Portable Charger, 15000mAh 18W PD QC3.0 Power Bank Portable Battery Charger, 4 Output Dual Input Portable Phone Charger Battery Pack with Built-in Wall Plug,Type-C 2 Cables Compatible for iPhone etc

I previously owned two other power banks that have a built-in lightning cable, and I've learned these built-in charging cables don't last long, because of the way these cables are attached to the main housing, causing them to bend when they are being used. The frequent bending of the cables makes these cables stop working. So I normally don't use these built-in cables unless I forget to bring other cables along, and I'll make sure they are not bent when I use them.Even with the built-in AC plug, this power bank is still pretty compact given it has a 15000mAh capacity. I tested it with a USB Digital Tester. This power bank could output a total of 44Wh before it ran out of juice, about 80% efficiency of its advertized 55Wh, which is expected for any power bank. It is also the best of its class in terms of charging capability: a USB-C with 18W Power Delivery as well as a QC3.0 USB port. The built-in AC plug is a bonus.I bought my second one this morning when its price becomes $33.56.

I was very excited about this battery bank. I already own about 6-7 battery banks. I really like battery banks with built in wall charging prongs and built charging cables so when I saw this one I was really excited about it. I even waited for it to get some reviews before purchasing. I finally pulled the plug and it arrived damaged. It would not take a charge when plugged into a wall outlet. It did, however, take a charge using the type c slot charging port. The prongs were one of the biggest selling points for me so I was very disappointed. I strongly considered exchanging it and trying to give this brand another shot, but I needed it for work and didn't want to risk getting another faulty product or possibly a product that would break after a short time. I ultimately ended up going with a ravpower battery bank that was on sale. It does not have built in wall charging prongs or cables but it was half the price and the brand is extremely reliable. I have two from that brand that are 5+ years old that are still going strong. If I decide to give this another try I will update my review.

I had one of the “solar rechargeable power banks” and discovered it would take a week of sitting in the sun to recharge it and I needed to also carry around a USB adapter and a lightning cable to use it... and when it broke only months after buying it, I shopped around for a new power bank with updated criteria:1) not solar, since the panels are too small to make it worthwhile and it’s just another thing to break2) built in 120V plug so I’m not having to carry around a USB adapter.3) Built in lightning cable so i don’t have to carry around a cord4) Power indicator so a I know how much charge is left in it.This one fit the bill perfectly and after a few weeks has functioned flawlessly. So far so good, would recommend at this point!

Didn’t even last one day. Sometimes it would work. Sometimes it wouldn’t. So very, very disappointing. To make matters worse, customer service didn’t even respond to my emails. I can handle a product not working. It happens. But for customer service to not respond. There’s your one-star. Failed product; failed customer service.

I had a previous power bank that was similar but used the flat design, about the size of a cell phone, that also had a fold-out plug for 110V AC charging. I really like the concept of a self charging powerbank that has built in lightning wire and can also provide a USB port for charging when power is available.I was curious to know if the USB port would allow me to charge my notebook computer (LG Gram, with USB-C charging). When I plugged it in, I could to following message (see image). I don't speak that language and did not click on the "OK" button. I wonder if anyone can translate or if the manufacturer can tell me if this device would be able to change a notebook computer?overall seems like a nice design. if the lightning cable stops working it will be a disappointment because there is now way to replace it.the unit is a little heavier than i expected, but it says it has 15000 mAh, which is on the high end for power banks (good) so maybe the weight should be expected.I've seen some that also include a small LED to use as an emergency flashlight, that would have been nice but I didn't think it was that important.

I absolutely love this because it is so compact and you don’t need to bring anything with you. It has the wall plug and some charging wires. There is additional places to charge if you are not using a micro usb or a Apple lightning wire.It displays the percentage of battery right on it. It did not come fully charged - so make sure you plug it in before your next outing.It is a little heavy- which is to be expected since there is a good sized batteryWhen you plugging in, it actually holds well to the wall.The wires l that are included are a little smaller - but they are actually a good length for basic charging. I like that you can charge many things at once.It is about the size (and weight ) of a Mac charging block- just no long wires going either way.It is great for traveling because it is so compact.Totally reccomend because of its size, charging ability and usefulness.
