I drive truck and was wondering how long the battery will last running 300w inverter running a laptop External Hard Drive And External blue ray

The battery in packs like this have a rating like "18 amp-hour" hinting it can supply 1 amp (at 12V) for 18 hours, or 2 amps for 9 hours, etc. Running the inverter will use a bit of energy itself, otherwise it just transforms the power to 120V where something needing 1 amp at 120V needs 10 amps at 12V (since both of those =120watts). I don't know exactly what your blue ray player or such uses, so the only way to know for sure is to measure them in use with something like the "kill-a-watt" meter. I doubt they need much energy, so if it's under 1 amp at 120V the battery should last at least 2 hours, but that's a guess.

I have two battery rated at 1200 CCA. I've been able to run every power tool on my truck, ie, vacuum pump, microwave, chop saw, etc. Please refer to OHMS Law for your specific needs. This is an awesome invertor.

I have had this battery for over a year now. It use to stay charged for approximately 2 hours under heavy use. One thing I have done lately that has actually extended the charge to 30 - 45 minutes longer, is replace the old hard drive with a solid state hard drive. This has also breathed new life into the laptop to make it like a new one again. It is twice as fast after I added the maximum RAM and solid state drive. Cheaper than buying a new laptop.

I use a 425 Watt DC/AC inverter hooked up to my car battery. No issues at all. Only takes a few minutes to inflate.

Dunno if this one will makeyour truck faster, which kind of batterie areu using right now? If u r still on 6/7cell lithiumion go and switch to 2s lipo packs, for thoseu will need a different loader than the standart one, but buying a lipo loader and 2 lipo packs realyisworth it cause with those u will drive for like 45 minutes, charge them in 1 hour and have like 150% speed and power.GreetingsRoger

I am using mine to keep the battery charged on my truck which sits idle a lot. A lot of factors are involved. How sunny is the location how much power the gate opener requires etc. You might want to go to something a little larger than 10W

I put batteries in mine 3 months ago. I've only pulled my trailer 3,000 miles, that's about 60 hours. Batteries are still working fine. Keep in mind that the monitor has auto shut-off if it doesn't feel vibrations of the road, I've had mine shut down while stuck in traffic jams. The unit also comes with a cigarette lighter plug.

I don't know how long the battery last. I would assume it depends on how much you use it. How many times do you un hitch the trailer and hook it back up. It is rare for me to keep un hitching my trailer. I do it maybe twice in a use. I love the Iball. It would take me half a dozen times of backing up the trailer without it.

I can only tell you what I did. I have a 400W inverter and a 12V car battery. I use this in my small horse barn that I wired for three bulbs and an outlet. There are 3 small watt bulbs. The panel keeps the battery at full charge with no problem. I don't use the electric all the time, and for only short periods when I do, so I don't know how long the charge will last.

This Go Power unit can take 1500 Watts on a constant basis, and surge (briefly) to 3000 watts. I have tested this unit with a large frost free refrigerator, and a small 5CF freezer, connected to a 4 deep cell battery bank. This unit ran flawlessly and even after 36 hours, I still had over 65% battery power left! A good solid unit! I spent a lot of time researching inverters, before I decided on this one. Glad I did.

Hi there. For camping. and sleeping on the back of my pickup truck. Im using a 100 watt solar pannel connected to a 125 mah battery with a 1000 watt power inverter. I also use a 200 watt heater( smallest I could find) so I wont drain the battery so quick. in other words this one can be use as well in a setu up like mine or if you want to use it in your car battery you would need to connect the 1000 watt amp DIRECTLY from the car battery. DONOT connect it of cigaret outlet. it will blow the fuse since those dont allow to go up to 1000 watts. any questions just ask :)

So far, its been working great. My husband uses his in his truck out at work. He LOVES it. He only uses it when his truck is running and always unplugs when he is finished. I have heard that it uses a lot of power and can drain your battery but so far he hasn't had any problems.

I used a standard car battrery and it ran a radio 2 40 watt lamps for days before needing a charge. Make sure you dont get poitive and negitive mixed up. It killed my inverter dead.

The inverter is a 3500 W. 4 1500 W equals 6000 w. That would mean you would need 2. I use this inverter on my boat. It runs a household refrigerator of approximately 1800 W. The best thing about this inverter is that it will shut down if it is back fed. Since I switch from AC to DC this feature is extremely valuable. I would recommend this inverter because I have tried Xanax and I burnt out 4 them. As far as the amount of battery you need it all depends on how long you going to run the unit.

I tend to keep mine on power save, it seems to last pretty well. I'm not sure and exact answer on a number but several hours.

I have only tried mine for temporary emergency power and did not ground ( not saying this is right because I don't know if necessary or not), but inverter ideally would have short cables and therefore be close to vehicle ( ideally 3 ft or so) otherwise will have considerable power drop. Then can use long extension cord.

I installed this inverter in my travel trailer mounted more or less just above the axles. Last year we drove about 10,000 miles with the trailer including some dirt roads and the inverter is still working fine. So far we have no complaints. Stephan
