  • Protruded Side Panels
  • Not Pocket-able

There’s a range of when and why a power bank can be called a Mini power bank or at least be considered to be a small enough size and power capacity to be known as a small power bank.

There are power banks that are trying to push the envelope. Power banks that are trying to make it into the higher capacities, while still showing themselves to be in the Mini size of things.

That is why the Jackery Bar power bank is trying to prove.

Does it pass into the Mini power bank category while surpassing what it means to be a small power bank?

Power Capacity

The capacity of the Jackery Bar is the first thing that came as a surprise to me because it has a power capacity of 6,000mAh.

If you’re going to account for energy loss, then there’s not much to account for.

The energy conversion for the Bar power bank is very efficient and as a result, the power bank is capable of having an Output capacity of 5,600mAh. Yeah, you read that right, the power bank can lose about 400mAh of capacity power when a device is charging.

Fast Output Charging

There’s only a single USB charging Output power on the power bank which comes at even more of a surprise for a power bank that has relatively high capacity but we realize that the power capacity isn’t so high that two charging ports would be necessary.

The USB charging port is capable of charging at 5V/2.1A speeds.

It’s a great charging speed for a power bank of its stature because whatever device is connected to the power will be charging at or near its max speed.

The charging speed may not be at 2.4 Amps to charge an iPad at max speed but it’s got a fast enough charging speed to charge an iPad just as fast as a max speed. Speaking of charging an iPad, the power bank’s capacity although at 5,600mAh, is still quite capable of charging an iPad 3/4 of the way through.

Use it Again Rather Quickly

The Input charging speed or also known as the recharge speed of the power bank is 5V/2.0A. A good recharge that’ll have the power bank at a full capacity within 3-4 hours.

We’re astonished that the power bank is capable of so much and is barely making any compromises.

  • An output power capacity that is 5,600 and only 400mAh lower than the original power capacity
  • A fast Output charging speed at 5V/2.1A
  • A fast recharging Input speed at 5V/2.0A

Putting it all together, for a single port power bank all these features are amazing to have.


Size and Weight:

The size and weight of the power bank are what makes us wonder what category does this power bank belong in. We’ve already gone over the powering capabilities of and now it’s time to disclose the unusual design aspects of matching the power.


The Jackery Bar power bank is small. The length of the power bank is about 3.8 inches, the width is 1.8 inches, and its got a thickness of 1 inch.

So the first thing regarding the size dimensions, the power bank can fit into a pocket but it’s not going into a pocket very comfortably because of its thickness.

Other than that though, the power bank would have been great to put into a pocket, although if you’re wearing sweatpants the Jackery Bar should manage within the pocket since the pockets are looser than traditional jean pockets.

With that said, the charger is indeed a portable charger by not being too long and by not being too wide.

The charger can easily be held in a single hand since the width is very short and most important the weight of the power bank is only 5.4 ounces.

Placing the power bank into a bag is another but to be clear, you can hold this power bank in your hand and walk with it while using your smartphone. The curve of the power bank makes it a gentle experience to hold the portable charger.

Functional Components:

The functional part of the power bank is laid out in a user-friendly way. The Output and Input charging ports are on the side panel of the charger, right next to the charging ports are a LED light.

The LED light can be turned on by using the power button that’s on the side of the power bank.

Honestly, I think for power banks to have flashlights is mostly unnecessary but with this power bank, it doesn’t seem all that bad considering the power capacity.

At the top of the power bank is the 3 LED light power indicators.

Each LED light indicator symbolizes about 1,865mAh of power and if you’ve got an iPhone 6 that has a 1,810mAh power capacity then you can expect a full charge from each of those LED lights when they fully charge.

Structure and Build:

The build of the power bank is great in some areas and not great in other areas.

The center outer shell of the power bank is made of Aluminum Alloy, it’s a very common material for power banks since it’s got a strong structure but it’s very easy to scratch and smudge.

Under the Alloy shelling is a PC+ABS reinforcement layer that can take the shock from a fall. It’s a well-designed center body structure for the power bank that enables it to be well protected.

However, the side panels of the power bank could use some work. The side panels are made of plastic but that’s not the main problem, the panels being made of plastic is fine but the way they’re so outward can cause a higher risk of damage to them.

If the power bank falls, the center body is well protected, but the side panel’s outward molding and design make it very easy to be damaged.

It would be better to have the side panels depressed into the power bank so that way, the side panels are less susceptible to be damaged because then there aren’t side panels; There’s just the flat face of the charger.


Although, to end this Build section of this review on a good note. The Jackery Bar uses Panasonic Battery Cells which is a rising standard for power banks because they’re capable of losing much less energy while charging a device.

That’s why the power bank is capable of maintaining near its power capacity.


The reliability of the Jackery Bar power bank is compatible with those seeking nearly any charging experience.

Altogether, we think that the minimum kind of experience that you’ll get from this power bank is “Good”. If you’re searching for a power bank that’s going to charge multiple devices at once, this isn’t it, even with the capacity.

Jackery Bar is a heavily reliable Mini power bank that’s going to bring speed and longevity to whatever device that you charge with it.

This especially goes for smartphones and as a result, the Bar power bank is can very well last on a full single charge for days before needing to be recharged.

Our estimates before the power bank needed to be recharged to full capacity were about 3 days.

The portability of the power bank is outstanding considering its capacity, although you won’t be easily fitting it into a pocket the power bank is very capable of being held in a single hand and used.

Putting it into a bag is an option but it’s not necessary since the charger is indeed portable and very usable.

The capacity 6,000mAh is only cut short by 400mAh and as a result, the power capacity of the power bank is still very high at 5,600 and is capable of charging many smartphones 3 times over.

Output and Input charging speeds are speedsters with 2.0 Amps charging with this highly portable power bank.


Portability isn’t a problem when it comes to the Jackery Bar. The dimensions are very short and the weight is light, putting those two facets of the power bank together make it so that it can be carried in a single hand and used. Fitting it into a pocket is very feasible but still possible if you’ve got loose pockets.

Functional features are placed appropriately and even a LED flashlight holds logic with this power bank. One main flaw though is that the design leaks over into Build flaws for the power bank.


Center body make of Aluminum Ally is tough, still open to scratches and smudges. An under shell can withstand shock from falls and altogether the center body of the power bank is sold.

However, the plastic side panels are placed poorly and should be depressed into the power bank so they’re more protected.


The reliability of the power bank is near the top tier. Don’t get this power bank if you’re looking to charge multiple devices at once.

Other than that, the power bank is very reliable with its ability to charge at max speed, be used for days without needing to be recharged, and highly portable design.
