Emie Power Blade 8000mAh External Battery Charger - Dual 2.1A output ports - Unique design - Recommended

The Emie Power Blade 8000mAh External Battery Charger is one of the most unique power blades we have tested; we received the blue one, but the only difference is the exterior color.

This power bank is designed for a specific mission; to live inside your planner or small 3-ring binder, waiting for the opportunity to charge your devices while on the go. However, this thing is so thin that I carry it in the pocket of my laptop bag (tried it in the outside front, inside center, and outside back pockets...) and, because it is so thin, you can not even tell it is there. That's kinda cool, and power 'blade" is quite a fitting name for it. I would recommend this power bank to others for similar use.

Packaging was sleek - it comes with a hardcover planner-style "book" that you could store it in for ultra safe keeping, and it has a felt pocket carry case that is much more portable than the hard case. The micro-USB cable and user guide are also included inside the box. This battery pack has great capacity - 8,000 mAh - but it is its unique size that really catches attention: Approximately 8 3/8 inches long, 5 1/2 inches from left to right, but just 1/4 of an inch thick... "blade" thin, if you would. Its weight is comparable to other units of this capacity, coming in at about 10.3 ounces.

Upon receiving the battery, we plugged the unit into our wall adapter (used my Samsung S3's wall adapter) and found that it arrived with no charge from the factory, signified by one of its four green LED lights blinking and the other three being dark. Though the stated input is 2.0A and we were using a 2.1A wall charger, charging took 14 hours to complete. As the 14 hours passed, lights took turns changing from blinking to being constantly on, until all four lights were fully lit up -- signifying a full charge.

Operating this unit is a breeze -- its two ports are said to produce 2.1A output each though one is optimized for IOS, and the other for general use. All you need to do is press down on the built-in USB port to fully expand its opening, slide your charging cable's end into that port, connect the cable to your device, and remember to hit the power bank's on button to get the juice flowing. The Manual that comes with it is basic but informative, though written in very small type.

The storage capacity of this battery is very good and the charging times we experienced from either 2.1A port were actually quite good. We tested it with a Samsung S3 and and HTC Droid DNA and the rate was about 45% charge per hour for the batteries in those phones which average about 2200mAh in capacity (about 3/4 of a percent per minute). That's about twice as fast as we get from our wall chargers, so it seemed to perform very well.

We did not notice any heat build-up from the phones or the battery during the charging process.

The retail material notes that this power bank is covered by a six month's limited warranty, so if an issue arises within that period I will return here to update the review and let you know what the issue was and how resolution was handled. We did receive this unit gratis from the seller and have put it to use to objectively find out how well it performed. My statements here reflect that testing.

We found this power bank to be of a uniquely super thin design that would serve multiple purposes, like carrying in a small binder, travel bag, tablet pouch or laptop bag without even noticing it, and it did the job as described by the manufacturer though it did take a little bit of time to charge the power bank itself. If you are looking for a battery pack of this color, capacity, size, interesting style and charge rate, for use as I have described above, then we would recommend trying this unit from Emie based on our experience with it.


Go for it.
