  • Small form factor that can be placed into a pocket

Cons

  • Does not feature Power Delivery

Power banks have come a long way in a short amount of time. There are now power banks that have 10,000mAh power capacities, and yet they have a form factor of a power bank that has a 3,000mAh power capacity.

In this review, we’re going to be taking a look at one of Jackery’s rather new power bank on the market. This power bank of their acts as a wall charger and a power bank, as it makes use of a built-in AC adapter, and it also has batteries, too, so you can take it anywhere you go.

One of the most notable parts of this power banks is that it makes use of a USB-C port, something that not many 2-in-1 power banks makes use of.

Power

Power Capacity:

The initial power capacity of this Jackery power bank is 6,700mAh. Since this power bank doesn’t make use of any fast charging tech such as Power Delivery or Quick Charge, the conversion rate of the power capacity during charging is going to be average. Let’s calculate that.

3.7 x 6,700 = 24,790 / 5 = 4,958

The average output capacity that you’ll receive from this Jackery power bank will be about 5,000mAh. This much power is able to charge most smartphones to full power at least once. Most smartphones on the market have a 3,000mAh battery sizes such as the Samsung Galaxy S8 and S9.

However, even the regular 3,000mAh battery size is now being surpassed, with the current Galaxy S10 using a 3,400mAh battery. While the S10 Plus actually makes use of an even larger 4,100mAh battery.

So a 5,000mAh output capacity for some smartphones can truly only mean a single full charge and just a little more power capacity to spare after that.

As for charging tablets, well, this power bank can be a good option, but it likely won’t charge a tablet to its full power, as tablets usually have upwards of a 5,000mAh battery size.

Output Charging:

Standard charging for a Galaxy S8

There are two ports to use.

One is a USB-A port and the other is a standard USB-C port.

Even though the USB-A port on this power bank is colored Orange, it does not feature Quick Charge. The USB-A port is a standard port that has a 5V/2.4A (12W) charging speed.

So it does have fast standard charging, but don’t expect it to fast charge your Android smartphone.

 

However, for fast charging, the USB-C port on this power bank can be more helpful as it has a 15W (3 Amp) charging speed. If you own a USB-C Android smartphone, then using the USB-C port on this power bank with a USB-C to USB-C Cable is going to prove a lot faster than the USB-A port.

The one downside with charging with this power bank is that if you’re using both of the ports at the same time, then the max output of the power bank defaults to 15W. As a result, you can’t use the full power of the two ports at the same time.

Input Charging:

There is only one way to recharge this power bank and that would be from plugging it into an AC outlet with its built-in AC adapter.

However, having the ability to use the USB-C port to recharge the power bank can also be quite useful, too, but this power bank only has the USB-C port as an output port.

Of course, you can still charge from the power bank when it’s recharging from an AC outlet.

Design

Size and Weight:

The size of this power bank is very small and you’re going to have no problems taking it anywhere that you want. The charger has a length of 3.1 inches, a width of 2.9 inches and a thickness of 1.1 inches.

The weight of the power bank is 6.2 Ounces.

Functional Components:

When it comes to using the power bank, there are a few things to know.

It does have a retractable AC adapter that comes out and goes back.

There’s a power button above the two charging ports, and you do have to press it to start charging. Also around the power button, there’s a LED light that has three colors.

Green  = 66% – 100% of Power Capacity Left [Refer to the first image that we used in this article]

Blue  = 34% – 66% of Power Capacity Left

Red  = 1% – 33% of Power Capacity Left

Build

Structure and Material:

The build quality of this power bank is pretty good, the AC adapter feels solid to use and doesn’t feel like it’s about to wobble and break out of its spot. It snaps out and right back into place.

The LED light around the power button looks pretty good, and it’s quite different than what most other power banks use.

The charging ports hold strong to the cables that you place into them. However, the power bank is made of plastic, so if you drop it from a high enough height it and onto hard flooring, it could break.

Tech:

On the tech side, the power bank does get warm if you’re recharging it and charging from it at the same time. This is known as Pass-through charging and has been known for heating up a power bank, actually decreasing its overall capacity a lot faster because of the heat generation.

Reliability

This power bank is going to be most reliable for those that own a USB-C smartphone, as the USB-C port is the port that holds the most value, of the two ports on this power bank.

The ability to recharge the power bank from an AC outlet is useful and using it as a wall charger at the same time.

Summary:

Power:

There’s enough power capacity to charge most smartphones to full power about one time and still have some power left over.

The USB-A port and USB-C port are standard ports, but of the both, the USB-C port can be more useful if you have a USB-C smartphone.

Design:

The use of a LED light with different colors is new and pretty cool to see. The use of its retractable AC adapter makes the power bank a lot more portable.

Build:

The Jackery power bank does tend to get warm if you’re recharging it and charging your devices at the same time. As pass-through charging is taking place which can generate heat.

Reliability:

This Jackery 2-in-1 wall charger power bank is going to be most useful for those that own a USB-C Android smartphone, as the USB-C port offers the faster charging speed.
