Poweradd Pilot Pro 3 – Winner of Our Review
It is the Holy Grail of large-capacity portable power banks under $50. I mean a cell capacity of 30,000mAh, man, that’s huge. You can charge your iPhone 6s almost 12 times. It can charge your Samsung Galaxy S8+ nearly six times, and even then Pilot Pro3 will be left with some extra power.
Even with such massive cell capacity, it is 7.8 inches long, 5.6 inches wide and only 1.3 inches thick. It weighs nearly 680 grams and can be easily carried in your backpack.
It is made of high-quality plastic and is therefore durable, but not drop-proof. The whole body is composed of 3 different parts. Due to its considerable weight, if it falls on a rigid or rough surface, it will suffer severe damage.
There are 3 USB charging ports, and each port has a maximum output of 5V/2.1A. It uses Li-Polymer batteries that ensure longer battery life. Once charged, Pilot Pro3 can maintain its power for weeks or even months. It offers an 80% efficiency, so even though the announced capacity is 30000mAh, the actual capacity is about 24000.
It is also equipped with ID Identify technology. According to the company’s official statements, Pilot Pro3 can identify the connected devices and can then provide the best charge at high speed. It’s unique and pretty cool.
If you want to charge your devices at maximum speed, it is better to charge two phones at a time, rather than three. Poweradd Pilot Pro3 recharges just as quickly, as it uses two micro USB ports for input. Recharging time is generally 7 to 9 hours.
Due to its high power capacity, it is not allowed on different airlines. This makes it a little less portable compared to the rest of the competitors. On the safety side, it supports functions such as temperature control and protection against overload, overheating, overload, overload, discharge, short circuit, and more. It uses an A+ quality lithium-ion battery that not only reduces the total weight but also charges 500 cycles.
It is the ideal portable charger for those who are looking for a lot of energy, several charging ports that charge at a fast pace.
It is a better version of its predecessor A2 power bank. Zendure A5 is not only ultra-durable, but now it also has improved cell capacity (16750mAh). It is even allowed on various airlines, thus making it perfectly suitable for longer trips. Considering the design, it is available in black and silver color options.
According to the official sales page, Zendure A5 offers 80% efficiency. Additionally, it comes with two USB outputs, both being rated for 10.5W. Moreover, it can retain 95% of the charge capacity for about six months. The 4 LED system is useful for viewing remaining power with a 4000 mAh jump between each of them. However, there is no LED torch.
Another improvement is the Zen+ technology for power management. It doesn’t mechanically divide the output between two charging devices as 5W each. It can recognize what devices you have attached and offer the best output for charging it.
However, the negative aspect is that the Zendure A5 is big. It’s not something that you can put in your pocket. It weighs around 320 grams and comes with dimensions of 127 x 73 x 24 mm. But then you have to understand that to create such a durable product, proper quality and thickness of the plastic are required. And as a result, the thickness of the body increases, thus making it look bulky.
But the features are well worth the price. It offers pass-through charging so that you can charge it as well as your electronic devices simultaneously. The auto-on feature is another plus point, so you just plug it in without using any buttons. It is created from PC/ABS crushproof material and comes with shock-absorbing features. It also comes with a soft case to keep it all together. This includes the micro USB cable coming with the charger.
All said and done; Zendure A5 is well worth the money for those having multiple devices to charge on long journeys.

The built-in capacity of 20000 mAh in the Aukey portable charger offers enormous capacity for fully charging an iPhone 7 Plus about four times or an iPad Pro about 1.5 times. However, since the capacity of the battery is so large, it takes around 10 to 11 hours for recharging itself.

Portable chargers from Anker can easily outclass other competitors in the market, mainly because of their low price and outstanding build quality. It offers excellent quality coming from a dominant global player. The Anker PowerCore 20100 is a heavy gadget as it weighs around 12.5 ounces and offers impressive performance.

It is a monstrous portable power unit for those who need a perfect charging solution for their smartphones or other electronic gadgets while traveling.

The overall output is 4.8A. As for the input charging, it has two micro USB inputs at 5V/2.0 A for each port.

Recharging could still take around 8 hours, so you need to connect it overnight.
The portable charger comes with 4 USB output ports, and all of them can be used at the same time. It can recharge four devices at the same time while maintaining optimum efficiency.

The ports automatically detect the optimum power output needed for the device plugged in.
The EasyAcc comes with an inbuilt flashlight so that you can use it in low light conditions. 4 LED indicators reveal the amount of charge remaining. However, the total maximum output is 4.8A, so it is not practical to charge four devices at the same time. This can result in slow charging speed.

It is a high capacity charger that comes in an ultra-slim design. Vinsic portable USB charger is made up of high-quality aluminum alloy and hard plastic. It weighs around 537 grams, which means it is slightly heavy and thus it is not suitable for carrying around in your pocket.

It also offers support for an automatic on and off feature, without any buttons for starting or stopping the charging.
The power capacity is 20,000mAh, and the effective rate is about 70%, so it can quickly recharge an iPhone 5s 9 times or a Galaxy S5 about five times. It can be expected that around 14,000 mAh will be available.

Refilling the Vinsic power bank is also easy and fast with the 10W input. It utilizes a micro USB for charging itself. The required cable is offered along with the charger for free.
It does not have a soft case for carrying around and neither does it have a LED flashlight, built-in, like others in the competition. Yet, the design and its digital power display along with the auto on and off feature earn it additional brownie points.

That’s a million-dollar question or maybe not. But considering both performance and the features, I believe Poweradd Pilot Pro 3 is the best power bank you can buy. For just $39.99, you are getting such a monstrous cell capacity along with such a stylish body design. I agree it’s a bit heavy but then to gain something you also have to lose something.
