Choosing the Best Gear for Camping

how to choose a portable power supply correctly

Millions will be traveling over Labor Day long weekend , perhaps as a last hurrah to cap off a fun summer. While many will be camping , cottaging , or RVing with family and friends, its also nice to have the luxcries of home, such as electricity and internet. As such, emissions-free electric generators are a smart solution for campers, to power lights, laptop, CPAP machines , electric grills, and coffee machines.

So, how to choose a portable power supply correctly?

  • First,look at the casing

The plastic shell has good insulation, can avoid leakage, and can maintain toughness at low temperatures. However, the heat resistance is not good. It will become soft and melt if it is too hot. It is easy to age and shatter after a long time, it is not good for the heat dissipation performance.

The aluminum alloy shell is fireproof, waterproof and anti-drop, more durable. The aluminum alloy shell has a relatively low density, is lighter and better to carry, wear-resistant, corrosion-resistant, anti-static, and has better heat dissipation, making it more suitable for use in harsh outdoor environments. However, the cost of outdoor power supply with aluminum alloy casing is higher, the price is naturally more expensive, and the casing is broken and more difficult to repair.

  • Second, look at the battery

Lithium batteries for outdoor power supplies are generally made of ternary materials, mainly 18650 models. The advantages are light weight, small size, long life and high stability. It is the most extensive and mature material in the lithium battery industry.

Lead-acid batteries are heavy, short-lived, and polluted. They have been eliminated by many battery manufacturers. We should never buy this type of battery when choosing an outdoor power supply.

LiFePO4 battery is a new type of lithium battery, which is theoretically more stable and safer than ternary materials, but the current development is not very mature, and the quality and price are not ideal.

Therefore, the first choice for us to buy outdoor power supply is the lithium battery of ternary material, the second is lithium iron phosphate battery, and the lead-acid battery is abandoned.

  • Third, look at the capacity

The larger the capacity of the battery, the longer the working time. Some manufacturers say how many watt hours (WH), and some say how many milliamps, 1 kWh = 1000 watt hours = 1000WH. Generally, the introduction of outdoor power supply has corresponding electrical use time. As a 220V outdoor power supply, the capacity can reach 500wh-1000wh.

The larger the capacity, the heavier the natural weight will be, which is not conducive to our travel. We can choose the capacity enough for daily use. There is no need to buy a generator to go out.

  • Fourth, look at the power

The output power of the outdoor power supply can drive high-power electrical appliances. Some businesses have more routines. The target is not continuous power. The maximum power marked by the seller has no meaning for our outdoor equipment. What we need is continuous and stable output. Power, not the instantaneous maximum power, we must ask this clearly.

There are generally two types of inverters for outdoor power supplies, namely square wave and sine wave. The square wave can carry resistive appliances with full power, such as rice cookers, light bulbs, and LED lights; but the inductive appliances need to be reduced, such as chargers and fans.

  • Fifth, look at the port

A good outdoor power supply is generally equipped with a 220V wall plug interface (AC interface), preferably a 12V DC interface, which can be used for lighting, and a 5V USB interface for mobile phone charging.

Considering that the outdoor environment is relatively harsh, the output port should preferably be made of gold-plated or silver-plated material, which can be more durable and corrosion-resistant.

Which brand of outdoor power supply is good, and what are the cost-effective recommendations?

Evaluation: WANROY was established in the United States in 2020, and its products include portable power stations, lithium iron phosphate batteries, and solar panels. Its products focus on using the latest technology to enable more people to use clean energy, reduce carbon emissions, and protect the environment for human survival.This product is a backpack-type portable power supply, which is easy to carry and travel, with a capacity of 540Wh, small size, light weight, high cost performance, and can meet the needs of outdoor power consumption.

  • Jackery 500w portable power station

Evaluation: Jackery started out as a mobile phone power bank, and later transformed into an outdoor power supply, entering the market earlier. It has invested a lot in marketing, and the promotion of Jackery can be seen on many travel bloggers. The product marketing is really strong, so that self-driving travel enthusiasts will remember this brand.

However, the product power of Jackery is not particularly strong, and the product investment is not very high. Compared with other brands, there is still a certain gap in performance, which is a pity.

The inverter does not have independent research and development capabilities, and is installed by outsourcing inverter modules, resulting in a large volume and weight, the shell is still plastic, the heat dissipation is not good, and there is noise.

It is not very good for use in a slightly harsh environment. It is generally waterproof and dustproof, and its service life is not long. It can only be regarded as a consumer outdoor power supply product. It is expensive and not durable.

  • EcoFlow RIVER Pro Portable Power Station

Evaluation: It is large in size and heavy in weight. It is a little difficult to carry with one hand. It is more suitable for fixed position use, and it is not very convenient for outdoor camping.
