Small portable chargers are a great way to carry portable power with you. It’s actually best to choose a small size for a power bank if you plan on using the charger and your device at the same time.

However, the smaller the portable charger, the less power capacity it will have and the charging tech that goes into it is usually less advance.

Although, that isn’t always true. Instead, there are some chargers that are able to keep their “Mini” size and still deliver an equal charging experience to that of a high capacity power bank. Just without the insanely high capacity.

That’s what this RAVPower 6,700mAh portable charger is able to accomplish. It’s a small sized charger that’s able to deliver a full-fledged charging experience with not so many flaws.

Power Capacity:

So the initial capacity of the power bank is 6,700mAh and it’s pretty good but it’s important to remember that’s not the actual power that you’re receiving.

Since the charger is capable of charging at a max speed through its single USB charging port of 5V/2.4A, it’s going to depend on what speed the device that’s connected to the charger is going at.

However, the average amount of capacity that you’ll most likely receive assuming that you’re charging a smartphone with this power bank; you’re most likely going to receive an Output capacity of 5,000mAh.

It’s actually still a lot of power capacity, but the more Amp current (Charging speed) that is transferred, the more heat that is generated and results in more power being lost.

So if you’re charging a tablet like an iPad, you can expect a lower Output capacity because iPads have a max charging speed of 5V/2.4A.

Overall, you can expect this mini power bank to fully charge most smartphones two times and some can even charge more if their battery capacities are small. For a tablet, however, you can only hope to get 3/4 of a charge.

Output Charging: 5V/2.4A

A Very Fast Charging Speed for a Mini Power Bank

There’s only 1 USB Output port that is capable of delivering a max standard charging speed of 5V/2.4A. This does not feature Quick Charge, so it won’t charge your Quick Charge compatible devices at their max speeds.

However, for any other devices, the charger will be able to deliver its max charging speed. As we mentioned earlier, this power bank can charge a tablet at its max speeds of 2.4A, which exactly matches the power bank’s capabilities.

Ultimately, if you’re worried about small power banks providing too little power and charging your smartphone slowly; there’s no need for that here. It’s surprising, though, not many small portable chargers are able to deliver anything over 2A but here it is.

Recharge: 5V/2.0A

The RAVPower portable charger is recharged through a Micro-USB port, with a max recharge speed of 5V/2.0A.

With that said, we said “Max Speed” because the only way to recharge at a speed of 2.0A is to use a 2 Amp wall charger. If you use a wall charger with lower speeds, then you’re going to experience slower recharging.

At max recharge speed, you can expect the power bank to be recharged within 4-5 hours.

The power capabilities of the power bank are really good, sure the power capacity is lower than the stated but this kind of case is usual for many portable chargers. It won’t last you a week before needing to recharge it, but it can last you a day or two.

Size and Weight:

The best way to describe this power bank is that it’s palm-sized. This means that the charger is a perfect size to fit into the palm of your hand because that’s what the dimensions and weight match up to.

Take the Power Bank Anywhere

The small portable charger has a length of 3.5 inches, a width of 1.6 inches and a thickness of 1 inch. It weighs very lightweight at only 4 ounces.pic-1

So the charger can be held in a single hand and be used to charge your smartphone while it’s being used. However, this power bank is going to be very difficult to fit into your pocket because of the thickness of 1 inch.

Is it possible to fit it into your pocket? Sure, but will it be comfortable to fit into your pocket? That’s a pretty big NO. It’s a small charger but not to the point of being able to go into your pocket easily.

Functional Components:

On the design side of where the functional components are, the power bank is very easy to use. The USB Output and Micro-USB Input port are on a single side.

The power button is on the long side of the charger and there are 4 LED power indicators on top of the power bank. The power button is barely used because the charger is able to automatically detect the device that’s connected to it and begin charging.

If there aren’t devices connected to the power bank, then it automatically shuts off. So you’ll only be using the power button to check how much capacity is left on the charger most of the times.

Build

Structure and Material:

One of the most prominent things that you’ll notice about this power bank is that it’s built very well. With only two parts making the power bank complete, the charger holds strong.

The material is plastic but it’s still very sturdy and ultimately it’s the compactness is what makes this charger so strong and why it’s able to be used every day; since it can take everyday challenges.

Also, the casing is made of Thermoplastic which is resistant to fire, and plenty of RAVPower’s power banks feature the same kind of build quality such as their 22,000mAh charger.

Tech:

On the inside is quite a bit of safety tech that will keep your charging experience going smoothly. With Over Charging Protection and Short-Circuit protection, your device will be safe.

Reliability

Just like a lot of these small power banks, these are most reliable if you’re using them to charge a smartphone.

This is because if you’re using the power bank to only charge your smartphone, you can take the power bank with you so it’s very portable.

Also, the amount of the power capacity delivered to your smartphone will be more worthwhile as it can charge it 2 times or more. The charging speed of the charger is great because it can reach a max speed of 5V/2.4A and that’s enough power to charge a tablet at its max speed.

Speaking of the tablet, that’s where the portable charger is at its most unreliable state. Sure, you can charge a tablet like an iPad at its max speed but you can’t charge iPad to its full capacity since Output Capacity will be lower than the original power capacity.

Also, you can’t really use an iPad with one hand while you’re walking around with this charger.

These are trivial things to take into account but it’s important to know that this portable charger, being small, is meant to be used in a highly nimble way.

Summary:

Power

With its max charging Output of 2.4A, you can expect this power bank to charge most devices connected to it at its max speed. The power capacity is cut short due to power lost during charging, so you can expect this to supply about 5,000mAh of power.

With that said, it puts this power bank into the category to be used mainly for smartphones. Tablets, on the other hand, won’t charge all the way but will receive their max charging speed.

Design

It’s a portable charger that’s best to fit into the palm of your hand, because of its small dimensions and lightweight. The power bank may be able to fit into a pocket but it’s a bit of a stretch since the thickness is that it’s one inch.

The components are in easy to find places, and you’ll rarely use the power button since charger automatically starts charging when a device is connected to it and it turns off when nothing is connected to it.

Build

The build Is very strong with just two pieces connecting together to make the power bank whole. The material it’s made of is Thermoplastic that’s fire-resistant. On the inside is plenty of safety tech to keep your devices safe.

Reliability

It’s a most reliable charger when you’re using it with a smartphone and are on the go. The lightweight, small size, fast charging and enough power capacity for smartphones all come together for great powerful portable charging.

You won’t get the best experience if you’re only using it with a tablet, but it’ll still charge the tablet at its max speed. So that’s good.

Specs of the RAVPower 6,700mAh Power Bank:

  • Capacity:            Advertised: 6,700mAh             Output Capacity: 5,000mAh
  • Output: 5V/2.4A
  • Input: 5V/2.0A via Micro USB Input
  • LED Power Indicators: 4 LED Power Capacity Indicators
  • Size: 3.5 x 1.6 x 1 inches
  • Weight: 4.2 Ounces

Conclusion:

Few mini power banks are able to provide an output of 5V/2.4A, the max standard charging speed. It’s actually a little bit unnecessary considering that the small charger is mainly to be used by smartphones.

But that’s okay since the charger will be able to charge any smartphone (that not Quick Charge compatible) at its max charging speed.

The same goes for tablets because the max charging speed for them is 5V/2.4A; but alas it doesn’t make much sense to use a tablet with this power bank since it won’t fully charge it.

Moreover, this portable charger is meant to supply the featherweight, fast charging, and enough power capacity for on the go adventure with your smartphone.
