If you have a newer Android phone, or the latest iPhone 15 models, you'll want a power bank with faster charging speeds to get your battery full faster. Charging speed is measured in wattage, and the iPhone 15 can charge just a bit faster than 15W, while the Galaxy S23 Ultra can charge up to 45W.
The Anker Prime series of Power Banks, including the Anker Prime 27,650mAh Power Bank (250W) and the Anker Prime 20,000mAh Power Bank (200W), are for people who truly love to geek out on power banks. If you came looking for the absolute best power bank you can buy, this is the best we've tried. As you charge your power bank, you deposit electrical energy into the battery. Later, when you plug your device into the power bank, withdraw that same energy and use it to charge your device. Basically, you’re trying to balance four factors: size, speed, capacity and price. The rules are simple enough: the less you spend, the lower the capacity and the slower the power bank will charge.
The best power banks you can buy in 2023
In this review, we have thoroughly examined the various aspects of the affordable 20000mAh power bank to meet the specific needs of potential buyers like you. A portable power bank consists of a special battery encased in a particular case with a unique circuit to control power flow. Using them, you can store electrical energy (deposit it in a bank) and then use it to charge a mobile device later (withdraw it from the bank).
Pass through charging is a feature we rarely see in powerbanks. Pass-through charging simply means charging one or more devices in the powerbank while the powerbank is being charged itself. The iMuto 20000mAh powerbank supports pass-through charging and has two charging ports. Which means you can charge two devices plus the power bank at the same time. This can save you a lot of time as you now don’t have to take turns charging. A very handy feature. However, I’d recommend you to not use pass-through charging too often though, as it can shorten the battery life of both your device and the powerbank. The iMuto takes a little bit of a different path when it comes to its design because most high capacity portable chargers take the long length kind of form factor but the iMuto is more short and stubby. We expect this competition will heat up next year as more power bank makers catch up and make faster charging batteries. Until then, Anker is the dominant brand, and if you want the best it's an easy choice. How many times can my power bank charge my phone?
Power Capacity
Additional USB-C and USB-A ports also mean you can charge other devices, like an iPad or even a gaming laptop, while you're on the move, making it a versatile option for your travels. Charging 2 tablets at the same time may lower their charging speed to 1.5A each with the max output being 3.1A though. Input Charging: 5V/2.0A 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.
Great Deal
