Rated 3 out of 5 stars
Works, but lacking
As a basic battery bank / charger this works fine. It will fully charge a larger device like the Samsung Note 8. The Digital read out of battery percentage is also nice. Fairly thin, and doesn't get overly hot when in use. Things I don't like: No USB C port even though the picture on Best Buys Website shows a USB C port. This guy only has USB Type A for charging your device, and MicroUSB to charge the battery bank. It doesn't work with the Qualcomm Wireless fast charging specification, so although it will wirelessly charge your device, it's very slow. It won't charge smaller wireless devices like a smatwatch. Guessing its because they don't pull enough watts. It starts charging, but the bank eventually turns itself off because its not detecting enough wattage being pulled. Overall, for the price I would just stick with normal battery banks as this is very slow and doesn't support the newest connection available.

It works but not great
This works but is not great but some of that isn't the products fault which is why I am giving it an average score of 3 stars instead of a negative rating. The biggest problem with this product is the wireless charging feature. It works but it takes forever to charge and uses a lot more battery than if it is plugged in. For the speed, that's what happens with wireless charging but this is slower than most. I have an Insignia wireless charger and it works great, especially for a store brand. It takes twice as long to charge my phone than if I plugged it in but that is expected. This wireless charging doubles that charge time on top of the already 50% charging speed. The other main issue is that the 4,000 mAh isn't very accurate in reality. If you have a phone that has a 3,600 mAh battery, you would expect that you could charge it fully from this charger but that isn't the case, even when plugged into it. If you plug into the unit, you might end up getting about 3,500 mAh from it before it runs out of power. If you use the wireless charging you may get about 1,000 mAh before it runs out of power. I was very disappointed with the performance of this but did understand some of the issues with the wireless performance before I purchased it but still expected it to be a lot better than it was. I ended up returning it and getting the Tzumi - PocketJuice 15,000 mAh charger instead. This one doesn't have the wireless feature but is almost 4 times the battery and works sooo much better and only cost $18 more. If you need the wireless charging feature I would recommend going with a much larger battery so you can at least charge your phone once completely before it dies. That would mean you need about 4 times the size of your phones battery if you want to charge wirelessly or about 1.5-2 times the size to charge it through the USB port. Personally, I like the larger battery pack with more power over the wireless feature. I don't need the wireless so having more power and getting it more efficiently is better for me.

This device is OK...
I wish it charged fast wirelessly like my plugged in unit on the nightstand. Also, it will fully charge my iPhone 8 about 1..5 times, not twice. But it is ok. I'm a little annoyed with the adhesive that was on the sticker over the display so it looks like it is showing a number in the packaging (for marketing), because it won't come off. Used Goo-Gone and the whole display seems a little cloudy now. But this still works.
