Why is my power bank providing fewer charges than expected?

Due to approximately 35% energy dissipation at the cell and converter level during charging, the 20000mAh power bank provides about 13000mAh of usable capacity. Rated capacity: 13000mAh (5V/3A).

Why does the charging power gradually decrease while recharging?

When the power bank is recharging, its input power may gradually decrease to prevent overheating and protect the battery. For best results, use it in a cool, ventilated environment (32 – 77°F) and avoid charging other devices at the same time.

Is it allowed on airplanes?

Yes, JUOVI 65W 20000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(≤100wh≈27,027mAh).

Why does the power bank drain quickly when charging a laptop?

When charging a laptop, the power bank operates at high output which slightly reduces efficiency. Laptop batteries are also much larger than phone batteries, so the laptop’s battery percentage rises slowly, making the power bank seem to drain faster.

    My main reason for using a power bank is the backup charge that it holds and when there is a power cut or I may be away from a power source for a while, out it comes to juice up my device(s).Inside the box is the power bank, charging cable and basic user guide. The power bank is a little larger than those I have used before and has a little more weight to it, no bad thing in my eyes. Around the various sides of the bank there is a power button, display, 2 x USB-A ports and 2 x USB-C ports. The USB-C ports are combined in/out. It is a nicely designed power bank with rounded edges.Pressing the power button on, the display shows the current charge level so I started by charging this up until full. Testing the various ports out as I have both USB-A and C devices, they all connected up and were charging as expected. I do not have a device that confirms the charging speed and therefore I cannot confirm whether the 65w level was reached however often these power banks do not quite meet the stated speed.What I can say is my devices charged up quickly, my mobile phone can fast charge at 68w and comparing the charge time from this power bank to my usual charger there was not much difference. Also bear in mind then when charging multiple devices, the speed can be split between those devices.This power bank holds a great amount of charge and so if occasions occur whereby it is called upon to help out, I can be rest assured that it will provide the necessary juice to get my devices going again.

    I’m seriously impressed with this JUOVI 65W power bank. I wanted something that could charge more than just my phone, and this delivers. It charges my laptop and tablet with no issues, and still has plenty of battery left for my phone.Despite being 20,000mAh, it’s much more compact than I expected, so it’s easy to throw in my bag without adding bulk. Fast charging is legit too — my devices power up quickly, which is perfect when I’m on the go.Build quality feels solid, and it hasn’t overheated even with multiple devices plugged in. If you need a high-powered portable charger for laptops and phones, this one is absolutely worth it.

    📦 Este producto es de la marca Juovi.Se trata de una batería portátil de una gran capacidad como son sus 20.000mAh y es básicamente una tranquilidad embotellada. Con 65W de potencia, no estamos ante el típico cargador de bolsillo para el móvil; esta es una estación de energía capaz de alimentar un MacBook o un Dell XPS sin despeinarse.A continuación, detallo los pros y contras que he encontrado en este producto, justificando mi calificación de 5 estrellas.🤔 ¿LO RECOMENDARÍA? 🤔¡Mi respuesta es SÍ, ahora menciono los pro que he podido encontrar en este producto y son estos:1. Potencia real (65W) y sin duda esta es su mayor virtud. La mayoría de baterías externas se quedan en 15W o 20W, lo que apenas mantiene encendido un portátil. Con 65W, esta batería carga de verdad tu ordenador a una velocidad comparable al cargador original.2. Versatilidad de puertos (2 USB-C + 2 USB-A) y es que tener 4 puertos es un lujo. Puedes cargar tu portátil, tu teléfono, tus auriculares y hasta la tablet de un amigo al mismo tiempo. Es el fin de las peleas por el único cable disponible.3. Capacidad equilibrada (20,000mAh) donde es el “punto dulce”. Ofrece suficiente energía para cargar un móvil unas 4-5 veces o un portátil casi por completo, pero se mantiene dentro del límite legal para viajar en avión sin problemas.4. Compatibilidad total (PPS y PD) ya que el soporte para PPS es clave para los usuarios de Samsung (Carga Súper Rápida), y el PD (Power Delivery) asegura que tu iPhone o MacBook negocien la energía de forma segura y rápida.5. Seguridad inteligente al incorporar el apagado automático al terminar la carga es un detalle vital para no degradar la química de la batería de tus dispositivos valiosos.😔 ¿LE VEO ALGO NEGATIVO? 😔Aunque tiene ventajas evidentes tengo que mencionar algunas cosillas que si he visto y no me han gustado mucho:1. El peso de la potencia y es que con 20,000mAh y circuitería de 65W, no es una batería para llevar en el bolsillo del pantalón. Es un dispositivo contundente que notarás en la mochila.2. Reparto de energía en paralelo y es que ten en cuenta que si conectas 4 dispositivos a la vez, los 65W se repartirán entre todos. Para cargar tus dispositivos a máxima velocidad, lo ideal es usar solo un puerto USB-C.3. Tiempo de recarga y es que para llenar esta batería de 0 a 100%, necesitarás un cargador de pared potente (mínimo 45W o 65W). Si usas un cargador de móvil viejo, tardará una eternidad en estar lista.👉 MI CONCLUSIÓN:Resumiéndolo todo, esta powerbank de hasta 65W, es una herramienta de productividad profesional. Destaca por su capacidad de carga rápida para portátiles y su diseño apto para vuelos, lo que la convierte en el accesorio de viaje definitivo. Si buscas una batería que te permita trabajar todo el día desde una playa o un tren sin buscar enchufes.Así que por todo ello este producto se lleva mis 5 estrellas!Esta opinión es completamente personal y basada en mis gustos.Espero que te haya sido de gran utilidad mi comentario sobre este producto y GRACIAS por leer mi comentario, por ayudarme a seguir ofreciendo mis pequeños conocimientos y ayudando a las personas a decidirse por los productos, sin vuestra ayuda, esto no podría ser posible.

    Ho preso questo JUOVI 65W da 20.000mAh perché cercavo un power bank capace di reggere anche un portatile via USB‑C, non solo lo smartphone, e come concetto è proprio quello giusto: tanta potenza in un formato ancora trasportabile, con un peso che resta intorno ai 400 g. La ricarica fino a 65W si sente quando lo usi con dispositivi “affamati” (tipo laptop o tablet), e il fatto di avere più porte aiuta davvero a gestire giornata fuori casa senza portarsi dietro mille caricatori.Mi è piaciuto molto il display digitale: vedere la percentuale precisa toglie l’ansia del “quanto mi resta?”, soprattutto in viaggio o durante una giornata di lavoro lunga. In pratica lo sto usando come batteria unica per laptop + telefono + accessori, e la presenza di USB‑C e USB‑A rende tutto più flessibile con i cavi che già si hanno.Nel complesso lo consiglio a chi lavora o studia fuori e vuole un power bank potente “da produttività”, non il classico modello solo per emergenze telefoniche: è un acquisto che cambia davvero la routine quando non hai sempre una presa a portata di mano.
