    this is the second 20K MAH portable battery I own from anker, and this new one is just as good, if not a little better. It has two full size USB ports and a usb c with PD ( Power Delivery) capability. I mainly use it to charge my iPhone and Mirrorless cameras while I'm at work or on the road, but it puts out enough power to charge my iPad Pro, Nintendo Switch also. It would have been really cool if it could juice my MacBook Pro also, but it can't. My MacBook recognizes that it is plugged into a power source, but it says not charging. Anywho! This power bank is nice and slim, Its a little longer than my iPhone 13 Pro, and I would say about 2x as thick as my phone. it doesn't weigh a whole lot, so it is quite portable. I throw it in my book bag and go. I can usually charge my phone fully about 4 times before I need to plug the battery back in to recharge. Even then, it isn't fully depleted but I don't let it drain completely dry. I like to charge it up, just in case I need to charge something else or lend it to a friend or family so they can charge their phone. It comes with a small carry bag and USB C cable, which you can use to charge your devices and charge the battery. One thing to note is that it does not have a magnet like the page claims, don't know if it is a listing error or my unit just doesn't have it. Either way, I don't think its a deal breaker, since I prefer to charge my devices with a wire. It's still the best way to charge a device. The battery does have a "trickle charging" feature, for low power consumption devices. I honestly haven't used the feature much, since I would like to charge my devices up as quick as possible so that I can go back to using it. Would I recommend it to a friend? Yes. Especially if you are like me and own many rechargeable devices and take them with you. It is a great back up charge for just about anything, and it packs a lot of power. Even if you don't use it often to charge your phone, It will hold its charge for weeks or even months at a time for you. Last winter , as you all may know... we had a big power outage here in Texas and this type of Anker battery pack saved the day for me. I was able to charge my phone everyday for 4 days while the power was out with it. I definitely think every home should have at least 2 of these charged and ready.

    Good sized battery brick. Charged up in reasonable amount of time and quickly charged my iPhone and iPad. I like that it has both USB-A and USB-C. Came with little pouch too. Good item!

    PowerCore III Sense 20K mAh Charger

    The Anker PowerCore III Sense 20K mAh portable battery charger has enough power to keep my iPhone 7 charged and recharged 5 times before needing a recharge itself. There are 2 USB A and 1 USB C ports. It took over an hour to charge the unit from 1 light to full power. In the box was the Charger and 1 USB-C to USB-C cable, along with a mesh carrying bag. For the size and power rating this unit surprisingly light. The only thing I had a problem with was the battery life notification lights. I found them hard to see in the daylight. I would recommend this product to family and friends.

    Anker - PowerCore III - Excellent Battery Pack

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Love this Anker PowerCore III Sense 20K mAH 20W Battery Pack. I can get at between 2-3 charges of my mobile phone, possibly more, from only one power-fill to full. I have two others that I only get 1.5 charges out of. This 20K charge lasts so much longer. A little more money, but well worth the cost.

    We had several phones that we were able to charge during our international trips. My kids would have been miserable if they can’t use their cellphones. It charges the phone fast. Would be nice if it came along with most common charging cables.

    I recently bought this in case of a power outage in my area, but I’ve been taking it with me wherever I go because it’s nice not have to worry if my phone was fully charged before I left the house.

    Nearly ideal.

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Does the job, does it well. Capacity is more than enough for most needs, offering 2.5 charges on my Note 20 Ultra. However, some form of built in tuckable USB-C output would make this the ideal portable power bank.

    Not enough information before buying

    It is heavy. You have to buy a separate charger unit in order to charge this for an additional $40. When it is fully charged, it will quickly charge two devices.
