Things To Consider before buying the Best Electronic Ear Muffs for Shooting

The amount of power that a generator can put out is measured in watts. The wattage of the generator is probably its most important feature. It tracks how many devices it can support or charge. The more wattage a generator is rated for, and the more outlets it has, the more it can do. It is important to select a generator with the appropriate level of wattage. If it is too low, you won’t be able to power everything you want. If it is too high, then you are overspending because you won’t be able to use the extra wattage. A model with more watts is nearly always more expensive, so there is no point buying unnecessary power. Read the instructions of your devices to learn how many watts they need, and use that to make a decision about which level of power is suitable for your needs.



Once you get past wattage, you can separate generators based on their extra features. For example, some generators are more portable because they have better wheels or easier to use handles. Others are equipped with more outlets so they can support a greater variety of items. Still others are especially light or compact so that they are easier to transport. All of these can be useful, but they should never override wattage. You can use these extra features to distinguish between different models of generator that have the right price range and watt output. They play a role in your user experience, but are not directly related to power generation. These are for convenience and comfort.


Durability deserves its own consideration because it makes a big difference in how much value you get out of your generator. An generator that you will use when camping and outdoors with an RV has to be tough. You are likely to bring it into potentially rough terrain, it might encounter bumps and drops, and it could get wet if there is rain or other water. No generator can take a ton of damage from any of these sources and still work at peak ability, but the tougher it is, the longer it will last. You should expect your generator to last at least a few years with ordinary use. Anything past that is a nice bonus. The less you jostle it, the less you have to worry about damage. Most generators should be at about the same toughness, so you really need to be on the lookout for ones that are made with poor materials.


Efficiency refers to how well a generator converts fuel into energy. Most generators run on gas. If the generator is efficient, then you won’t need to buy as much gas, which will save you a lot of money in the long run. The cost of fuel is the biggest overhead cost that you need to deal with when you have a generator. Some newer generators now have solar panels and use that for power generation. That eliminates the need to buy any gas, but these tend to be more expensive up front, so it’s a tradeoff. They also have limited battery capacity, so they need to be exposed to the sun often to charge up and generate power. If you often use your RV to go to places that are cloudy or you use your generator a lot during the night, then the gas generator might be better even though it has fuel costs.


The last consideration is the value that you get for your money. This is critical, because generators can be quite expensive, costing several hundred and into the thousand-dollar range. Efficiency, durability, wattage, features- all of these play a role in the value of any generator. With this guide, you are learning about how much these different attributes tend to cost. Don’t overpay for a flashy feature unless it is something you truly need, for example. It is a good idea to keep a tight budget and not spend over that limit even if you see a great choice. That keeps your spending under control and removes the “grass is greener” temptation that would otherwise entice you.

Full Detailed Review Of Best Electronic Ear Muffs for Shooting

1. Champion Power Equipment 75537i 3100 Watt RV Ready Portable Inverter Generator

It is rated for 3100 watts, and it can maintain that level of output for up to 8 hours before needing more gas. Also has a 120V 30A RV, two 120V 20A household and 12V DC outlets, plus wireless start capability. It has a 3-year warranty.

Compared to other generators, the 75535i provides more features and extras at a higher price. It is about average in terms of noise and gas consumption. The wireless start is occasionally useful, but not a key feature. It is a little bulky but has a convenient handle and wheels.

The 75535i is recommended for someone who has more money to spend and is willing to pay for wireless start, the port configuration, and the convenience. It is towards the upper end of the market and does not provide as much value as less expensive options, but it is well-built and should last at least as long as its warranty. The unit is small and compact considering its wattage.

  • Good feature set
  • Long warranty
  • Easy to use
  • High price compared to competing generators

2. Champion Power Equipment 75531i 3100 Watt RV Ready Portable Inverter Generator

The 75531i is very similar to the previous entry, the 75535i. The biggest difference is that this model does not have the wireless start feature and costs a few hundred dollars less. It also has a slightly different configuration of ports, but the count and type of ports is the same, as is the wattage.

The 75531i has all the same performance upsides as the other model, including the moderate sound and the portability. The lack of wireless start might affect some uses of the generator, but in general this will not materially change the way you use it. Usually, you need to keep the generator fairly close anyway because of the wires and cords that you plug into it.

The advantage of the 75531i is that you get most of the upside of the 75535i at a reduced price. As long as wireless start is not a core feature for you, then this is a better option that delivers better value. Consider this if the 75535i seemed too expensive, but you liked its outlets and other characteristics.

  • Better value than its cousin with most of the same features
  • Still priced high in comparison to some other generators

3. DuroStar DS4000S, 3300 Running Watts/4000 Starting Watts, Portable Generator

The DS4000S is considerably cheaper than the Champion models at a slightly higher wattage. It is built tough with a steel frame and has an outlet set of two 120 Volt, 20 Amp, 60 Hz-NEMA 5-20R outlets, one 120 Volt, 30 Amp, and one 60 Hz-NEMA L5-30 outlet.

This is a no-frills option that delivers power with little additional features at low cost. The DS4000S does not come with wheels or a handle, although there is a wheel kit sold separately, and has limited display and convenience features. It does its one job rather well and the steel frame protects it from most sources of damage.

The ones who will benefit most from the DS4000S are those who just want an inexpensive generator with good wattage and nothing else. The lack of wheels makes it hard to move around without the wheel package, but it is very durable and is sure to last for years. At this price, it is hard to find better value as long as you do not need any extra features, and it is fairly efficient on fuel as well.

  • Excellent value
  • Quite durable
  • Not very portable
  • Lacks any extra features

4. WEN 56475 4750 Watts, Gas Powered Portable Electric Start Generator

The Wen is a step up from the DS4000S. It costs around a hundred dollars more but has a significant increase in power, a set of wheels and a handle, extra safety and environmental features, and digital monitors for oil levels and other metrics.

The handle and wheels on the Wen are crucial, because the unit is about 100 pounds and has a steel frame that makes it a little more bulky. The biggest performance concern is having a pull start rather than a button. Other than that, it gets about 11 hours on a tank of gas at a high wattage level and has enough safety and environmental standards to be sold in California, which is not common.

The Wen is the perfect upgrade if you are thinking about wanting more power or features than the DS4000S and are willing to spend a little more. It’s tough, efficient, and high-wattage right at the sweet spot for the market in terms of value. The biggest issue is the pull start and the mechanism works well, not needing too much strength to operate.

  • Great value
  • Durable
  • Portable
  • Safe and low-emission
  • Pull start rather than a button

5. Briggs Stratton 30651 P2200 PowerSmart Series Portable Inverter Generator

The Briggs and Stratton P2200 is the smallest generator on this list. It only outputs 2200 watts and weighs 50 pounds, about half of most of these other options. It is meant for small, one-person trips or as a portable choice for times when space is cramped.

The P2200 is fairly advanced. It has a smooth form factor and a parallel port to allow you to hook up several of them at a time for more watts. Also comes with a USB port directly for smartphones and laptops. It also runs quiet.

The P2200 is a great small generator in all areas except price. It does have advanced features but the high cost and low power output make the value proposition tough. The parallel port is not that useful because it is more cost efficient to just buy a bigger generator. It’s best for those who have no use for more power and who are camping alone or need a very compact unit. It might also make a good small backup generator to a larger main one.

  • Quiet and small
  • Good feature selection
  • Expensive for the wattage level

6. Champion Power Equipment 76533 3800 Watt Ready Portable Generator

Champion’s 76533 is a different take on the RV generator because it can use propane as well as gas. It has a decently high wattage and electric start, with a 20lb propane tank capacity that gives it 10.5 hours of running as an alternative to a gas tank that delivers 9 hours of power.

As with other Champion models, the 76533 is on the upper end of the market as far as features go. The electric start is especially nice, and the wheels are well-built. The unit is durable and easy to use. It comes with a standard outlet selection and does not include USB.

If you are interested in using propane instead of gas, the 76533 is your best option. It has just as good wattage and efficiency as other generators with both gas and propane. If propane is cheaper for you, then this might be a good deal. Do note that the generator is more expensive than most non-Champion models on this list, so do some careful cost/benefit analysis to make sure it is worth it.

  • Good feature set
  • Propane compatibility
  • Pricey
  • Handle could be placed better on the unit

7. Coleman CG3500i 3500W Inverter Generator

The Coleman CG3500i occupies an odd place in the generator market. It is more expensive than average and has a limited outlet selection with just 2 120V and a 12V DC outlet. But it is very easy to use, small, and compact. Its best role is to power one or two devices that have high power draws.

The Coleman is a little noisier than other generators of the same wattage, but it has a more compact shape that makes it easier to pack. The usage is very simple and it is easy to fill it with the necessary gas and oil.

The Coleman is recommended for people who want to bring along about 3000 or 3500 watts of power draw in a few devices or appliances. It doesn’t last long due to a small gas tank, but it will automatically stop if it gets low on oil. This generator weighs about 70 pounds and has a hand handle, not wheels, but it should be possible for one person to carry it and place it where it is needed.

  • Compact
  • Expensive
  • A bit noisy
  • Not enough outlets

8. Champion Power Equipment 100302 3500W Ready Portable Generator

Champion makes yet another appearance on this list with the 100302. This is a new generator that uses digital technology to get 3500 watts at a lower noise levels than the competition. It uses a pull start and has the usual Champion array of outlets- one 120V 30A RV, two 120V 20A household, and two 12V DC outlets.

The 100302 lives up to the bill with a relatively low operating speed. It lacks the extra features that some other Champion models have, like wheels and electric start, but the price is also lower. It is very efficient with a 17-hour runtime on one tank of gas, which is excellent. Also weighs less than generators of the same wattage but without the digital design elements.

While the low noise levels are nice, it’s the fuel efficiency that really stands out for this model. The digital enhancements that Champion has added have really boosted how much you get out of one tank of gas. That gives it great value even though it doesn’t add on too many extra features the way other Champion models do.

  • Great fuel efficiency
  • Low noise
  • Not many extra features
  • No portability tools

9. Champion Power Equipment 46596 3500 Watt RV Ready Portable Generator

The 46596 from Champion is a mostly standard 3500 watt generator whose biggest advantage is its Cold Start feature. This allows it to start up more easily in cold weather conditions. As with all Champion models, it is very reliable and durable, and it also comes with an built-in surge protector.

The 46596 delivers consistently good performance. It gets 11 hours of use on a tank of gas and doesn’t require much oil to run. The dependability means you should expect this generator to work flawlessly for at least 3 years under normal use conditions. For more portability, you can buy a wheel and handle kit that makes it easier to transport.

This unit is recommended to anyone who might be using the generator in cold weather. For example, winter trips and camping where you need a generator to run heaters, furnaces, or other appliances would make good use of it. It has the standard Champion outlets and surge protection so that your connected devices are safe from power fluctuations. The warranty lasts 3 years and there is free lifetime technical support for all owners.

  • All-weather usage
  • Good efficiency
  • Wheels are sold separately

10. Westinghouse WGen3600 Portable Generator – 3600 Rated Watts & 4650 Peak Watts

The WGen3600 is a CARB-compliant generator that is reliable, efficient, and compatible with electronic devices. It gets about 12 hours on a full tank of gas, weighs slightly over 100 pounds, and comes with oil and and oil funnel.

The WGen3600 is durable and reliable. It doesn’t have any bells and whistles, but it does manage quite good efficiency and high wattage for its price. It is also one of the few generators that complies with CARB and therefore can be sold in California.

The WGen3600 is recommended to anyone who goes camping and has enough power draw to need 3600 watts. The good efficiency and durability makes this a solid, dependable unit that can support a lot of appliances.

  • CARB compliance
  • Dependable
  • Good value
  • No special features
