Comments about Brunton Sustain Portable Power Device:

I'm still in the testing phase with this and the device appears to be well built and works as specified but additional accessories are needed to make it really useful:

1) it needs a 12v charging cable so that you can charge it off of the 12v outlet in a car. Making one of these cables is proving difficult because the tips available from Radio Shack are too short to make a solid contact due to the rubber protection around the battery.
2) it needs a 12v female socket to allow you to attach devices which only have a cigarette lighter adaptor. e.g. iPad charger, AA charger, small AC inverter.

Some other notes:
- The AC adapter is pretty beefy and puts out 31W. I haven't had a chance to test it yet but at that rate it should be able to charge the whole battery in about 2.5 hours.
- Since it is a portable device and you may want to carry the charger so that you can charge it in the field, it might be nice if the charger had plug blades that folded in and a cord management system.
- The battery is 73Wh this means that trying to charge it with the typical 5W fold up solar panel will take at the very least 15 hours. If you are doing a major through hike this might not be feasible. You can probably get an hour or so during lunch but depending on your usage you might slowly discharge it.
- The USB port doesn't provide enough power to charge an iPad whose adaptor is 10W which is substantially higher than the its USB port is rated for. It won't even charge it in a slow mode. To work around this you need to fabricate a female 12 socket and then you can use something like a Griffin PowerJolt.
- It does seem to provide plenty of power to charge an iPhone but it may not be quite as fast as with the iPhone's 5W wall adaptor.
- All the other USB gadgets that I have tested so far have charged at the normal speed.
- It does seem to charge a Yaesu VX-8R Ham radio easily
- The weight listed in the specs appears to be the be the weight of the box with all the accessories. The battery itself only weighs: 647g and the AC adaptor weighs 147g. The cables will be extra.

Some additional tests that I intend to run and post in an updated review:
1) How fast does it charge off of the AC adaptor?
2) How fast does it charge off of a 5W solar panel?
3) Given virtually unlimited power (e.g. 100W 12V solar panel) how fast can it charge? Is the charge rate limited by the AC adaptor?
4) How fast does it charge an iPhone in comparison to the iPhone's 5W charger?

Comments about Brunton Sustain Portable Power Device:

I own several smart batteries (Goal0 Sherpa 120 x4), and folding solar panels (1x 26W Brunton, 2x 12W Sunlinq, 1x 5V1A USB Brunton). My usage is to power 110V chargers & USB devices. Included are camcorder, camera, Kindle, phones, GPS, small laptop, camp lights, flashlights, headlamps, Steripen. I do this for motorcycle camping. This battery was purchased to downsize to a smaller & lighter battery for backpacking.Received product in mail, charger was DOA. I measured it with a DMM; totally dead. Crafted charging adapter plug and charged it from 12V 10A supply (Goal0 Sherpa 120 battery x4=480Wh). This battery would only charge up to 80% after 10 hours! (according to the display). Discharged battery with 4x LED lamps of 3W each (12W @ 12V @ 1A) 73Wh should last about 6 hours & it should be able to supply this at 1A. Lasted less than 3 hours before battery turned off. Cycled the charging/discharging 4 times hoping this would break in the battery. Charge still not total, capacity still bad. Took it back to store[...]I ordered another battery[...]received it. Power supply works this time! Battery acts the same as the last one, it won't charge fully after more than 10 hours with their charger. At 1A drain this battery also has about half the capacity that is advertised. At first I figured maybe the battery gauge design was just not accurate. Now I'm thinking it is that, plus their Wh ratings may be at the USB 600mA rate. Batteries will normally have less Wh & Ah ratings at different discharge rates. Geeze, 12V@1A =12W is not much of a load for this battery. It should give better than 35Wh of 73Wh for the premium cost and weight. I also noticed in both instruction manuals, that they are a bit confused about USB. On REI I believe it propagated and implies it can be charged with USB. It can not. The manual also mentions an auto shutoff and red LED when it is on. This is on their other products, not this one. Very disappointing for a potentially useful product made by a very good company.After more testing, I may return this battery also. For this cost, it is not worth the half capacity. I'll probably just use a Sherpa 120 or buy a Sherpa 50 (50Wh) for less weight in my backpack.
