Review: Jackery Jewel Lightning Power Cable

Jackery Jewel Lightning Power Cable











  • Uses a Mini power bank that can charge about 15%
  • Very portable as any other charging cable
  • Great for emergencies


  • Slow Charging and it doesn't charge too much

Power banks are a versatile type of charging technology because they can be mended into many different technologies. Sometimes they double as wall chargers and some are even car chargers.

Some power banks can be really big because they have a high power capacity and some are really small because they have a small power capacity. If one thing is certain about portable chargers is that they’re, well, portable.

That is the main thing within their nature that will always be prevalent because it’s power without the setbacks.

In this case, though, the power bank takes a whole new form that is quite uncommon but highly sophisticated to use which is being implemented into a charging cable. This is the Jackery Jewel.


Power Capacity:

So the power capacity of the Jackery Jewel charging cable power bank is very low because the power bank part of the charging is very small since it uses a very tiny Lithium Ion battery.

The power capacity it provides is 450mAh and even though that’s not a lot of power, that’s not really the point of the Jackery Jewel. What is the point is that the charging cable even has a power capacity to use.

With that said, the charging cable is the only usable for Apple devices like iPhones and iPads that are able to use a Lightning charging cable. For most iPhones, you’re going to at least get about 15% of battery capacity and that can increase your standby time to about 3 hours.

We realize that Jackery claims that the Jewel is able to restore about 20% more battery life left, but at Charger Harbor, we also account for energy lost during charging.

Also, even though you can use the Jackery Jewel on iPads, it won’t be very useful because the power that it restores is going to be very minuscule.

Output Charging:

Output charging speeds are expected to be slow for a power bank that is so tiny. The Jackery Jewel has an Output charging speed of 5V/1.0A.

So it won’t charge your iPhone 6/7 or iPad at their max charging speeds, but at least it’ll charge them. There’s no need to connect the charging cable to a USB wall charger until the power capacity the Jewel has is fully depleted, so that means you can just connect the charging cable to your phone and it’ll begin charging.

Input Charging:

The recharging speed is the same as the Output with it being able to recharge at 5V/1.0A.

Recharging of the Jackery Jewel Lightning Cable power bank is done by connecting it to a USB wall charger and that will result in the power bank being recharged, and if you’ve got your phone connected while it’s being recharged then the Jackery Jewel will also begin charging your phone.


Size and Weight:

The charging cable is 3.3 Feet long and weighs 1.2 ounces. Even with the addition of a power bank section on the charging cable, it’s just as portable as any charging cable.

Functional Components:


Well, the Jackery Jewel is basically like any other charging cable, but this one has a power bank in the center of it. The power bank portion of the charger is about 3 inches long.

When you’re using the Jackery Jewel just by itself, then the button must be pressed to begin charging. If charging is happening through a USB wall charger then you don’t need to press the button because charging automatically starts.


Structure and Material:

The charging cable has a very usual build because it’s just wrapped in rubber and so is the power bank portion of the charger. However, the power bank piece of the Jackery Jewel has been drop tested and that can be thanked to the wrapping that’s around it.


Even with its small size, the charger is still able to hold lots of certifications because it has about 9 layers of safety features. The certifications that it has to include are RoHS, FCC, and CE.


We think that the Jackery Jewel is a beautifully executed concept, but it’s important to remember what it offers.

It’s only limited to devices that can take the Lightning charging cable to charge, and the power capacity of the built-in power bank is only 450mAh that can only add 15% of the power capacity. It’s the fact that you can have portable power and a charging cable that makes the Jackery Jewel so useful to use.



The power capacity is just enough to give you about 15% of power capacity and just has a charging speed of 5V/1.0A.


Very well designed. You can charge through the power bank by just connecting the charging cable into a device, and press the power button to begin charging. All without needing to connect the charging cable to a wall charger.


It’s quite sturdy with the Jackery Jewel actually being drop tested.


It’s not capable of providing near a full charge at all, and neither can it provide the fastest charging speeds. However, what the Jackery Jewel can provide is power and charging when you need it most and it can provide just enough of it.

Specs of the Jackery Jewel Lightning Power Cable:

  • Capacity:            450mAh
  • Output:   5V/1.0A
  • Input:      5V/1.0A
  • LED Power Indicators: Just uses a small Green Light
  • Size: Charging Cable is 3.3 Feet long and the Power Bank portion is 3 inches long
  • Weight: 1.2 Ounces


There’s not many like it, and we actually think that the Jackery Jewel is basically the first of its kind so it’s hard to give it some standards.

However, for what it can do, the Jackery Jewel is an amazing portable charger and even with its heavy limits, it’s still able to provide just enough power and a beautiful design that is fantastic to use.
