Massive battery 15,000 mah and even an LCD flashlight for a nice price

The Intocircuit charger has an impressive build and feels very sturdy with aluminum exterior.

Another nice feature is the LCD screen. Unlike some other chargers, which use a series of LED lights to give you a rough estimate of how much juice is left, this display is much more precise.

Another great thing about the Power Castle's dual USB ports is that it charges two devices at once just as fast as it charges a single device at any given time. This means that these two USB charging ports are indeed rated to provide an equal output of 2.4A of current for super quick charging.
- Gadget Mac
This battery pack provides two USB ports, both of which are capable of charging any modern device at a decent clip with up to 2.4A of power draw per port.

The Intocircuit also has a nice blue LCD screen that shows power level, charging and discharging status.

What I discovered after having done this, is that it's best to know how to most effectively use this product. For example, there are two USB ports, one of which is better for Android charging (the 1.0A is dedicated).

I found the LED indicating the amount of energy remaining to be very useful in helping me decide when to recharge the power bank since high power drawing devices such as tablets that require more juice for a full charge.

Another major differentiator from other power banks is that on top is a small backlit LCD screen that reports remaining battery percentage and output status.

What experts didn't like
Only 2 USB ports, and the unit does not take quite some time to charge the internal battery.
- BestReviews
Unfortunately, when I tested the charger again last week. The battery level dropped to 0% and all my efforts to charge the power bank failed. I tried to charge it again with different cables and wall chargers but it couldn’t hold the charge at all.

Limited to 500 or so recharge cycles over a lifetime.
- Heavy
But that's not to say that this battery is poorly built and made. Because it really isn't. Now it's not impressively put together, nor does it feel premium by any means.
- Gadget Mac
It takes a very long time to charge the unit itself; even if you have a 2A+ wall wart to charge the unit, it will take many, many hours to go from 0% to 100%. Typically not a huge deal, but when I'm on longer trips, I don't always have a full day I can let the unit sit and charge somewhere.

The Intocircuit is heavy and dense. If you're like me, and love to travel light, this might be too heavy for you. 14.08 ounces isn't exactly dumbbell heavy, but it is heftier than most like it.

This unit is also slightly heavier than its competition.

The only small issue is that this device is not provided with an AC adapter to recharge the power bank.

The Power Castle is currently priced isn’t cheap in the world of power banks.

An Overview On Portable Chargers

There’s no shortage of portable chargers available. In fact, once you start shopping, you’ll likely immediately be aware of the vast array of products out there. But although portable chargers may look alike, some even promising very similar specifications, there are notable differences from one product to the next.

Simplemost Media

One of the biggest features to look at when shopping for a portable charger is how long it will take to charge your devices. This is especially important if you have a device with fast-charging capabilities since not all portable chargers support that. A device that can fully charge multiple items at once in a limited amount of time may be well worth paying extra or sacrificing other features, such as portability.

Simplemost Media

Another feature that sets some newer chargers apart from others is the ability to charge more than just a smartphone or tablet. Some of these devices can charge a laptop or gaming console, making them useful if you’re regularly out and about with these items. You’ll also find some chargers can plug into your computer and act as a hub, charging multiple devices at once while you’re working.

Simplemost Media

While all portable chargers are designed to tuck into backpacks and laptop bags, some are even more powerful. If it’s important to be able to slip your charger into a pocket or handbag, look for much smaller devices. Some are only slightly larger than a tube of lipstick, making them especially portable, but you may sacrifice power and charging capabilities for that convenience.

Simplemost Media

While you’re waiting for your devices to charge, you may occasionally want to check in on status. Some chargers have indicator lights that show you exactly where you are in the process, giving you a general idea of the time you have left. However, if you’re only charging smartphones and laptops, you’ll likely be able to get this same information by looking at the device itself.

DWYM Fun Fact

USB-C is poised to revolutionize the way devices are charged. Instead of having multiple ports on a device for all the different cables you need, with a USB-C, you can use the same port as both an input and an output. This can be seen on newer equipment like MacBooks. You can either plug your power cord or your USB charging cord into any of the ports provided, aside from the headphone jack, but even that is changing. Some phones replace the headphone jack with a USB-C port, although you’ll still find the traditional 3.5mm headphone jack on laptops. The goal with USB-C is not only to streamline the ports that devices need to have but also to provide a single standard that will make life easier for everyone.

The Portable Charger Buying Guide

  • A good portable charger starts with its power. Portable chargers can range from 10,000 to 26,800 mAh.
  • The time it takes to charge is also a top consideration. Although this can vary depending on the capacity of each device you’re charging, some portable chargers have the ability to charge two or three devices at once at a lightning-fast speed.
  • Before you can charge other items, you’ll need to charge the portable charging device. You’ll want to evaluate your new portable charger on how quickly it charges up, depending on your needs.
  • One factor determining how quickly your portable charger can get results is whether or not it supports the new fast-charging capabilities built into many modern devices.
  • New charging technologies built into devices like laptops and gaming consoles make it easier to build portable chargers for them. Some portable chargers can not only charge your smartphone but can also capably charge the newer MacBooks that have Thunderbolt ports, as well as the Nintendo Switch.
  • If you’re concerned about portability, look closely at the weight and size of the devices you’re considering. Do you need a device that you can carry in your pocket, or is a slightly larger charge OK for your needs?
  • Some portable chargers have longer, slimmer profiles, similar in shape to a smartphone. The measure around 6 inches by 3 inches, meaning they’ll still easily slip into a laptop bag or purse, but they may not be quite as easy to carry around all day with you.
  • Portability comes at a cost, however.  Smaller chargers can typically only charge one device at a time. Larger chargers can charge up to three devices at once.
