Solar Power Bank Portable Charger RAVPower 15000mAh Outdoor Dual USB External Battery Pack Power Pack and Flashlight (IPX4 Splashproof, Dustproof, Solar Panel Charging, DC5V/2A Input)

I purchased this battery pack almost a year ago and its still going strong. Its endured my children dropping it, multiple charge cycles and near constant use and it has held up wonderfully. It seems to charge my devices faster than many of my AC USB adapters and I like having the built in light when I need it as well.My two favorite features are:1: Simultaneous device charging. My wife and I can both charge our devices at the same time and its so easy to take with us places you never have to worry about losing power somewhere.2: This thing holds a serious amount of mAh.. Which is to say, you charge it once and it will charge your devices SEVERAL times before you have to charge up the battery pack again. This is ideal for camping or travelling where you may not have access or time to charge your devices at a wall outlet.My experiences with this battery pack has given me confidence in the other products RavPower offers.

I absolutely love my RavPower! I have had it and used it daily for about 2 months. You have to charge it via USB to computer rather than USB to wall adapter, which gets inconvenient sometimes. It takes about 8 hours to fully charge, however I get approximately 7 full charges to my iPhone 6.The RavPower charges my devices lightning fast, a believe a bit faster than direct charging from the wall. The fact that it has 3 USB ports for simultaneous charging is also handy when taking road trips or going to music festivals where everyone wants to charge their phone at once. I find myself charging the RavPower overnight on Sundays, and the juice will last me through the week without plugging my phone into anything else. It's great to have a charging station on the go and never be troubled with the thought of losing power when you need it the most!The design is a bit bulky, but the longevity and power it provides compensates for that. I had a cheaper MaxBoost portable charger, and this one blows it out of the water! Highly recommended product!

If you are on the go and tired of you phone dying this is the ticket. Once charged this battery kicks butt! I can charge phones for days on a single charge. In fact this charges my phone faster than apple’s wall charger. So we tend forget to charge things, we just leave this sitting where it gets sunlight and it’s charged and ready! Never dead! I love this, and highly recommend it. On con would be the size would be nicer if it was a little smaller, but not a deal breaker for me.

I have had the RavPower Xtreme 18200mAh for over two weeks now. This battery is amazing! I thought it wasn't going to charge my Apple Ipad 4th Gen but I was so wrong. Ipad went from almost 0 to 100 in a matter of hours, plus the battery still had plenty of juice left! The size of the battery is a tad on the large side but well worth it. Fits perfectly in my computer bag. Anyway, took it on a trip to Salt Lake City for a week and my phone and Ipad stayed charged the whole time there. I originally bought this battery for my camping trips with the family. Even camping the kids need thier cell phones charged. Looks like i'll be going in two weeks camping with the family to Southern California and I know it will live up to its ratings.

Awesome power delivery in a small package. Just plug your device in and it does the rest. Shuts off when done. 3 ports to charge your devices. Digital read out to display how much charge is left and a built in flashlight too! No charger came with the device but I charge it with a wall mount USB charger that I have here and it charges the battery pack overnight. Small form factor ( about the size of an average "smart" cellphone ). Easy to stick in your pocket or purse. A great thing to have if you are on the go but not near a place to charge your phone, digital camera or whatever.

I have a Galaxy S5 and I was able to charge my phone 5 times (starting at 20% to 100%) before needing to recharge this battery. Hope this helps give you some realistic information. Although, the user manual recommends recharging this battery bank once it hits 50%, but for the life of me I can't figure out why. The whole point of using lithium ion batteries is that, unlike alkaline or wet cell batteries, you should be able to fully discharge them without damaging them. Yet, it still recommends recharging this device once it hits 50%. If I were to do that, I would only get half the results I've gotten so far. Keep that in mind, and if you're wondering, that's the only reason I brought it down one star.

I love this battery pack/charger. By the end of the day, my phone battery is usually pretty drained. This unit will recharge it quickly even while it's still in use. It's got 3 charging ports, which is perfect when you've got a few things to charge. On vacation, we used it to charge 3 phones at once, and it performed beautifully.It holds its own charge beautifully, and can charge your items while it's recharging. It will bring my phone from 30% to a full charge in a short time, and its indicator shows only 2% depleted.The only down side for some folks may be the size. It's too big to carry in a small purse or pocket .better suited for a larger bag or tote.

The display lights up but shows zero numbers so I have no idea how much charge if any is in the battery pack. It arrived in this condition. So I decided to test it and plugged in a Note 4. It does seem to charge but I have no idea how long or if the unit will even hold up due to not being able to see how much battery it really has.Update!!!! The seller sent me a new unit to replace the one that had issues. The seller contacted me right away and shipping was fast. I tested out the replacement unit and everything works great this far. I originally put as one star will now change to three.
