What experts liked
Massive battery 15,000 mah and even an LCD flashlight for a nice price
- BestReviews
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.
- Heavy
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.
