The largest external batteries have a minimum of 10,000 mAh, have the Quick Charge function and allow a device to be charged at least 2 times fully.

We all suffered from the sudden and overwhelming horror of a dead phone. The accusatory aspect and the gloomy criticisms of family and friends.

Feeling panicked as you realize your phone alarm didn't go off because you forgot to connect your phone last night. Why do our smartphones have to die?

The Best External Batteries In 2021

If you want to charge something fast, then the power of Anker PowerCore is hard to beat. This long, thin battery has 20,100mAh, enough to charge your mobile phone at least three or four times, maybe more depending on the model. You can also charge an iPad or even a small laptop, although we recommend that you check compatibility before you buy.

It has an elegant, subtle design, with the usual power button on the side and 4 blue LEDs to display the remaining power. There are two ports: A standard USB-A with a rated power of 5V / 2A and a USB-C PD (Power Delivery) output that can deliver up to 24W. You might think it looks a little expensive, but you also have a 30W wall charger in the box, along with a USB-C to USB-C cable, a USB-A to Micro USB cable, and a carrying bag. It's all you need to charge your devices quickly and on the go.

I tried the external battery with a Pixel 3 and found that it is capable of fast charging. The built-in wall charger can also quickly charge an iPhone XR or an iPad Pro . When the power battery runs out, you can fully charge it in just four hours with the supplied charger and USB-C cable. If you are looking for a battery with quick charge functionality, then this package is for you.

QI Powerbank – a wireless / wireless battery with the Quick Charge 3.0 option has a square, unique design and is great for those gadgets that support fast charging. The Power Bank can quickly charge a smartphone with 80% quick charge in 35 minutes, saving a lot of time.

The battery itself supports two types of USB ports (Micro and Type C) for recharging, 3 USB output ports (USB C + QC3.0 + USB A) that can automatically detect the compatibility of the device being charged, adjusting the charging current to get the fastest upload.

As a disadvantage, the battery is quite heavy for this size, but given the low price, Qi Powerbank is a very good option for wireless charging.

Anker is a trusted name when it comes to external and portable battery chargers, and this special option demonstrates why. Compared to the smaller (and cheaper) version mentioned above, the 26,800mAh version from Anker is more than enough to fully recharge your smartphone several times, as well as the rest of the gadgets.

The power battery comes with three USB ports, including a 30W USB-C port to allow you to charge a MacBook or Nintendo Switch. Moreover, Powercore benefits from protection against short circuits, overloads, as well as current and voltage spikes.

The portable charger also comes with a 30W USB-C wall charger.

RAVPower 10050 mAh is the perfect choice for a battery prone to difficult conditions. Guaranteed IP66, RAVPower is both waterproof and dust and shock resistant, making it the best choice for those looking for a durable but pleasant looking external battery.

The Powerbank has built-in I Smart Technology, which distinguishes the connected mobile phone model and transmits the ideal charging current for your gadget. RAVPower comes with two USB ports, 2.4A and 1A and a capacity of 10050 mAh, which is suitable for charging an iPhone 8 more than five times. Internal protection against short circuits and overheating will protect both your charged gadget and the battery itself.

Mi Power Bank 2S has a minimalist design, made of machined aluminum. It measures 5.1 by 2.9 by 0.5 inches, similar to the average size of a smartphone. The top and bottom of the battery are covered with plastic. On the top edge, a Reset button allows you to start and stop charging, although the battery automatically detects most devices. Four white LEDs on the right show the charging status.

The USB-C port is for input only and supports fast charging. The USB-A output supports Qualcomm QuickCharge 2.0, which means it is capable of charging at 5V / 2A, 9V / 2A and 12V / 1.5A. When I tested it with the LG V30 +, it was successfully charged at 9V / 2A. This is an older standard than Fast Charge 3.0 on PowerCore which can dynamically vary the voltage up to 20V for faster charging speeds.

According to Xiaomi, the 10,000mAh Mi Power Bank maintains a conversion rate of 93%, minimizing the power you lose when charging devices. This proved to be true during testing.

Xiaomi Mi Power Bank has almost everything you can ask for from an external battery. Its slim and elegant design is complemented by a large capacity, excellent energy efficiency and fast charging. The battery specifications as well as the small size offer excellent value for the price, remaining the preferred option of our publishers.

ASUS ZenPower – Cheap / Low Budget

The Best External Batteries In 2021 5

At first glance, the Asus ZenPower brings quite a bit with Xiaomi's external batteries. However, there are several color variants, including the gold and silver variant. The size is about that of a credit card in length and width, however the powerbank is quite thick for its power of 10050mAh.

To add more color to the Asus Zenpower , Asus has introduced rubber cover sets that definitely add better grip. The rubber used is of very good quality, but unfortunately they must be purchased separately. The 4 white LEDs that show the percentage of charge represent each 25%, so you can easily monitor the condition of the battery.

The 10,000 mAh capacity makes the ASUS ZenPower a medium-sized battery capable of fully recharging a smartphone twice. For us, this is a very good option given the low price below 100 RON.
