Product Information

We want you to live without the inconvenience and uncertainty of where your next charge is coming from. The thing for me though is I’m pretty much always near an outlet of some sort… I don’t really know what you would need a portable charger of this size for.

If you plan on storing the battery for a month or longer, try to leave the battery at about a 50-75% charge to prolong battery life in storage. That probably means you won't get seven charges for your phone, but it'll still be quite a lot depending on how big the battery inside your device is. The PowerCore comes equipped with two USB ports that can quickly charge devices thanks to each port supplying 2. There is no blue lights on whilst my device is plugged in either, which on all my other power banks has the blue lights on whilst charging.Also important to understand than USB-C bidirectional so when you charge it you just plug in the USB-C USB-C cable to a USB-C charger, and when you want to recharge it press the power button and then plug in to a device otherwise it will take power rather than give power. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. But is it the right size for you and will it suit you to recharge your phone, tablet and other accessories on a daily basis? These include power lost from circuit heat and voltage conversions from the battery, the charging cable and your device. Pressing the wheel activates the LEDs to show how much battery you have left, and holding it down longer activates USB-C output.

Every time I charge the Power Bank at night and when I woke up the next day, I see the last LED light blinking, I thought its full charged and ready for use. The Griffin Reserve lasted a little longer when powering the iPad (30 hours, 4 minutes), but with its two relatively low-power USB-A ports, it's unable to power USB-C devices like the MacBook. Also note that there are three different iPad wall chargers (going solely by memory here): one is 5 watts/1A (iPad mini 1st gen and included with most, if not all iPhones as well) one is 10 watts/2. The 20,100mAh Anker PowerCore+ has enough juice to charge a tablet several times, or keep a MacBook running for hours.I know it’s like 10 months later but I figured I’d throw my 2 cents in since it’s a direct reflection of my life. Actually, after 12 hours of charging still the Power bank is not fully charged, the last LED keeps blinking. Therefore, if you can only charge the battery for a few hours at a time, that is OK as it keeps the electrons moving in the battery.
