The Venture 30 can be recharged via either solar power (panels not included) or USB – the latter takes around 3 hours. Use your power bank regularly. Run a simple charge and discharge cycle once a month to help maintain the internal battery
The brand’s Rugged and Waterproof Power Bank has a capacity of 30,000mAh, an IPX6 durability rating, and can withstand a three foot drop. It has two standard USB ports, one 18W fast-charging USB-C port, and a 45W fast-charging USB PD (power delivery) port. Its USB-C PD port can transfer enough power to charge a laptop like the MacBook Pro. Generally, power bank capacity is measured in milliamps per hour — mAh. This unit indicates how many milliamps of electric current a given power bank can deliver per hour.The “Fast Charge” moniker sets up high expectations. This power bank fully charged an iPhone 13 from dead to 100% in just over 90 minutes. While this stat is competitive for a small power bank, it’s about the same as several other top performers on this list. This Otterbox is a reasonably fast-charging product, but it’s on par with its peers on this list, not necessarily superior. Pros: Lightweight, versatile, easy to use and eco-friendly, since it uses rechargeable batteries rather than a lithium ion cell, and reduces your reliance on single-use AA batteries. The maximum power the AC50S can deliver is 300W. This is enough to power a TV, an electric cool box, a laptop and even a very low power electric camping kettle, although it would take about 20 minutes for water to boil. With the AC50S, you can power multiple items at once, but remember that the combined power of your gear cannot exceed 300W. The Hobest Solar Charger is one of the best waterproof power banks for outdoor enthusiasts because not only can it hold enough charge to charge your phone up 3 or more times, it can also be recharged using the sun. But the features don’t end there. Dual charging ports with 1A and 2.1A outputs for smartphones and tablets, LED power level display, and dual-LED torch lights with three modes. The casing is tough and sold as waterproof but no IP rating is given.
Compatibility: Ensure that the power bank is compatible with your devices. Look for multiple output ports to charge various devices simultaneously. The Sherpa charged an iPhone 13 from dead to 100% a whopping seven times using a USB-C to USB-C cord. The brand advertised eight full charges, but this figure depends on many variable factors. In any case, the Sherpa is about four times more powerful than most 10k mAh power banks in this regard. Using the wireless charging surface, the phone fully charged in about 100 minutes. The best power banks we have tried have all come from Anker, but that doesn't mean Anker is the only brand you should consider. All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home. Anker is the best, but these batteries from Baseus and Otterbox performed well. Brand Reliability: When it comes to portable power banks, it's essential to choose a trustworthy brand. Brands like Anker have a solid reputation for producing safe and high-quality products, ensuring your devices are charged efficiently and without any risks. Use the cables supplied with either your device or your power bank. Cheap, inferior cables increase resistance, which can increase battery drain and adversely affect charging speeds

There are plenty of other power bank makers around, and most of them have not caught up to the faster charging speeds available on the iPhone 15 family, let along even faster Android phones. Except for unique form factors or serious bargains, we stayed away from recommending power banks from reputable makers if they couldn't charge at 2023 speeds. Another compact and relatively lightweight power bank with an integrated solar panel that can fully recharge its 6,000mAh internal battery in 28 hours of sunlight. However, with the Supercharger solar panel attached, charge time is reduced to around 8 hours, or 6 hours if all the solar panels are in direct sunlight. The Freeloader Sixer has a 2.1A USB output as well as integrated micro-USB and lightning cables, enabling up to three devices to be charged simultaneously.
If you only need a small waterproof power bank to use in emergencies to charge your phone, then this is perfect. It stays charged for weeks at a time if you don’t use it, and it doesn’t matter if it gets covered in dust, mud, or soaked in the rain. All power inputs and outputs on the Pro are hidden beneath a rugged mini door. A small LED flashlight sits next to the USB-A and USB-C ports. Four battery indicator lights relay the key information that users need. In the end, it’s best to assess your typical needs before buying. If your phone hits the red zone by mid-afternoon and you only need enough juice to get you to the end of the workday, a 5,000mAh battery should be plenty. The most important question to consider when buying a power bank is what will you be charging? If you are charging a small smartphone and that's all, a simple power bank will suffice. If you plan on charging a laptop occasionally as well, or many devices at once, you'll want something with more power and more features. Here are more things you’ll need to consider when buying a power bank or solar charger. What is a mAh and how much do I need?
The Venture 70 also has a smart charge feature that can identify different devices. It then applies the fastest charging profile possible, without risk of overheating or overcharging. It also allows pass-through charging. That means you can safely charge devices from the power bank even when it’s plugged into the mains. We also liked the built-in 65-lumen LED torch, which has two brightness settings and three strobe modes, including SOS. To boost the capability, you can also add a separate folding solar panel with a max 10W output. It connects to the Power+ via a link box. This also has a second USB port so you can charge another device simultaneously. Setup is simpler than it sounds, and the Power+’s LED indicators tell you how much juice it has left as well as how effectively it is charging from the sun. On solar, you can get similar charge times with the max input of 800W, but you need alot of panels which can get expensive. We love that you can mix the AC charging with solar for combined charging. This is great in the UK where the sun is a temperamental beast! Output Power – Unleash The Force We like that this simple power bank is free of frivolous features. It serves its purpose perfectly and doesn’t pretend to be anything more than a reliable power bank. The easy-to-read LED display allowed us to keep accurate tabs on its battery life. Its rate of power delivery is right up there with the best banks on the market, but the bank itself is fairly low to charge. 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.
One advantage of this shift to USB-C is that power banks now support USB PD for faster charging. This means your power bank will often recharge faster when connected to a suitable fast charger, at anywhere from 20W to 60W. At those speeds, even a high-capacity charger can recharge fully in three to four hours. You only want to charge a phone: If you don't need to charge a laptop occasionally, or you only carry a phone with no accessories, the Anker 733 is more than you need. If you are looking for a highly portable power bank that doesn’t add too much bulk to your carry, the Powerness U36 waterproof power bank is for you. It sports a compact size and has a 10,500mAh battery inside that can charge your phone up to 2 times. It has a USB-C and a USB-A port for charging multiple devices simultaneously.Some power banks have an in-built LED torch which is a fantastic benefit to have in your bag, and used as a flashlight alone would last a very long time. Even a small charge display can be a big advantage, as knowing how much power you have left allows you to ration it better. Are Anker Power Banks Waterproof? Congratulations on your new power bank! To ensure you get the most out of it, here's what you should do when you first buy one:
