So basically without a USB connection, or electricity for that matter you would be SOL after 80 cycles, correct?

Hi there, D. Noble! As all CamelBak products, this one is also very reliable and made to last. A fully charged All Clear™ will last around 80 cycles, each cycle will provide you around 600ml. 600*80/100 = 48L per charge. If you go camping, well... let's say you can get a decent amount of purified water in one charge. The All Clear™ also features one accessory, a pre-filter which really mades the difference when getting water from rivers or streams with high amounts of sediment. Hope you make the right choice!

unless you have one of those USB Back up battery for when you don't have electricity. You'd still need to plug it into a power source. Doesn't have a stand alone battery.

It does power down after a period of inactivity. If you request information there is a 1 to 2 second delay then it responds. It still uses an external power supply as opposed to the trend of USB 5 volt power.

Nope. It works without any external power source and yes it works just fine.

It will provide power without being connected to a PC and can charge some items, however devices that require higher current to properly charge (tablets, etc) might be a problem.

I only see a USB connection. It can also be charged by the crank or by solar. Solar is being reported as weak, but ours is in the window all day long, so we have significantly more power in ours. The battery is a CR 123A. The crank works well and it is pretty sturdy.

Experimentation tells me that the answer is NO. My experience with bus powered USB hubs has been problematic. Commonly you get a "power fault" on one or more of the devices involved and restoration is very difficult without rebooting (ugh).

You can use the device without the solar panels connected. The panels are just used to charge the device.

Yes. Our setup is consists of the charging panel, an RV battery, and a cigarette-outlet style inverter. With that, we had enough electricity to power our little pick-up camper AND charge cell phones and my laptop on a 3-day camping trip. Without the battery, though, I think you'd pretty much have a trickle charge that would take FOREVER to power up a laptop.

That is a good question. I'm not exactly sure, but I don't think so because it usually shuts off all features when it is "connected to USB"

hey tom yes if you plug it into the wall you will have unlimited usage as long as you have it on the docking station it will not charge on the usb if its in use you than only have a hour or so depending how many pictures you scan when its on the docking station plugged in you can go as long as you want its very good and fast.hope this helps dave

I leave mine plugged in without batteries with no ill effects so far. But am concerned about power surgesrecently. They have reset my computer even with line conditioning and battery backup. Prob. from on/off/on cycle.

If there is, it's by no means accessible to the average consumer. The clear answer is no. You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

I have left mine connected without being plugged in for a few hours without a problem. But I don't know about permanently I have never done that.
1551469
Yes, that is exactly what I do. Even though my laptop has a usb port, I did not want to tie it up just to get power from it.

It works without power supply when attached devices have little power consumption but peripherals such as an external hard drive that draws power from the port requires the added boost of the external power supply.

The card is not a battery. It connects to your laptop through the USB and then to the phone so you can always charge without a cable
