I can only tell you the power supply has been sitting charged up on my desk for over a month and it looks like it is still at or near full charge. My guess is, you won't have any problem for an 8 day trip.

I bought this for my wife and I think the longest she has had it in her purse without using it was about 3 weeks. When she went to use it again it had enough charge to keep her iphone 4 going until she was home. Then she used it for the next several hours because she didn't want to get up and look for the ever elusive iPhone cable and adapter. She's not diligent about keeping it charged and it has always had enough charge when she needed it. We've got a satellite TV receiver in the kitchen with a usb port and out of cconvenience she uses that port to keep it charged. From that port it takes about 30 minutes for a full charge. I'm sure it would be faster with an ac adapter.

No, you won't be able to last 4 days, because this device will only charge your phone for around 2.5 times. In fact, I have the 20,000 mah variant of this device, and I could sell you it for a huge discount on my eBay account. My eBay profile is ataya55, and when you message me on there, I can list it at a price we agree on. Sounds good?

This has a great battery life. I only charge this once a week sometimes twice with heavy use. I would say a solid 8hrs give or take

It depends on the device you're charging and how drained it is. However, for standard reference, we generally get 3 charges out of it with an iPhone 5S when it's down to about 20%.

Not sure I understand the question. I use it to recharge my device, not as a supplementary power supply.Mine holds a charge for about 3-4 weeks.It charges my Iphone 1-1.5 times on one charge.

It will charge it but much longer than a regular charger that came with your phone, approx 8 hours

My daughter used it to charge her iPhone on a Costa Rica trip and my wife used it on a four day horseback riding adventure, they were both impressed with it and amused at how others were asking to use it. I am no expert but I believe as long as you can plug it into a USB port it will work. Keep in mind, they both said you really need to keep it in the sun to get it to charge adequately! but worked like a charm. good luck, Steve

I may not be the best test case for this but I can say it lasted me the entire week on vacation and had 20% of the battery life left after 7 days. I probably used it much less than the average user so I am sure your results will vary depending on usage. I would guess it would last at least the entire day under normal use.

It should last up to ten days...if you have a computer, it will charge off the computer battery with the little gray cord

It's very durable, I've dropped mine several of times and it protects my phone. The charge seems to last a little longer than the iPhone battery. So if their both charged up it has lasted me the entire day with a lot of use. It depends on how much you use it. If you don't use it much the charge can last 1.5-2 days almost. I have a 4s, not sure of the 5s model.

I also bought this for a couple and it's worked perfectly. Unless you are going on an extended trip, When you travel you don't even need to bring the charger since it holds for at least 7-10 days on a single charge. At home, one if uses the base with uv cleaner and the other without. We love it.

It will vary.. If you are not charging a phone, and the USB supply (you will need to provide this) is large enough in about 2 hours. If you run it down about 4 hours... all depends on your usb power supply.

The charging last almost a week for me, using MOSTLY twice a day (occasionally I only use once). My son and I use different head attachments and the charge only lasts around 3 days, but it's being used 4 times a day.

The Anker Pro can charge a laptop. It's a bit bulky to carry around. So while it could charge your iPhone 8 - 10 times, I'd recommend a smaller battery. 8000 - 12000mah is more than enough and more portable.

No, it is not waterproof. Yes it is durable enough to bring on a long trip. However, you're likely better served by bringing a decent rechargeable battery. I own the Nomad 7 and Guide 10 combo. Bringing a USB rechargeable battery or two is cheaper, lighter, and takes up less bag space. Anker products offer amazing options (as a single example for half the cost of this unit you can get 20,000 mAh which is enough to charge an iPhone 6 seven times). If you are concerned with size and/or weight, and have USB chargeable items just get a battery. I can get away with 5,000 mAh for a three day trip using USB powered speakers, goal zero flashlight, and keeping my phone variable for pictures, video and music. No, it is not waterproof.
