Battery life is a common problem for users of smartphones and other electronic devices. There’s a solution to this need: the 20,000 mAh power bank. These portable energy storage devices allow you to recharge your devices anytime, anywhere, giving you unrivalled autonomy and peace of mind.
But how do these batteries work? What are their advantages, and how do you choose the one that best suits your needs? In this article, we guide you through the world of 20,000 mAh external batteries.
What is a 20000 mAh external battery?
The 20000 mAh power bank is a portable energy storage device for recharging your electronic devices. The term “mAh”, which stands for milliampere-hour, is a measure of a battery’s energy capacity.
The higher the value, the more energy the battery can store and therefore recharge your devices. For example, a 20,000 mAh power bank can fully recharge a smartphone with a capacity of 4,000 mAh around five times.
One of the main advantages of the 20000 mAh external battery is its high energy storage capacity. It offers longer autonomy than other types of external battery.
What’s more, thanks to its capacity, it can recharge several devices at the same time, making it ideal for travel or situations where you don’t have access to an electrical socket.
How do you choose a 20000 mAh power bank ?
Choosing a 20000 mAh external battery may seem complicated, but there are a few key factors to consider. First of all, the battery capacity is essential. A capacity of 20000 mAh offers excellent autonomy and means you can recharge your devices several times.
However, you also need to consider compatibility with your devices. Some external battery models may not be compatible with certain devices. So always check this information before you buy.
Secondly, charging speed is another factor to consider. Some external batteries offer fast charging, which can be very handy when you need to recharge your devices quickly.
Finally, the weight and size of the battery are also important. A 20,000 mAh power bank may be a little heavier and larger than other external batteries of lower capacity, but it offers better autonomy.
Introducing a 20000 mAh USB-C power bank with Power Delivery function
In the vast world of external batteries, one in particular stands out: the USB-C 20000mAh Power bank with 22.5W Power Delivery function.
This new-generation battery is capable of recharging your phone to over 55% in just 30 minutes, thanks to its Power Delivery function. Once fully charged, it can recharge your smartphone up to four times, a testament to its remarkable capacity.
In addition to its performance, this 20,000 mAh power bank boasts a secure design and high-quality construction, guaranteeing longevity and reliability. So not only is it a powerful companion for your devices, it’s also a long-lasting investment.
The USB-C 20000mAh Powerbank has two output ports, one USB-A and one USB-C, and can deliver up to 3A with Power Delivery 3 and Quick Charge 3. It also comes with a 30cm USB-A cable for easy connectivity.
Another notable feature of this external battery is its transfer charging capability, so you can charge it from the sun while simultaneously charging your laptop. It has four charge indicators showing levels from 25 to 100%, so you can easily monitor its energy level.
Advantages and disadvantages of a 20,000 mAh external battery
A 20,000 mAh external battery has a number of advantages. Firstly, it has a large charging capacity. It can charge a smartphone or tablet several times, which is ideal for long journeys or periods without access to a power source.
Secondly, some batteries of this capacity can charge several devices at once, which can be very useful if you have several devices to charge.
However, a 20,000 mAh external battery can also have a few drawbacks. Because of its large capacity, it can be heavier and bulkier than other external battery models.
What’s more, the battery itself may take longer to charge. So it’s important to take these factors into account when choosing an external battery.
Maintenance and lifespan of a 20000 mAh external battery
Like any other electronic device, a 20000 mAh external battery requires maintenance to prolong its life. Avoid leaving it on charge once it’s full, as this can damage its long-term energy storage capacity. It is also advisable to recharge it every three months if it is not in use, to prevent it losing its capacity.
In general, the life of a 20,000 mAh external battery depends on how it is used. With normal use, it can last between 3 and 5 years. However, this can vary depending on the make and model of the battery.

Je suis partie dans le désert du Sahara avec le Kit Randonneur. Ce n'est pas mon premier trek, avant je partais avec 2/3 batteries externes pour pouvoir continuer à faire mes photos avec mon téléphone. Cette année, avec Kit Randonneur, c'était parfait, le panneau était constamment au soleil donc la batterie à rechargé très rapidement et une fois posée dans les bivouacs, je branchais direct mon téléphone au panneau pour garder la batterie pour la nuit. Un super kit qui fait vraiment bien le job, super qualité, léger, passe-partout (dans un sac à dos, une valise etc...) et résistant ! Un super produit que je recommande et que je vais continuer à prendre avec moi :)
Étonnée de la rapidité de la livraison !
On sent à peine les 300g. Acheté pour un trek dans les Alpes. J'ai fait un petit test avec une batterie solaire, ça l'a directement mis en charge. A voir après plusieurs jours en pleine nature !
Je completerai mon avis de ce fait.
Maj 19 août : 7h en plein soleil : 50% de charge sur batterie externe. Charge distribuée ensuite efficacement. Je suis plus que ravie, merci !
Expédition rapide, j’ai acheté un PT Flap 11 que nous allons utiliser en Août sur la traversée des Alpes ( 5 semaines) . Très bonne qualité de fabrication au visuel. Premiers tests en statique concluants et correspondant aux spécifications. Je ferais un retour mi septembre à nôtre retour ✌️
très bon produit
Le panneau solaire marche bien, la batterie a eu quelques soucis au bout de quelques mois d’utilisation : mail de contact et aussitôt une batterie neuve a été expédiée.
Petit bémol sur la procédure de SAV qui n’est pas explicite sur le site
Commande passée sans soucis. Matériel conforme . Au top 👍
