As someone who’s spent the last decade exploring the backcountry and advising others on outdoor gear, I can tell you one thing: reliable power is no longer a luxury, it’s a necessity. Whether you’re a weekend camper, a full-time van lifer, or an outdoor professional, keeping your devices charged is crucial for safety, communication, and comfort. The Anker 737 weight and capabilities have quickly made it a standout option, but the world of portable power is vast. This guide will break down everything you need to know about choosing the right power solution for your next adventure, from simple power bank five below options to robust power stations for CPAP camping.
Before diving into specific products, let’s demystify some key terms. Understanding these will save you headaches (and dead batteries) later. The first is wattage. This measures how much power a device consumes. Your phone might draw 5-15 watts, while a CPAP machine can require 60-100 watts or more. Next is mAh (milliampere-hour) or Wh (watt-hour). These measure the capacity of a power bank or station – essentially, how much energy it can store. A higher mAh/Wh means more charging cycles. Finally, consider the output ports: USB-A, USB-C, and AC outlets (battery pack with 110v outlet).
Think about what you need to power. Is it just phones and headlamps? Or do you need to run a cooler (like the Anker Power Cooler), a CPAP machine, or other higher-draw devices? Creating a power budget is essential. List all your devices, their wattage, and how long you’ll use them each day. This will help you determine the necessary capacity.
For those relying on a CPAP machine while camping, accurate power calculations are vital. CPAP machines vary significantly in their power draw. Check your machine’s specifications – it’s usually listed on the power adapter. If you’re looking for the best portable power station for CPAP, you’ll need a unit that can handle the continuous wattage and ideally has a pure sine wave inverter (more on that later). Many users find the best portable power supply for CPAP machine is one with at least 300Wh capacity for a single night, and potentially more for extended off-grid stays. Don't forget to factor in humidifier usage, which adds to the power demand.
Let's start with the basics: power banks. These are great for keeping phones, cameras, and smaller devices charged. You can find a decent power bank five below for under $20, but quality and capacity vary greatly. For a step up, consider brands like Anker, Goal Zero, and Zgear. The Zgear power bank line offers a good balance of price and performance.
Don't overlook features like pass-through charging (use power bank while charging) and multiple output ports. Some power banks, like the Anker Flex Collection Mobile Power, even offer wireless charging.
When you need to power larger devices or run appliances, a portable power station is the way to go. These are essentially large-capacity batteries with AC outlets, USB ports, and often, solar charging capabilities. The Anker 511 portable power station is a great entry-level option, while the Anker 511 powerhouse offers significantly more capacity.
Here's a quick comparison:
| Feature | Anker 511 | Goal Zero Venture 75 | Jackery Explorer 500 |
|---|---|---|---|
| Capacity | 512Wh | 75Wh | 518Wh |
| AC Outlets | 2 | 1 | 2 |
| USB Ports | 3 | 2 | 3 |
| Solar Charging | Yes | Yes | Yes |
| Weight | 12.8 lbs | 4.6 lbs | 13.8 lbs |
When choosing a power station, consider the inverter type. A pure sine wave inverter is crucial for sensitive electronics like CPAP machines and laptops. Modified sine wave inverters can sometimes cause issues.
For van lifers, a reliable power system is essential. The best portable power station for van life depends on your energy needs. If you’re running a fridge, lights, and charging devices, a 500Wh+ station is a good starting point. Many van lifers combine a power station with solar panels for continuous charging. The Goal Zero Venture 75 review often mentions its suitability for smaller van setups due to its portability and solar compatibility.
So, you’ve got your power bank or station. Now, how do you recharge it while camping? Here are your options:
Remember to check the charging time for your power bank or station. Solar charging can be slow, especially on cloudy days.
For the resourceful camper, building your own power solution is an option. An ammo can battery box is a popular choice, providing a rugged and waterproof enclosure for your battery and components. However, this requires electrical knowledge and careful planning to ensure safety. Always use appropriate fuses and wiring. You can also find pre-made battery box camping kits online.
Portable power is convenient, but safety should always be your top priority. Here are a few tips:
