Best power banks 2023: Charge your devices on the go

The best power banks are an essential accessory for astronomers on the go and astrophotographers on multiple-day shoots.

Nowadays, the best power banks are an essential skywatching accessory for anyone, especially astrophotographers.

Out in the field, astrophotographers and skywatchers have an arsenal of kit, from headlamps, lens heaters, telescope Mounts and star trackers — not forgetting their smartphones, which are often used as star trackers or remote shutters. And as hikes and shoots can span several days, it’s quite common to run out of juice on at least one of these devices.

In order to avoid cutting your session short, a power bank is a great investment. Not all of them are created equal, so we’ve tested and reviewed a range of products with different features and price points to suit every budget.

If you’re new to the game and are wondering what to look for in the best power banks, we’ve summarized the most important things to consider at the end of this article. However, to get you started, you should look out for a device with a reliable power indicator, waterproof resistance, good portability, and an even better capacity. Some of the more premium models also function as a torch and handwarmer, which is a nice added bonus but by no means essential.

Without further ado, here is our round-up of the best power banks for skywatchers and astrophotographers. If you’re looking for more astronomy gear for your nighttime shoots, check out our guides to the best headlamps for astrophotography and the best star trackers for astrophotography.

Best power banks deal June 2023

Scosche MagicMount Power Bank: was 39.99. now 4.99 at BH Photo

Save 87%. While we haven’t tested this Power Bank ourselves, 4.99 for this 4000 mAh is too good not to share. It’s clearly designed for keeping your phone charged up, rather than any astronomy-specific gear, but as you’ll likely be using a stargazing app, this low-priced, low-profile power bank will give you a little extra peace of mind. Be quick — there’s limited availability at this price.

Zendure SuperTank Pro 100W

Best for capacity: Massive capacity power bank encased in an aluminum shell with an informative OLED screen to boot

Specifications

Output ports: USB-C1 / C2: 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A, 20V/5A, 100W Max; USB-C3 / C4: 5V/3A, 9V/2A, 12V/1.5A, 20W Max

Reasons to avoid

Zendure is one of the fastest-growing EnergyTech start-ups with a mission to make energy available and accessible.

The vast capacity Zendure SuperTank Pro 100W power bank is about as big as you can legally carry in your hand luggage on a flight. It is encased in anodized aluminum with ABS plastic which gives it a rugged but premium feel, as we discussed in our hands-on Zendure SuperTank Pro 100W review.

The Zendure SuperTank Pro 100W can charge exceptionally fast, taking only 105 minutes in lab conditions. This makes it an ideal choice if you’re looking for a quick solution before embarking on a spontaneous night of stargazing. With a total output of 138W, you can power four devices simultaneously, including your smartphone, headtorch, star tracker, and lens warmer. Amazing.

The OLED screen gives you real-time information about your power usage and remaining charge, meaning you can plan and adapt your setup accordingly.

One downside of this power bank is the lack of a USB-A port. Even though USB-C is becoming more prevalent, many devices still require USB-A charging. Fortunately, Zendure includes a USB-A adapter that can be conveniently stored in the sleek storage case.

Although the initial cost may seem significant, the firmware updates that are promised should ensure that the power bank remains useful and up-to-date in the long run.

The SuperTank Pro 100W has a two-year limited warranty for added peace of mind.

Update March 2023 — unfortunately, the Zendure SuperTank Pro has recently been discontinued; so if you’re interested in getting one, grab one quick before they sell out.

Reasons to avoid

BioLite has three versions of the ‘Charge’ power bank. Here we’ll look at the Charge 80 as it is the most powerful with the largest charge capacity.

BioLite is best known for creating affordable and durable products for life outside and off-grid — so it’s no surprise the BioLite Charge 80 PD fits this bill. over, we’re fully on board with BioLite’s mission to provide 20 million people with clean energy and avoid 3 million tons of CO2 emissions by 2025. By purchasing a BioLite power bank, you are, in part, helping with this mission.

It is rugged and simple to use, and in our BioLite Charge PD review, we thought the capacity-to-size ratio was spot on. It has enough capacity to charge multiple devices, multiple times, over a couple of days. It can charge the BioLite HeadLamp 425 (which features on our best headlamps for astrophotography list) approximately 16 times. It is made with a rubberized finish, and the ports are housed in a durable orange plastic casing.

One of the standout features is the Quick Charge 3.0 Protocol which is needed to activate fast charging modes for compatible devices. It has an LED indicator with four bars that let you know how full the charge is (25%, 50%, 75% or 100%). We don’t think an LCD screen showing exact numbers is strictly necessary, so the LED indicator is more than enough.

The Charge PD ships with a USB-A to USB-C cable, but you’ll have to supply your own USB-C to USB-C cable or something with multiple ends to be more of a universal fit.

It can operate in temperatures between.20C to 40C, so unless you travel to the most hostile conditions, there shouldn’t be any issues, however, you’ll need to store it somewhere dry.

Reasons to avoid

Designed with the astronomer in mind, the Explore Scientific USB Power Bank with Red LED Flashlight will ensure you have enough power to see your electronic devices through the night. The integrated LED with red cover will ensure you can see through the night too. It won’t light up vast areas like some of the best headlamps for stargazing but it will allow you to read star charts or locate knobs and buttons to tweak your astro setup while keeping your valuable night vision intact.

This device is by no means as ‘sleek’ as some of our other picks. It’s covered in a thick layer of rubber armor that keeps out dirt and moisture while shielding the electronics from minor impacts. It can operate in temperatures from.4 to 140F (-20 to 60C), so there’s no need to worry about protecting it from extreme temperatures.

The flashlight has a tactile toggle switch that you can use to turn it on and off. It also has a two-point attachment point so you can hang it from a convenient place, like your tripod frame. The five LED indicators show the amount of power it has left so you don’t get caught out unexpectedly.

Reasons to avoid

The Anker PowerCore 26800 is one of the more cumbersome power banks in this guide at 7 inches long and 3 inches wide. That said, we are big fans of Anker, and they are one of America’s Leading USB Charging Brands. We can happily vouch for the reliability and performance of their products, so if you’re not too concerned about having the smallest or lightest power bank, don’t let the larger size stop you.

It doesn’t offer much in the way of features — there is no flashlight or handwarmer, but it’s an extremely high-capacity power bank that can charge three devices at once. It charges from empty to full in just over four hours with the included Qualcomm Quick Charge wall charger, and it has intelligent PowerIQ technology which identifies the connected devices and delivers the optimum high-speed charge to all devices. Impressive.

It has ten tiny LEDs that indicate its level of charge. Before March 2022, the device shipped without a wall charger or cables, so we are pleased to see that a USB-C to USB-C cable and a wall charger are now included as standard, as is a no-fuss 18-month warranty.

Reasons to avoid

The Otterbox 15,000mAh (also available as 10,000mAh) is a reliable outdoor companion. It weighs 450g, which is somewhat heavy for its able size, but that is mostly due to its dense, protective rubber shell. It’s waterproof and drop-proof, giving the clumsiest or most accident-prone skywatchers peace of mind. The IP54 rating means it is totally protected from dust ingress and allows for some water ingress. No need to worry about the elements.

A basic LED indicator shows when the power bank is charging and when it is fully charged. It ships with a 150mm long USB-A to USB-C cable and delivers up to 18W Fast Charge. There’s also an easy alignment QI wireless indicator pad for wireless charge-compatible devices.

It comes in three colors; Twilight Black, New Blossom Pink and White Sands. The latter two make them easier to see when amongst predominantly black photography gear, or if you’re out on an astrophotography shoot in the dark.

Reasons to avoid

This 47 lb power station is a serious piece of equipment with a luggage-inspired design and telescopic and fixed handle mounted on industrial-grade wheels. It has 2096Wh Capacity with 2,000W Output that can be boosted to power up devices that typically need 3000W using the AmpUp feature.

While it’s obvious that you can’t just throw it in your backpack and hike to a dark sky area, it makes the perfect travel companion for extended off-grid sky-watching and camping trips.

This monster can even provide an electric car with enough juice to travel five miles, so you won’t have any trouble charging your devices for several days, including laptops, video equipment, drones, mini-fridges, and heaters.

The body is reinforced with a shock-resistant outer shell and it has a reinforced interior. Its optimum operating temperature is between 59°F to 95 °F (15°C to 35°C) but it will still work — but drain quicker — from.4°F to 14°F (-20°C to 40°C). It won’t accept a charge below freezing and, unsurprisingly, you can’t get it wet.

When not used in astronomy and astrophotography, this can be an emergency backup power source in your home. Like the rucksack-friendly SuperTank Pro 100W, this product comes with a Zendure two-year limited warranty.

Reasons to avoid

Another model from Celestron — first and foremost, it’s a night vision-preserving red flashlight. However, as with the FireCel MEGA 6, it also operates as a hand warmer and low-capacity power bank.

Despite having a relatively small capacity compared to other models in this list, it has enough power to keep your phone and other small devices charged for a night of stargazing. The hand warmer function provides up to four hours of continuous heat and can be used with the torch simultaneously.

The internal battery charges within two hours, so it’s ideal for any of those last-minute adventures. There is also a white LED version of this model, so make sure you choose the Astro version for the red light capability.

Reasons to avoid

As we discussed in our best headlamps buying guide, using a red light as opposed to a white one is essential for maintaining your night vision. While we provide a number of hand-free lighting options in that guide, the fact that this small red LED torch also functions as a 5000mAh power bank makes it a fantastic gift for someone new to astronomy or astrophotography and a useful bit of kit to keep in your bag.

It ships with silicone mount straps to attach the device to somewhere useful, like your tripod leg, and it also comes with a wrist strap. It comes with a minimum of 500x charge cycles and has overcharge protection for maximum longevity.

This is a product for a beginner or someone who doesn’t need the best of the best kit. It does what it’s supposed to do but might have a limited lifespan the more you develop your skywatching prowess.

Best power banks in 2023: What to look for

With the sheer amount of power banks available out there, making a purchasing decision can be overwhelming. We’ve summarized our advice to help you find the best device for you here.

The first thing you’ll need to consider is your budget. The price of power banks can vary widely, with some budget models costing a few dollars and some more premium ones that will set you back over a hundred bucks. Luckily, though, you don’t need to spend loads of money to find a reliable piece of kit. We’ve included devices for every budget in our guide above.

Another important factor when choosing a power bank is its capacity. The capacity of batteries is indicated as XXXX mAh (milliampere/hour). The higher the number, the bigger the capacity — the more power you can draw from it. We’ve included the capacity of each power bank in this guide so you can easily refer to this measurement.

Usually, power banks with a higher mAh are bigger and bulkier devices. So if you’re often on the go and are looking to travel light, it’s important to find a good balance dependent on your needs. There are really compact models available to purchase, including some you can attach to your keyring, which we’ve included in the guide.

Some of the more premium power banks will come with extra features such as a torch or a hand warmer. While these aren’t essential to the smooth running of your night time escapades, they may come in handy and can be worth splashing out if you have the budget.

NB — If you’re going to be traveling on a plane with your power bank and plan to have it in your hand luggage, it must not exceed the 100Wh (27, 000mAh) limit set by the Federal Aviation Administration.

All of the power banks listed here have been selected as being good value-for-money with features that are especially helpful to astronomers and astrophotographers above anything else. We will review and update this guide often and keep an eye out for discounts and deals to help you save money.

QuadraPro Solar Charger Power Bank

The day is done, you have been hiking all day, and now you are back at camp sitting around the campfire warming up dinner. You pull out your iPhone to check your Instagram and accounts, and you see the dreaded RED BATTERY! No, not now, I still have that awesome selfie that HAS to make it online TONIGHT or no one will believe I made it to the top! you scream at the top of your lungs.

It’s a scenario that plays out hundreds of times a day in the lives of the hikers, bikers, kayakers, and campers. But what now? Oh, hell yeah, you just remembered that you packed the QuadraPro that you got from Adventure Frog last week. whoo-hoo!

26800mah, 3-port, power, bank, charger

The QuadraPro is a 5.5-watt Solar Charger attached to a 6,500mAh Power Bank that will output 2-amps per port. Simply put, it’s a portal power supply with its own built-in charger. As long as you have some sunlight, the solar panels will recharge or top-off the power bank. Just plug in your iPhone, and on the next day’s hike, hook it to your backpack and let it recharge while you are cruising the trails.

The Numbers

I ran some tests to see what exactly was going on and how does QuadraPro actually perform. What I really need to know is how many amps can a power bank output and for how long. Below is a simple table of different devices you might bring with you. The first set of numbers is the amps drawn when plugged into a wall charger, and the second is when plugged into the QuadraPro.

Different Devices

  • GoPro Hero5 Black 1.22A 1.10A
  • GoPro Battery Charger (2) 1.57A 1.36A
  • iPhone 10 1.04A 1.06A
  • iPad Air 2.01A 1.83A
  • Nikon D500 Battery Charger 2.2A 1.89A

A typical battery is about 80% efficient, so doing the math the 6,500mAh QuadraPro should be able to provide 1A over roughly 5 hours. But as the amount stored goes down, the battery has to work harder (that’s why a flashlight goes dim as the battery voltage drops when used too long) and that cuts down on your time. During my testing, I was consistently getting a little more than 4 hours of usable time. Not too shabby for a portable device like the QuadraPro.

Note: Some devices like all Apple products have built-in monitors that will adjust the amount of amps drawn to maintain the needed level of voltage in order not to damage the device. This can cut the total time available for charging. Also, a device that is almost dead will draw far more amps than one that is at 75%.

Final Thoughts

The QuadraPro is a great little power source that balances available power with weight and size making this a great tool to keep your iPhone charged on multi-day trips provided that you keep the solar panels in direct sunlight every chance you get.
