Sounds cool. How long would a fully charged battery last?

It depends on your energy consumption.

The only issue I have is that it uses lithium ion. When you finally use it years down the line, you may find the battery not holding charge, or the capacity is much less than when it was new.

not long.
I'm running 45 watts at my house and it doesn't last long at all.

You realize this is a 20 watt solar panel, a small battery, a cheap/small power inverter, and a small case. Less than $100 and you can build your own. For this price you can build a fold out 200w system, 10x the power. I would like a bigger system that I can use to run my future shop building, and as an emergency solar options to power the well pump. But I need a $1000 power inverter to supply enough watts at 220v for the well pump.

Uhh..Of all the types of batteries you can expect to find reasonably priced Li-ion is the best. Most- all solar battery systems use much lower energy dense batteries with worse life expectancy.

It depends on what you have hooked up to it. I can run a fan off of it but the charge gets used quickly. If you are looking to charge in the day and use at night to charge phone and power some rechargeable batteries to use in other devices that is ideal along with the fact that it is portable with battery with AC and DC out to use with standard plug, car outlet, or USB I cannot complain.

Agreed. After all we are all dependent on electricity for one reason or another. It does allow you to add a solar panel but sure if you can build your own go for it. I know very few people who have the tools or the time.

Density is not the issue. Lithium-ion batteries suffer from aging so in a couple of years, you can expect reduced capacity, even if you never use the battery. I have li-ion batteries that charge to 4.2v when new, but now only charge to 3.6v at most. I would not want to pay hundreds of dollars just to end up with a dud when I need it the most.

Interesting "deal". I kinda see this as a 40000mAh USB power pack with a decent sized solar panels and 12VDC/120VAC out (145 Wh / 3.6~3.7V = 40000mAh "equivalent" when compared to USB Li-Ion battery packs rated at mAh @3.6~3.7V). It's not really for continuous discharge/use unless you're using up to 20~30W devices while solar charging or <15W without solar charging. It seems handy for field or outdoors use.

As for building something similar for under $100, here's my cost breakdown using retail parts:

20W solar panel: $55~65 at Amazon for a 20W mono-crystalline panel that's double the size, or $80 for (2) 10W panels. The briefcase has a handy folding 2-panel design.

145 Wh battery: $73~$150, at $5~10 per 18650, ~10Wh Li-Ion cell depending on source: fasttech or reputable); under $30 if you choose a heavier (6.7 lb), slower max. charge/discharge rate, 12V 12Ah sealed lead acid (SLA)

charger and protection circuit, 5V, 12V, 120VAC converter: "depends", $50 and a lot of DIY and wiring, and possible a number of questionable eBay/China parts.

$420 is quite reasonable. It's pretty compact at 15.8" x 12.3" x 4.3" and 12 lbs even with the impact-resist and waterproof briefcase. It's cool to know that something like this exists. Too bad (but not surprisingly) it doesn't have replaceable/expandable battery, as I bet there's room to fit double the batteries inside.

And LOL at the customer Q&A section. I bet someone wants to run their whole house with this briefcase during a power outage. P.S.: per wikipedia and CNet, the PS3 slim (4th and 5th generation) draws 70~96W during gameplay or movie playback, less than half the original fat PS3. Add a 24~32" LED TV and you should get around 1 hour of gaming.
