    It's nice that you can plug it straight into the wall.

    Got it on sale, wouldn't recommend paying full price for this. I was able to charge my phone one and a half times, but could not charge my bluetooth earbuds, which was really the main reason I bought it.

    I did not particularly like this model. It took too long to charge my phone, it actually never did and although having the AC plug attached to the device was convenient for charging the device, it made it too bulky. I exchanged this product for a slimmer one and something that works quicker.

    Not a good buy. For the size and the price Best buy has better options.

    I bought this to be a charger for both my tablet and my smartphone. It barely charges my smartphone and my tablet doesn't even recognize it. I went with mycharger because I love the one I bought several years ago, but they stopped making that model. Very dissappointed

    I liked this product a lot because I didn't need a cable to charge it just plug it to the wall and it's done But it stopped working after 1 month and I can't get a refund from Best Buy and the company only does refunds when it's bought directly to them

    It did not work after the first charge. I exchanged for the bigger model and it has worked great. Really could have just been the one but they were out of that model when I went to the store.

    Was going on a trip to Greece and needed something to charge my phone on the plane and on my trip. This worked great and charged my phone pretty fast!

    Charges quickly, but not enough to fully charge S7

    I purchased this because it listed itself on the package as a 2.5x charger. The sale price also helped, and i like the fact that it has the wall plug to recharge itself. The package listed it as precharged and it registered as full when i open it. I used it that night to charge my phone. It was able to recharge my galaxy s7 from 40% to full in about 50 minutes, then again from 50% to 80% before it was dead. I fully charged the unit, and the next day I used it when my S7 was down to 15%. It charged it to about 98% before dying in about 75 minutes. If you want a fast charger and don't need more than a 90% recharge one time this is an excellent charger because of the wall plug and faster refill capabilities. If you think you will need to charge your phone on a trip or an event and need it to do what the label says as in a 2.5x recharge do not consider this product. I have tried several others about the same size that will charge my S7 more than 2x to full capacity plus another 30%.

    While I doubt that I could charge my phone 2.5X, it is much better than my previous charger.
