Quick Charge Power Bank, BlitzWolf QC3.0 Portable Charger 10000mAh Dual USB Compact Qualcomm Quick Charge External Battery Pack Support QC2.0
Solid and compact charger with a lot of capacity
This is one solid little power bank. It’s like a small brick. The way it’s built and it’s heft very much gives the impression that it’s not a cheap item.
First off it’s a Qualcomm 3.0 rated charger which means that devices which charge at different voltages to achieve full capacity faster than the average USB device can be connected and charged from this little guy. It’s still very much backwards compatible with older USB powered devices. I’ve tested it on these devices:
► BlackBerry PRIV
► BlackBerry DTEK60 and 50
► Lumia 650
► Samsung Galaxy Tab
► iPhone 4S
► Several different Bluetooth speakers
► Various headsets and other devices
The power bank had no problem charging two power hungry devices at the same time. There was some voltage drop when higher current was being drawn but for most phones the bank can supply enough current to keep the charge rate up. Being able to maintain the 5volts is important. Many cheaper power banks and chargers let the voltage drop when more than half an amp is being drawn. This causes problems such as heating in the phones charging circuits and makes the whole charge cycle take longer. Here the voltage stays at just over 5v where it belongs and this is while current is being drawn on both ports.
You can see in the one image that the IQ port is capable of delivering higher voltage to any device that can use it.
Like most other power banks there are 4 LED’s that indicate the batteries charge state – 25, 50, 75, and 100%. Also, while charging the bank one of the LED’s will blink letting you know that its connected and charging. To check the battery status a quick press on the power button lights the LED’s up for me. I can charge the bank with either the included USB to USB micro cable or one that I already have. Since it does have 10,000 Mah capacity it takes a while to charge the power bank and charge rate will depend on how much current the charger is available. With a Qualcomm charger, it took me 4 hours to get from about 50% to full capacity. Like other power banks I’ll be letting this charge overnight.
The power bank never heated while being charged or while charging, even when two phones we connected.
The 18-month warranty is a bonus.
