Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB. The number and type of devices you need to charge as well as the length of your sessions will affect how big a power bank you need. You need a lot of power: Thankfully, the battery on the Tylt Bottle 2 isn't so big it adds too much weight, but that also means it isn't powerful enough for multiple charges. It will charge a typical modern smartphone from 0% to 100% between 22 and 26 times. This is more than enough for a week-long session with a tablet, phone, camera, and laptop… Overall, this is a great power bank for the holiday angler or someone that heads out for long sessions and needs plenty of power and outlets. However, if you’re looking for even more power the next power station may be more up your street…

To test charging times and claims, we charged a Samsung Galaxy S23 Ultra and an Apple iPhone 15 to determine how many charges each battery offers these devices. We chose a common smaller battery phone as well as our best phone overall for this purpose. You're trying to keep it simple: The Baseus Airpow doesn't have any built in wires or wireless charging, so you'll need to carry extras when it's time to power up. In fact, our testing confirms what battery makers usually claim. A battery maker will claim between 60% and 70% efficiency, so that 10,000mAh battery will only give your phone around 6,000mAh of extra battery charge, at the least. In practice we find around 65% efficiency, though occasionally we can do even better. The addition of a solar panel means you can stay connected on the bank in a truly renewable fashion. Next, you should ask yourself how many outputs you need on your power bank. How many electric devices do you bring on a typical session and how many will you need to charge at the same time?Now, these stats are actually quite comparable to the Fox Halo 96k power bank. Honestly, if you just need something for charging simple appliances such as phones, tablets, laptops, and batteries I’d opt for the Fox Halo power bank. However, the Anker Power Station comes into its own because of its range of outlets. Now on to the next RidgeMonkey product on the list. The 77850mAh C-Smart Vault is a more powerful version of the Vault above. This one is for the angler that perhaps takes longer sessions or brings more power-hungry electronics to the bank. This is the ultimate power station for the long-session holiday angler. It will charge a smartphone from 0% to 100% a staggering 52 times or more. It will also power a laptop for 30 hours, a mini-fridge for 10 hours, and charge a high-end camera over 25 times. The Ridgemonkey Vault has a few differant connections from superfast USB-C Power Delivery, dual 3A USB-A ports and a 12V DC output, this means you can charge almost everything, from Laptops to power pumps and bait boats, this thing really gives you altimute power on the bank.

There are also cool additional features to consider. Our favorite power bank has a built in charging plug so it can go right into a wall outlet. Some power banks have data about your charging devices. Some are just super small and cute. Which power bank is the best quality? Our favorite power bank has a 10,000mAh battery, and the Samsung Galaxy S23 Ultra has a 5,000mAh battery, so the math should be simple, right? It charges twice. Except that's not how it works. Power banks are not 100% efficient, and even though you start with plenty of power, a lot of it is lost in the charging process. For me, the maximum I charge at any one time is two items. I rarely like to charge my laptop and phone simultaneously but it does come in handy sometimes if I’m watching a film on the laptop and need to charge the phone as well. It has dual USB-A outputs, a USB-C fast-charge output, and two 12v cigarette lighter outputs. It also has a large high-power bivvy light incorporated in its design. Four LED lights indicate battery life remaining (all four lights illuminated = 100% charge, 1 light = 25% charge left)You have a watch that isn't from Apple: The Otterbox 2-in-1 Power Bank only attaches magnetically to the Apple Watch. Other smartwatches, like the Pixel Watch, won't work with this one, not at all. If you want a power bank that’s guaranteed to last for the duration of your session no matter how many electronic items you bring, then this is a great choice. It’s not super bulky but it has enough capacity for most anglers, even if they’re dabbling in a bit of film and photography while they’re out on the bank. You can also charge the Anker Prime using both USB-C ports at the same time, for a combined recharging rate up to 170W. That means you can completely refill this whopping 27K mAh battery in under 40 minutes. I thankfully had an Anker 737 GaN Prime charger that was up to the task, and it's fun to see the percentage climb.

That app is essential because there's a Find My feature built into the battery. It doesn't work like an AirTag over UWB, it's only Bluetooth, but it's useful if you misplace your battery in your office (or you have multiple batteries, like I do). The next question is how you want to charge your device. You can find a power bank that charges your phone (or even your Apple Watch) wirelessly. These will usually charge slower, but they can be very convenient if you want to leave wires at home. The most important thing to do is to match the battery’s output to your phone’s input. For example, if you have an iPhone, be sure the battery has its own Lightning connector or supports USB-A-to-Lightning or USB-C-to-Lightning cables. the Atom 78 from Powapacs offers a high 78,000 mAh 312Wh capacity from a 18650 lithium battery and can be charged in three ways; via mains electric, using a 12-24V car adapter and a revolutionary new solar panel (sold separately).Speaking of that wall plug, it's the most useful feature ever on a power bank. Some power banks come with a built in USB-C cord, but this Anker comes with a two-prong power outlet plug. That makes it a wall charger as well as a power bank, and the utility can't be understated. The second thing to consider is what type of outputs you need on your power bank. This goes for the type of outlet as well as the voltage outputs. We wish there wasn't such an easy answer to this question, because competition is better for everybody, but Anker is making the best power banks right now by far. It offers the best power-to-weight ratio, the fastest charging, and the most useful features. What this is, is a simple power bank with a decent capacity that pretty much anyone can afford. It has two USB-A ports, one USB-C port, and supports fast charging. It can be fully charged in as little as 3.5 hours and will last the average angler a couple of nights on the bank. For the more serious campaign angler, a power bank of 70,000 to 100,000mAh may be a smarter option. This kind of size will keep you going for one to two weeks depending on what you’re charging with it.

In terms of charging, this massive power bank can charge an iPhone 15 more than five times. It can charge a big Galaxy S23 Ultra's 5,000mAh battery three-and-a-half times. Best of all, it charges at the fastest speed available on most of your favorite phones (excluding Oppo/OnePlus's unusual SUPERVOOC battery). Yes, the Halo Bolt is powerful, compact, and easy to use, making it capable of safely jump-starting your car. Additionally, it can be used to charge your phone, tablet, or other electronic devices. The Halo Bolt also features a convenient LED floodlight. 4. Can a Halo power bank jump-start a car? Some battery makers have built Qi or MagSafe-compatible wireless charging into the surfaces of their portable batteries. Such batteries mean you can leave the cables at home.The INIU power bank is very popular amongst anglers and people who partake in outdoor activities mostly due to its lightweight, strong capacity and low price. Here are some key details about the INIU power bank. Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common. It has wireless charging capabilities as well as one USB-C outlet, two USB-A outlets, and one cigarette lighter 12v outlet. This allows you to charge everything from phone, camera, and tablet batteries while powering 12v appliances (within reason) such as a camping refrigerator. We have tested the best power banks by using them to charge a variety of devices, including Apple iPhone, Google Pixel, and Samsung Galaxy phones. We have also charged Apple iPad tablets, and small laptops including a Pixelbook Go and a Surface Laptop Go.
