Perfect for backpacks, notably large belt bags, or luggage. NOT great for grab-and-go, smaller belt bags, or pockets.
Get this if you need the size (awesome for iPad and phones), or get Anker's smaller version if you want to be portable (10,000mAh is still quite a bit for 2 people within a day).
Using this for traveling was incredibly reassuring and pleasant, but it was notably heavy for walking around without a full backpack or satchel. If I were to do it again I would have got a 10,000mAh version, each of our phones are around 5000mAh so it is still enough for 2 full charges a day, or one per person in a couple without the bulk. Pair it with a long cord and a backpack and it would be fine as well!
Love this!

Ya sea explorando o simplemente descansando junto a la piscina, nunca tuve que preocuparme por quedarme sin batería. ¡Fue un cambio total de juego!
La velocidad de carga también es impresionante. Con hasta 20 W a través de 3 puertos USB, pude cargar rápidamente mi teléfono, cámara e incluso mi tableta cuando lo necesitaba.
Además, tener la tranquilidad de saber que cuenta con funciones de seguridad integradas no tiene precio. Pude disfrutar de mis vacaciones sin preocupaciones.
En resumen, fue una parte esencial de mi viaje y lo recomiendo encarecidamente a cualquiera que esté planeando su próxima aventura.
Incluido en la caja: Cargador de batería Anker 335 (PowerCore 20K), cable USB-A a USB-C, guía de bienvenida, garantía de 18 meses y servicio de atención al cliente amable.
