Anker PowerCore Slim Power Bank (Open Box)

Was unsure about whether this would meet my needs but this exceeds expectations. Charges my iphone almost 4x without needing a recharge for the brick. Charging is fast for USB-C to lightening cable (which is what I need for my iphone) and probably would be even faster if you are charging USBC-C to a newer iphone(11 or later). The USB-C is PD--please not this and make sure you cables you have allow for this quicker charge feature. The brick has both the lightening USB-C PD charging port output and the USB-A charging port output. This comes with the Anker Nano III wall plug (USB-C Only connection) and the USB-C to USB-C cable so you don't need to buy anything extra to charge up this product (unlike other listings for similar Anker bricks). The only thing you will need to purchase if you don't already have one is a USB-C to lightening cable to attach to your phone (if you need a lightening cable to charge your phone----but make sure that you have a USB-C to 'whatever size you need to attach to your phone"-----on hand or a USB-A to "whatever size you need to attach to your phone" so that you can use this product to charge your phone as the brick requires a USB-C to 'whaterver attachment your device requires" or a USB-A attachment to "whatever attachment your device requires" to attach to the brick itself. You CANNOT attach a lightening cable to lightening cable to this brick itself---you must have a USB-C or USB-A on one end at least. If the product you wish to charge requires a USB-A cable, you can use the cable you already have as this brick has a USB-A output BUT make sure that you cable is equipped for fast charging and if not, you may want to purchase a new USB-A cable that will allow you to take advantage of a bit of a faster charge from this brick. Review all the specs for this product in the main description to exceptions to this and other info(not gonna get it all down in this comment). Please note that this model ONLY allows you to charge it (i.e. the brick itself) by using a USB-C to USB-C cable (the USB-C cable slot on this model brick is the ONLY slot that allows input from a charger---the USB-A slot is OUTPUT only!!). Again, the USB-A slot on this brick is OUTPUT ONLY; the USB-C slot on this charger allows for INPUT and OUTPUT but the USB-C slot is the ONLY SLOT THAT WILL ALLOW YOU TO CHARGE THIS BRICK! If you require a lower power charge for your bluetooth devices or other devices that require a lower charge, this model has a trickle power charge mode that is super easy to enact and works perfectly for charging lower power products. Super impressed with this feature and it really does work well on charging my phone as well as my bluetooth device. Have used it for a while now and am more than happy with this purchase.
