Capacity & Charging speed

The EC Technology 22400mAh Power Bank is the first piece of kit we’ve had the chance to review from this manufacturer – and it doesn’t disappoint! Hailing from Texas USA, EC Technology have certainly managed to cram a whole lot of power into this portable charger. To give you an idea of what we’re talking about, 22400mAh is good enough to recharge an iPhone 6s eight times!

One of our favourite features of the EC Technology 22400mAh Power Bank is it comes with three separate USB output ports. For heavy users with multiple devices, this means you can simultaneously charge your electronics when you can’t get to a wall socket. This would be the perfect device for a long haul flight or a road trip.

The three output ports are rated at 1A for iPhone, 2A for Samsung Tab and 2.4A for iPad. (Each port is labelled.) It comes with AUTO-IC technology, which will automatically recognize what type of device you have plugged in to charge, and deliver the fastest, safest, most efficient current. And with over-charge, over-voltage, over-current and short-circuit protection you can be sure your expensive electronics are in safe hands.

The EC Technology 22400mAh Power Bank has a single DC 5V 2A input port for recharging the device. Charge times are pleasingly quick, although keep in mind the battery is huge – so don’t expect miracles! We’d certainly recommend purchasing a quick charge wall charger such as the Aukey Quick Charge 2.0 Wall Charger (if you don’t already own one). This will see your recharge times quicken considerably.

Look and feel

The EC Technology 22400mAh Power Bank has a no-nonsense rugged look to it, that’s backed up by its high power output. Easy to hold due to its rounded edges, the plastic body feels solid and well constructed. The textured plastic reflects light subtly due to its dull sheen. The device comes in three colour ways – we tested the black and red model. The main part of the body is in black plastic, and is offset by a red strip that runs around the narrow edges of the power bank.

On the top side of the device you will find the EC Technology logo as well as four LED power lights to indicate charge level. At the business end there are the three USB output ports – each is labelled for its intended device (iPhone, Samsung tab and iPad). Above the output ports is a small flashlight which is reasonably bright and could be a welcome feature for some users. Flip the power bank over and you’ll find the power button on the leading edge, with the micro-USB input port and on the other side.

Durability & Construction

The EC Technology 22400mAh Power Bank feels extremely well constructed and rugged. The plastic body feels thick and solid, with excellent fit and finish. The ports all seem well made, as plugging and unplugging cables was smooth and easy every time. On some cheaper power banks you can feel some flex, particularly when unplugging cables – it can sometimes feel as if you are going to rip the port out of the body.

The power button also feels springy and well made, although we’re not set on its location on the leading edge of the power bank. This is becasue we did accidentally switch the device off when carrying it in our bags (something in the bag must have bumped against the switch.) We’re also unsure of the warranty conditions for the EC Technology 22400mAh Power Bank which is not great. We’d like to see at least a year warranty provided as standard.


We won’t sugar coat this for you – the EC Technology 22400mAh Power Bank is not a featherweight. Weighing in at 1 pound, it is certainly towards the heftier weight scale of the ~20000mAh power bank market. We’d certainly rate this as a heavyweight, but then that’s to be expected at this power level.

Whilst its not the lightest power bank in this power category we feel that’s offset by its solid build and construction. Its also not nearly as big as some of its competitors. At 0.9 inches high it has a very flat profile, with a length of 6.3 inches and width of 3.1 inches. The slim profile makes it easy to slip the EC Technology 22400mAh Power Bank into a laptop bag. Whilst the rounded and bevelled edges make it easy to hold.

The EC Technology 22400mAh Power Bank is an ideal purchase for power users with multiple devices to charge. Its rugged, no-nonsense aesthetics will appeal to some, but not to all. For the money you'll get solid construction, three USB output ports and charge times which are quite good for a power bank of this capacity. Keep in mind, buying a quick charge wall charger will speed those charge times up considerably. All in all this a really well built, good value power bank from EC Technology.
