    I have many chargers. Most of them are big & bulky and a pain to have in my pocket. Most if the time I need a charger, I’m on the go, so this is the perfect size charger. I got this charger for my son, who is traveling w his school, because he had the same complaints, “our chargers are too big snd too heavy”. After trying this charger, he said, “it’s great, it fits in my sweat shorts and doesnt pull them down, and it can charge my phone and my “ears” (airpods) at the same time!” Great product. Definitely recommend it!

    This charger is great! You can charge multiple items at once and the size of the battery is awesome (see attached photos). It is about the same size of my phone, so it fits perfectly in a purse, etc. I have purchased previous portable chargers and the I must say I prefer to use this one! I would definitely recommend purchasing this charger.

    Works fine. 10000 mAh is not too big and heavy and not too small (2000 or 5000) for my needs. I usually use a cable to charge my devices but wireless is really convenient (and it works fine) when it is inconvenient to pull out cables (e.g., during a meeting and such).

    I'm really happy with this portable charger, it's fast and I like that it has the LCD display to show how much charge is left on it. I'm very glad I purchased it and it'll be really good for whenever the power goes out so I can keep my cell phone charged.

    It does the job... mostly. It has enough in a charge for two charges of my iPhone 13 Pro. However, right out of the box, it's had some weird behavior. There's an LED screen on the product that has been flashing. It charges at a decent speed, but it's nothing groundbreaking. Perfectly acceptable, but not gonna blow your mind.

    Perfect size and weight for portability. Plenty of power to recharge phones. Wireless charging works flawlessly. The only negative is the insanely short power cord - barely a foot long.

    Great power bank. It has a lot of charging power for its weight and size. Comes in at half a pound and easily fits in my pocket. I found myself using the wireless charging option more than I thought since it charges through my phone cases. It’s a nice touch that sets it apart from other power banks.

    Since my iPhone cannot be charged using a lighting cable this has been very easy to use. I like the green LED that shows the unit is charging the phone wirelessly. Having the percentage show is very useful

    Perfect, slim and light little portable charger! Love that I can use cables to charge or just lay my phone on it for a wireless charge! (I do have to remember to turn on the power button if I am going to lay my phone on it.) Fast and easy!

    It’s great!! It’s perfect for your vehicle, you can send it to the backseat for your passengers/kids and there are no cords! It is strong enough to charge while still using your phone. It’s great!

    Great Power Bank for the money

    I like to carry an external power bank in my truck just in case my phone runs low. This one has Micro-USB, USB Type A and USB Type C ports on it which is really handy since so many of the devices these days have different ports. I have it connected to a multi port charge in the truck with a cable that has both USB C and A ends and it's really handy as it charges while I am driving and then the small cable I use goes with me if I take the charger out of the truck and can charge phone when needed. The value was good and I really like the charge percentage indicator on this charger as well.
