Disclosure: I was able to keep the review unit mentioned in this post.
TL;DR – There are higher capacity chargers out there for a better price.
The Magicstick itself is a small rechargeable 2800 mAh lithium ion battery (Input: DC5v / 0.55A, Output: DC5v /1.0A), with 2 USB ports (one micro, one full), comes in 8 colors, costs $49.99 and that looks so much like a flashlight that it could be mistaken for maglite. It comes complete with all the cables you need for charging USB (micro USB) devices, although you’ll need to use your own cables if you’re charging an iPhone.
It takes between 5 and 6 hours to charge the Magicstick which can be accomplished via a USB charger or AC wall outlet charger (not supplied) or any compatible high current USB port (using the supplied cable). The amount of charge remaining in the Magicstick is indicated by an LED light that activates when you depress a button on the top of the device – Blue light = 70% – 100% full, Green light = 30% – 70% full, Red light = 1% – 30% full.
As you can see from the picture of the box (and the their website), the Magicstick promises up to 2 full charges for smartphones (including iPhones and Android phones), cameras, portable gaming devices, Mp3 players and more. This extended battery is not for charging tablets. While it technically can provide a charge to an iPad at best you’d only get about 10% charge on an iPad Air.
I tested the Magicstick with my Nexus 4 and was unable to get the the phone to ever charge above 85 – 87%. The Nexus 4 has a 2100 mAh capacity battery so it should have been able to receive at least 1 full charge but after testing in various scenarios I was unable to achieve this.
I tried various scenarios, always starting with a 100% charged Magicstick which had been left to charge overnight for 12+ hours) such as charging the Nexus 4 while it was powered on (but not in use), with starting battery level at 7%. I would assume that charging “powered on” is the most common scenario for most users who require an extended battery.
I also tried charging with the Nexus 4 while the device was powered off and fully depleted (the phone had shut itself down from lack of power). In either case I couldn’t get the phone to charge above 85 – 87%.
The iPhone 4S and 5S have 1432 mAh and 1440 mAh batteries respectively, so should achieve a full charge without problem, however there is no way, even on paper that they could achieve two full charges.
I don’t have a feature phone to test the Magicstick on, but I could see it (on paper) living up to its promise of “up to 2 full charges” on such a device. But for modern smartphones the Magicstick simply won’t cut it as a decent extended battery.
Powerocks do make extended batteries with larger capacities, such as the Magic Cube 9000 and 12000 but these are quite expensive at $89.99 (9000 mAh) and $109.99 (12000 mAh). A quick search of Amazon has extended batteries such as the Anker Astro E4 13000mA and the New Trent iCarrier 12000mAh getting great user reviews with higher capacities and lower costs than the Magic Cube.
At the end of the day I simply can’t recommend the Magicstick, even at the $40 – $50 price range. I wanted to like it, I really did, but other manufactures make higher capacity, visually and technically similar devices such as the Anker Astro Mini 3000mAh Ultra-Compact Portable Charger which comes in at a full $10 cheaper.
