hours or more. -- Update: they gave me a 30% refund and explained more about the product which was very kind

I wasn't sure how well this charger would work since the price was so reasonable, but it's actually amazing. It charges my devices so fast and is big enough to charge my phone multiple times over. It comes with a bag and a short usb-c to usb-c cable. Its pretty heavy, but that's to be expected with the size.

Great Power bank for macbooks. On the heavier side and has lot of juice. Good for long travels. Was able to charge multiple devices.

High quality item, powerful, & versatile. Very handy size, not heavy considering the power. Charges my TAB S9 Ultra very fast & my lower amp devices (1A) too which means its circuitry is spot on.

Vraiment c'est un super produit, robuste et de bonne facture, avec un bon rapport qualité. L'autonomie de la batterie est très bien il faut compter environ 5-10% pour un charge rapide de 30-40%. Je vous la conseille sans hésiter

Good product. Charging is fast and reliable. I really like that it includes a cable and a pouch bag.

Bastante útil

Tras probar varias baterías externas de alta capacidad, esta CUKTECH 15 SE me ha sorprendido gratamente por su equilibrio entre tamaño y potencia de salida. No es solo una "power bank" para el móvil; es una verdadera estación de carga capaz de mantener con vida un ordenador portátil en cualquier lugar. Rendimiento de carga (65W): El punto más fuerte es su salida USB-C de 65W con protocolo Power Delivery (PD). La he probado con un [menciona tu dispositivo, ej. MacBook Air, Dell XPS o iPhone 15 Pro] y la velocidad de carga es prácticamente idéntica a la del cargador de pared original. Es capaz de cargar un portátil mientras lo usas sin que el nivel de batería baje, algo que muy pocas baterías de este tamaño consiguen de forma estable. Capacidad y Eficiencia (20000mAh): Con 20.000 mAh, ofrece la capacidad ideal para viajes largos. En mis pruebas, me ha permitido cargar completamente un smartphone de alta gama unas [X] veces o darle una carga casi completa a un portátil de 13 pulgadas. Se nota que las celdas internas son de calidad, ya que la pérdida de energía por calor es mínima durante el proceso de carga rápida. Diseño y Pantalla Digital: - Pantalla: A diferencia de las baterías que solo usan 4 LEDs, esta incluye una pantalla digital que muestra el porcentaje exacto de energía restante. Es muy precisa y evita quedarte sin batería por sorpresa. - Construcción: El acabado es robusto y tiene un diseño moderno y minimalista. A pesar de su capacidad, el formato es "slim" (alargado), lo que facilita mucho meterla en los compartimentos estrechos de una mochila. - Puertos: Contar con 3 puertos permite cargar el portátil, el móvil y unos auriculares simultáneamente, aunque hay que recordar que la potencia total se reparte entre ellos cuando se usan a la vez. Carga de la propia batería: Un detalle importante es que la batería también admite carga rápida de entrada. Usando un cargador potente, se rellena en mucho menos tiempo que las baterías convencionales de esta capacidad, lo cual es vital si tienes poco tiempo antes de salir de viaje. Al recibirlo viene con una pequeña funda para tenerla guardada y que no sufra ningun daño al transportarla, un manual de instrucciones de uso y un pequeño cable tipo-c de carga rapida de 65W para poder cargar y descargar la bateria en cualquier momento
