Power banks that use built-in charging cables are among the most useful kinds of power banks because you always have the charging cable that you use the most with you.

Also, what makes these power banks even more useful is that some of them have USB Output charging ports and that means that if you want to charge devices that aren’t compatible with the Built-In charging cable, then you can use your charging cable to charge another device.

With that said, power banks that use built-in charging cables are great if you want to always have the possibility of charging the device that you always use. This is the OLALA C2-6,000mAh power bank that uses a built-in Lightning charging cable.

Power

Power Capacity:

The power capacity of the OLALA C2 power banks starts at 6,000mAh and it has a normal conversion rate that most power banks have.

As a result, it has a conversion rate of about 70% because for one reason is that the power bank uses Lithium Polymer batteries and there are inefficiencies of transferring power through charging cables, which is why you’ll have an Output power capacity of 4,200mAh that you can use.

So most of the time, it’s going to make sense to use smartphones with the OLALA power bank because it’ll be able to charge most smartphones like iPhones about 2 times to their full power capacities.

Charging tablets doesn’t seem like the best option because even when you’re using the entire power capacity to charge a tablet-like iPad Mini it’ll cover about 60% of the way through. Charging Full-Sized tablets will result in about 40% of a charge.

Output Charging:

The power bank has 2 main charging methods. Of course, there’s the main reason why you’re getting the power bank in the first place which is to charge it with the Built-in Lightning charging cable. Then there’s the USB charging port that can be used by any charging cable.

The Lightning charging cable that’s built into the power bank is only capable of Outputting 5V/1.0A charging speed. The USB charging port that can be used to charge any device with the charging cable that you use can Output 5V/2.4A, which is a Max Standard charging speed.

We did find it a disappointment that the Lightning cable wasn’t able to provide the 2.4A charging speed because if that were the case, then an iPad or iPhone would be able to charge at their max charging speeds with the reliable built-in charging cable.

However, if you want to charge your Apple devices at their max charging speeds, then you’d have to use a separate Lightning charging cable and use the USB port.

For the most part, it’s nice that the power bank has a Built-In charging cable but the charging speed of it is slow.

Input Charging:

The power bank can be recharged at a charging speed of 5V/2.0A and as long as you’re using a 2 Amp wall charger to recharge the portable charger, it’ll be able to recharge within 5-6 hours.

Design

Size and Weight:

It’s a very portable and usable power bank and that’s one of the major reasons why you should buy it.

This is because the OLALA power bank has a length of 5 inches, a width of 2.5 inches, and a thickness of 0.6 inches. So it’s a very small power bank that can fit into the palm of your hand easily and it can even fit into your pocket too.

Not just because the power bank is small but also because it only weighs 5.1 ounces making it very lightweight too.

Functional Components:

The power bank is as easy to use as its ease of portability.

On the short side is where you’ll find the built-in Lightning charging cable that can be pulled out from the power bank itself and it’s about 2 inches long, as well as the Micro-USB input port and the USB Output port, which are on the same side.

On the long side of is where there’s the power button. On top of the power bank is 4 Blue LED power capacity indicators.

To start charging you have to press the power button and charging stops when either the device that you’re charging is at its full power or when there aren’t any devices connected to the power bank to charge.

Build

Structure and Material:

It’s quite a durable power bank but just don’t go dropping it on hard ground.

The top and bottom portions of the charger are made of plastic and the center lining is made of Aluminum.

Tech:

OLALA has stated that the power bank has a 7 safety layer protection system to make sure that nothing goes wrong when you’re charging either 1 or 2 devices at the same time. With that said, the charger does have the occasional heating up issues.

Reliability

For the most part, those that use either an iPhone or iPad are going to find this power bank the most reliable because in a built-in Lightning charging cable that you’ll always have handy anytime that you have the power bank around.

Those that don’t even own Apple devices should probably sit this one out because you’ll have a completely useless part of the power bank at all times.

Design:

It’s really small and very light which makes it very easy to carry around.

Build:

The not strongest build but it’s good for daily use. On the inside, there are lots of safety protections but the portable charger does tend to heat up at times.
