Product Overview

This Sun Gold Power 4000W 12V pure sine wave inverter with charger is built for 12V battery setups that need dependable 120V AC power in RVs, trailers, motorhomes, truck campers, and off-grid or backup systems. It is a low-frequency inverter that combines the inverter, built-in battery charger, and automatic transfer switch in one unit, so the power system stays cleaner and easier to manage. When you are running tools, kitchen loads, or the basics in a tight electrical space, an all-in-one inverter charger helps keep the setup organized and predictable.

On the output side, it delivers pure sine wave 120VAC power with bypass mode, rated for 4000W continuous output. It also provides a surge rating of 12,000W for 20 seconds, giving extra headroom for short start-up events and demanding appliances. Typical transfer time is 10ms, which supports smoother switching between AC input and battery power. Output frequency supports 50Hz or 60Hz, and nominal efficiency is listed as greater than 88%.

For 12V systems, the DC input specs are clearly defined. Nominal input voltage is 12V with a minimum start voltage of 10V. The low battery alarm range is 10.5V to 11.0V, and the low battery trip range is selectable from 10.0V to 10.5V. High voltage alarm is 16V, and low battery restart voltage is 13V. Idle consumption is 45W, with power saver mode idle consumption at 18W, which helps reduce waste when the inverter is on but loads are light.

Charging is handled by the integrated AC charger with a 120A ±5A charger rate. AC input voltage is 120VAC, with a selectable AC input range of 90–135VAC or 100–135VAC. Charge settings are selectable based on battery type with adjustable charge current from 0% to 100%, and charging follows a 3-step intelligent battery charging method. Overcharge protection shutdown is specified at 15.7V. Control and visibility are straightforward through the LCD display for system monitoring, and remote control plus a BTS cable are included. This unit also supports automatic generator start when battery voltage is low and lets you select AC or battery priority via switch. A GFCI socket is included for enhanced safety.

  • Generator-backed builds using automatic generator start when battery voltage is low
  • Installations where lower standby draw matters with 18W power saver mode idle consumption

Why This One Makes Sense

This inverter charger is a solid fit when you need high-capacity 120VAC power from a 12V battery system and you want the charging and transfer functions built in. You get 4000W continuous pure sine output with bypass mode, plus 12,000W surge for 20 seconds for short start-up events. Typical 10ms transfer time helps keep the system switching sources smoothly, and AC or battery priority selection via switch keeps the operating behavior aligned with how the rig or site is set up. The integrated 120A ±5A charger with selectable AC input range and 0%–100% adjustable charging current supports better control over battery charging, while the 18W power saver idle consumption helps reduce standby waste. Add the included remote control and BTS cable, LCD monitoring, automatic generator start support, and a built-in GFCI socket, and it fits mobile and off-grid systems that need dependable power without extra boxes.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them. My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy. The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties. The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues. I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet. When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know). The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room. I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.

Simple, durable, and a great buy for active dogs. 🐕🎾
Size: 3 PCS, Size: 3 PCS
These are exactly what I look for in a simple dog toy. The balls are made from a durable rubber material that feels sturdy enough for regular play, while still having enough give to be safe and comfortable for dogs to carry in their mouths. They bounce well, are easy to throw, and have held up nicely during play sessions. I also like the bright colors. The orange, blue, and yellow make them easy to spot in grass, at the park, or in the backyard, which means less time searching and more time playing. The textured surface gives dogs something easy to grip, and the size works well for medium to larger dogs. They feel much more substantial than the bargain-bin tennis balls that seem to fall apart after a few outings. Perhaps the best part is the value. For the price, getting three durable rubber balls is a great deal. Dog toys can get expensive quickly, and this set provides a lot of entertainment without costing much. Overall, these are durable, colorful, fun, and appear safe for everyday play. Combined with the very reasonable price point, they represent an excellent value for dog owners.

Really rough and tough and able to endure some pretty gnarly chewing!
Size: 3 PCS
These are some really stout, durable, tuff balls that are designed to endure some pretty rough chewers! They don't have the best bounce capability. If you throw one down onto pavement, it's not going to bounce back to you the same way a tennis ball would. It's probably got about half the comeback as a tennis ball, so to get the same return you would have to throw it about twice as hard as you would a tennis ball. But the balls were not designed to bounce around, they were designed to throw to your dog and play fetch and be able to endure some pretty rough gnawing and chewing while your dog is returning the ball to you. I have a 30 lb westie, and these balls are pretty much the perfect size for his medium size chomper. He is able to pick the ball up and carry it around with great ease, he is able to catch it in the air with no problem. Now my little 12 lb chihuahua is not able to carry the ball around, his mouth is just too small too be able to pick the ball up. In my opinion the asking price for these balls is really fair and reasonable! I would absolutely recommend this product to my friends and family!!

Nice quality balls for heavy chewers that are easy to clean
Size: 3 PCS, Size: 3 PCS
Nice quality heavy duty balls for strong chewers. I love that these don't have those holes in them that so many balls do that collect grossness and dirt. These are solid and easy to clean. My 9 week old puppy can pick them up and carry them around from the side of her mouth. But the next door 5 year old Labrador is obsessed with them. But then again he is obsessed with balls in general. I just like that these seem to hold less gunk than the others we give him to play with frequently. And they seem to have help up to his chewing just fine. They are reasonably priced for a set of 3 and the colors are nice and visible in the grass which is important. I would be careful to pick them up before mowing the lawn because these are solid and somewhat heavy and I could definitely see a mower just slinging them through a window or off your siding. Overall a nice set of balls that are easy for a human to throw and fit the hand comfortably. They are easy to clean and they are apparently appreciated by the local retrieval expert next door.
