A good external battery can save you from having to take a charger with you all the time, but you still have to choose it well: you have to take into account its energy storage capacity, its connectors, its charging speed or even her size.

Xiaomi Mi Power Bank 3 external battery, the all-rounder

The Xiaomi Mi Power Bank 3 external battery is mainly intended for people who want to charge several devices at the same time, and who need a large source of energy.

Indeed, it has a capacity of 10,000 mAh, which can fully charge between 3 and 4 times most smartphones on the market.

You can fully charge your touch pad up to 3 times.

The presence of three output ports makes it possible to charge up to three devices at the same time.

The battery is recharged with a USB-C cable.

External battery Anker PowerCore, the high capacity

With the Anker PowerCore, you can recharge your smartphone up to 6 times, since this external battery has a capacity of 26,800 mAh.

It's just huge, and that partly explains why its size is similar to that of a large smartphone.

The presence of three USB ports allows you to connect up to three devices at the same time, with USB-C, USB or micro-USB connectors.

The battery recharges in 6:30 using two micro-USB ports of 20 Watts: a relative slowness, which is explained by the high capacity of this imposing model.

Samsung external battery, wired and wireless

With a capacity of 10,000 mAh, the Samsung EB-U3300XJEGEU power bank can allow you to fully charge two smartphones once each, or one smartphone twice.

If you decide to plug in a device, you benefit from a power of 25W.

But the other advantage of this model is that it has a 7.5W induction charging system.

You can simply lay a compatible smartphone on the battery to charge it wirelessly, which is a big plus.

However, this model only has two USB-C connectors.

External battery Belkin, the balanced

With a total capacity of 10,000 mAh and the presence of a USB port and a USB-C port, this Belkin smartphone power bank can allow you to charge two devices at the same time.

A classic terminal can be recharged up to four times with this very easy-to-use model, with a design that strikes a good balance between size and functionality.

Four light indicators are present on the side of the device: they allow you to have an immediate overview of the remaining charge capacity.

A practical backup battery, which is also quick to recharge.

Apple MagSafe external battery, for the iPhone

Compatible with all iPhones from iPhone 12, the Apple MagSafe external battery allows you to charge your smartphone by magnetically positioning it on the accessory.

That's the great thing about MagSafe: you don't need a cable and the two devices stay glued together.

Wireless charging reaches 15W and it is possible to use a cable for a 20W charge.

If this battery benefits from Apple's design, we can regret that its capacity is limited to 1460 mAh, which is not enough to fully charge an iPhone.

How to choose your external battery?

One of the most important points regarding the choice of an external battery is none other than its capacity: the larger it is, the longer you can charge your smartphone.

Try to opt for a model with a capacity of at least 10,000 mAh.

Then, make sure that the connectors on the battery correspond to those of your devices: if you only have USB-C cables, you must choose a suitable model.

Many batteries have different types of connectors.

Finally, the size is also important: most of the time, the more an external battery has a large capacity, the larger and heavier it is.

If you plan to carry your battery with you in a pocket, it must be comfortable to transport.

Finally, the price must be taken into consideration:

Tips for maintaining your external battery

When you receive your battery, take the time to fully charge it before using it: this allows a good calibration of its autonomy.

In general, it is strongly discouraged to let an external smartphone battery completely discharge, as such a practice can have a significant impact on its lifespan.

Furthermore, it is also not recommended to use the battery to recharge a device while it is itself recharging: this can, once again, affect its lifespan.

When you are not using your power bank, it is best to turn it off completely.

However, it is a fact, not all booster battery models have an on/off button.

When this is the case, it is better to use it, once again to ensure long-lasting use of your device.
