Lumsing Grand A1 Plus 13400mAh Portable Charger Review
      #48680 - 10/09/15 07:20 PM

When we think of portable batteries that have over 10,000mAh capacity, we picture large and heavy blocks. Lumsing's Grand A1 Plus 13400mAh changes that perception by offering 13,400mAh power in a small and relative light package. The Grand A1 Plus measures 3.85 x 3.11 x 0.83 inches and weighs 9.2 ounces. It offers 2 USB charging port with max power output of 3.0A and can charge two devices at the same time. The Grand A1 Plus comes with a USB charging cable.


Lumsing Grand A1 Plus 13400mAh Portable Charger is the largest power bank in the Grand A1 series of power banks, which includes the Grand A1 Mini 6700 and the Grand A1 Fit 10050 in addition to the Grand A1 Plus. All the Grand A1 batteries have a similar design: black aluminum alloy casing with orange accents and shiny black plastic ends. The metal body protects the battery cells from bumps and drops, and the battery looks to be well made. The metal surface is matted so it isn't slippery. All the ports including the 2 USB charging ports and the micro USB recharging port live on one end of the battery along with a modestly strong flashlight. The battery has a push power button that you can use to turn on charging and the LED lights. The four tiny LED lights live on the top of the battery and they indicate power levels and recharging status.


The Lumsing Grand A1 Plus 13400mAh Portable Charger has LG battery cells with build-in protection against overcharging, over discharging, over voltage, short circuit and more. The battery has intelligent circuit that detects the devices you're charging and use fast charging where it can and when it's safe. The two USB charging port outputs 2.4A when one is in use and 3.0A when both are in use combined. You can charge a tablet and a smartphone at the same time. The battery can be recharged using the included USB charging cable and it takes overnight to fully recharge it. The Lumsing offers over 500 full recharges.

The Lumsing Grand A1 Plus 13400mAh Portable Charger is powerful enough to charge both tablets and smartphones. In our tests, the battery filled an iPad Air 2's battery from 15% to 100% with more power to spare. It filled the iPhone 6s' battery at least 4.5 times, and the Samsung Galaxy S6's battery more than 3 times. Even though the output max power is 3.0A, our tests showed that battery didn't charge devices very fast. It took 5 hours for the Grand A1 Plus to charge the iPad Air 2, 3 hours to charge the iPhone 6s and 4.5 hours to charge the Galaxy S6.


If you're on the road a lot or take long overseas flights, the Lumsing Grand A1 Plus 13400mAh Portable Charger is a great choice. It offers not only a lot of power but it's also exceptional small and reasonably light. The battery can charge both smartphones and tablets and it can charge two devices simultaneously. The Grand A1 Plus has sturdy build with metal casing and comes with good safety measures to ensure safe charging of your electronic devices. Perhaps the most attractive feature is its low price. The only thing to be aware of is it doesn't charge or recharge very fast.
