myCharge RazorMax 6000mAh Battery Review
      #48078 - 05/26/15 08:27 PM

A couple of years ago we looked at the myCharge Hub 6000 portable battery with 6000mAh power and two built-in charging cables. The myCharge RazorMax 6000mAh Battery offers the same capacity battery, though with a better conversion rate, but slims down to half of the Hub 6000's thickness. It's a great battery for a short trip or daily use. The myCharge RazorMax 6000mAh Battery offers two charging ports and can charge smartphones, tablets and other smaller electronic gadgets.


The myCharge RazorMax 6000mAh Battery comes in a gunmetal gray curved block and it's a lot slimmer than the Hub 6000. The Anodized Aluminum housing provides strong protection for the battery cells inside. The RazorMax 6000mAh measures 4.4 x 2.6 x 0.5 inches and weighs 6.2 ounces. The battery has two full size USB power output ports and can charge two devices simultaneously. Both the power output ports and the micro USB recharging port live on one side of the battery and there's no control button to operate the battery. To check the four small white LED lights for battery power level, simple shake the battery to turn them on. When you connect the battery with yoru smartphone or tablet, it'll start charging automatically. And if it doesn't, again shake the battery to turn charging on.


The RazorMax is a lithium polymer battery and it features smart-sense technology. It ensures correct identification of devices it's charging and safe charging. The high density battery has good standby time and its power transfer rate seems to have improved a lot since the Hub 6000. The battery also supports power pass through, which means it charges connected device and the battery itself simultaneously. It takes overnight recharging for the battery to fill up from empty.

Unlike other batteries with USB ports, the myCharge RazorMax 6000mAh Battery doesn't mark the output power amperage on the ports, but their combined output is 2.4A. We tested both ports and either one could charge either a smartphone or a tablet like the iPad Air 2, and it charged both an iPhond 6 and an iPad Air 2 simultaneously. The RazorMax has a better conversion rate than the Hub 6000. In our tests, it could charge the iPhone 6's large battery at least twice from nearly empty to full and it could charge the Samsung Galaxy S6's large battery at least 1.45 times. Charging speed was faster with the iPhone 6, taking about 2 hours to fill a full charge; while take about 4 hours to charge the Samsung Galaxy S6.


If you don't need the built-in Lightning and micro USB charging cables on the Hub 6000, you gain a much thinner battery for more power with the RazorMax 6000mAh battery. The smart battery can charge two devices at the same time, and it's great for any traveler or commuter to fill up their phone's battery on the go or top up their devices to make it through the day. We like the slim-down form and the plug-and-charge design.
