Insignia™ - 15600 mAh Portable Charger - Black/Gray

Purchased this in December on sale, and boy was that a great decision! I never have to worry about running out of power on the go, and can recharge the charger using a quick charger. Its so much easier to just carry this around instead of a whole mess of cords and adapters for each of my portable devices. Charged my cell phone from nearly total power drain + a tablet and still had all charge indicators on the device sitting at full (meaning it hadn't even used 1/4 of its power to get both devices back to maximum capacity). Biggest problem is trying to get it back from family, friends and co-workers whom I have allowed to charge their devices on it from time to time. :) My only regret is that I did not grab it during black friday when it was even cheaper than what i got it for (was still researching/comparing it to other devices). Based on reviews of other similar devices (on this website and others), this seems to be the most reliable charger (in its capacity category) and the quickest to recharge once depleted (in its capacity category). There was one on amazon that had slightly higher capacity than this one and solid reviews, but it was stated to have almost twice the recharge time as this one, and I wanted to have my charger in hand the same day as purchased, so I went with this one (this one also has 3 charging ports, whereas the other one only had two). Great portable charger! Tops off the charge on some of my portable devices better than the chargers they came with! I Highly recommend!

When I travel, I carry too many devices - I admit that. But: what is worse than too many devices is to have all of them run out of power halfway through the trip because there's no time to charge them. I have owned brand named power packs before, and got good service from them. When I found this item at BestBuy, the price was great (about 25% less than the comparable name branded item) so I was skeptical about its performance. Not only did it exceed my expectations, it also exceeded the performance of my old battery pack by about 25% -- meaning rather than just getting one phone charge and one pad charge out of it, I got a second phone charge from it of about 50% of a full charge. That means a lot when you're travelling for 14-18 hours on a long trip and your layovers won't allow you to plug in for any decent period of time to the wall. I completely recommend this item and would buy it again in a heartbeat.

Bought as a backup for hurricane season. After receipt, put it through its paces and charged a number of items including phones, music players and tablets. The charge lasted for hours. Recharged overnight and used again charging many items before the cells finally depleted. Due to the capacity, this item takes overnight to charge. Must use a capable charger as initially attempted recharge using my iphone 6 charger. After an hour, I noticed that the iphone charger was very hot. I unplugged and used a larger charger with more current capability which didn't get hot. Some reviewers noted that the unit only lasted for 1 to 5 recharge cycles after failing, so I'll watch to see that I don't have the same problem.

Purchased this for a camping trip. My friends wanted to go out to the middle of nowhere with no electricity. I bought it for its capacity (15600 mah). I'm a tech junkie that likes to bring lots of gadgets. . Quick Guide Camera batteries= 1000-1500 mah Cell phones= 2000-3000 mah Bluetooth speakers= 1800-4000 mah Three usb ports mean you can chatge three devices at once. This portable charger will charge your peripherals a few times over. Battery life indicator is pretty straight forward represented by four squares (25% each). Portable battery takes some time to charge due to its capacity but planning ahead will save you time (charged it over night prior to trip). You'll be the envy of all your friends towards the end of a long weekend camping trip.

Got this charger since I had lost one of those little one's overseas. The old one would never fully charge my phone and would not charge my tablet. This external charger charged my phone fully 4 times without needing to be recharged itself. Held a charge more than a week also. The unit is a bit heavy and is larger than a portable external hard drive but it does what I need it to do very well.

I bought this product a few weeks ago and I have been using it since. It charges my phone faster than any other portable charger I've tried, and it can charge other phones at the same time. I have not yet tested the "charge a phone six times" advertisement on this, but it most likely will live up to that promise. Great for a day of Pokemon GO Word of Note: It does take awhile to charge, so charge it overnight.

I had the smaller version (the middle model of this series), and when I popped into a Best Buy mobile I saw this version and was torn between going big or staying where I was and I opted for the bigger version. On one or 2 devices, depending on charging frequency this is definitely a good product with its 3 USB ports (I only recommend using 2 devices to charge at a time if the charging requirement is greater than 25% or less on both devices). The battery itself can last 3-5 days on one device depending on frequency of use. Be prepared though if the battery is drained entirely to spend minimum 8 hours for a full length charge. So best to charge this product over night if possible.

For the price I kinda expected it to not be so great. After I receive it it was already charged to like 65-75 percent and I used it to charge my iPhone 6s Plus in about 20-30 min. (With out using the phone of course) it charged my phone from 12% to 89%. Amazing product glad I don't regret buying two. I recommend it if you use your phone a lot for any reason. If u got kids and their in their tablets a lot and you're out and about this is a great product to have. A bit bulky but gets the job done and does its job well.
