The perfect portable charger for anyone looking to charge multiple devices.
Even though I’ve been reviewing portable batteries for several years now, I still find options out there with unique charging abilities that make it better than some other portable chargers on the market. Sometimes, the charger is ultra slim and other times it’s got an incredibly high battery capacity. The case with the RazorMega is that it combines both high-capacity with an ability to simultaneously charge multiple devices at one time. That’s what makes this battery worth having.
The RazorMega has an extra large battery capacity of 20,000 mAh and it recharges via Micro USB. It has 2 USB-A charging output ports that deliver a maximum of 5V/2.4A of power. The power bank weighs approximately 1 pound and measures 2.6″ x 0.9″ x 6.8″ in size. The battery has smart-sense technology built-in to ensure device compatibility with all smartphones, tablets, and other portable devices. It incorporates hyper-charge which is meant to charge devices up to 65% faster than other portable chargers. The RazorMega also has a rapid rechargeability and will regain its charge up to 50% faster than competitors. This power bank also has a passthrough charging ability so that you can charge your devices and the battery together.
I recently took an extended road trip with family and found myself without access to a power outlet several times while I was out of town. I grabbed up the RazorMega, a Lightning cable, and my phone. I was able to let my phone charge while we were still sightseeing and not have to worry about whether or not the battery had enough power to handle charging my phone up. As I mentioned, I do have several different batteries and the smaller capacity ones will sometimes give up before my phone is charged up completely. One of the nice things about the RazorMega is that I could charge my phone completely and still have a charge left on the battery to use it again. This was a HUGE convenience for me while on the road because I didn’t always have a chance to stop and recharge the battery.
Another really great example of how well the RazorMega works leads me to the Fourth of July. My family and I ventured out to a local riverfront to stake out good seats for the show at nightfall. This time of year, it’s extremely hot in our area and we were actually under a heat advisory. That said, we did take precautions to keep ourselves cool and well-hydrated throughout the afternoon. One of the things we did to keep ourselves cool was to utilize small rechargeable, hand-held fans. Both fans had input voltage/current of 5V/1A and the battery was 3.7V. While the internal battery on the fans held up for a while, we were using these fans constantly and as a result, they lost power. To keep them going and keep us from melting, I plugged them into the RazorMega. Even in the 95º degree heat, the power bank performed admirably. The fans kept going and the RazorMega is still showing a full charge — even after charging my iPhone 7 up to 40%.
In addition to those two fields tests, I did actually just have some statistics from an iPhone charging session I completed at my desk. After 32 minutes, my phone had gained 30% battery life. That’s approximately 0.94 percent per minute. In my experience, that’s a pretty quick charge for these portable batteries. I also tested the power delivery voltage using a USB Digital Tester and found that the iPhone 7 tested with 4.95V/1.15A and my 12-inch iPad Pro tested with a reading of 4.95V/1.38A. I never once found that the battery overheated.
Even though the RazorMega is a little cumbersome to carry around in a pocket, it’s definitely a superior power bank in my opinion. The only issue I had with it during testing was when it came to recharging it. It recharges using a Micro USB connection. I plugged in into another portable charger, which has the ability to power most devices. For some reason, the pass-through power delivery of that charger was not the right type of current to charge the RazorMega. When I discovered that issue, I plugged the power bank into the wall using a power adapter and it worked fine.
The RazorMega does retail for around $70 (at the time of this article) so it’s priced a little higher than some power banks, but given the longevity of the battery life and the efficiency at which it charges, I would recommend the RazorMega for any user.
