Belkin 4,000 mAh Power Bank, Dual USB Portable Charger, Battery Pack for Apple iPhone, iPad, iPod, Samsung Galaxy and Universal Smartphones/Tablets - Blue

Product Information

You want a more portable option: Because of its combo nature, the Anker 733 is a bit bulky and cumbersome, but if you use it both ways, it's worth the trade-off in size to have such a useful device. What’s more, we offer a range of attractive designs and colours, with our portable charging products manufactured by top brands like Cosmopolitan and Goodmans. First, it’s important to account for the conversion losses and energy efficiency of the power bank. As mentioned earlier, these losses can vary between models and brands. Higher-quality power banks typically have better efficiency, resulting in lower energy losses during the charging process.

Power bank users with special requirements or for certain scenarios will find that 7,000–10,000 mAh is a viable alternative. And definitely get a 10,000+ mAh power bank for your tablet or laptop. To meet your different needs, Anker offers you a list of power banks of various capacities, get your own Anker power bank here. FAQ 1. What's a Good Amount of mAh for a Portable Charger? You can buy the Tylt Bottle with just a power bank attached, but our review sample from AT&T had the full wireless charging treatment. It's easy to set up a phone to charge while studying, working out, or working away from home: all places we take a water bottle and need a full phone battery. To make the most out of your 4000mAh power bank and ensure its longevity, consider implementing the following tips and practices:

The best power banks you can buy in 2023

Over 20,000 mAh power banks are typically for camping or vacation because they can charge all of your portable electronics for a day.

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. When it comes to power banks, the term mAh, short for milliampere-hour, plays a significant role. It refers to the capacity of the power bank and indicates the amount of charge it can store. The higher the mAh rating, the more charge the power bank can hold. 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? When it comes to charging devices with a 4000mAh power bank, the charging time can vary depending on several factors, including the device’s battery capacity, charging speed, and power bank efficiency. Let’s explore the typical charging times for different devices to gain a better understanding.

However, in reality, due to conversion losses and other factors, the actual charging capacity may be lower. A conservative estimate would be to assume an efficiency of around 80% for most power banks, resulting in an effective capacity of approximately 3200mAh (4000mAh x 0.8 = 3200mAh). In addition to conversion losses, the performance of a 4000mAh power bank can also be affected by the efficiency of the device being charged. Different devices have different power requirements and charging efficiencies. Some devices experience higher power loss during charging, resulting in a reduced charging capacity for the power bank. Using the Anker Prime power bank, we were also able to test the charging speed claims of other power banks, as the Anker Prime will report charging speed in wattage. Considering these conversion losses and other factors, it’s important to be aware that the actual usage and charging capacity of a 4000mAh power bank may be slightly lower than its specified capacity. However, even with these losses, a well-maintained and efficient 4000mAh power bank can still provide multiple charges for your devices.

Additionally, it’s worth noting that the number of charges provided by a power bank is not linearly proportional to the device’s battery size. The conversion losses and energy inefficiencies mentioned earlier can result in a reduction in the overall charging capacity. The Juice ECO 1 Portable Power Bank with 4,000mAh (One Full Charge) battery capacity. The ideal accessory for day to day use. Forget that bulky mains charger in your bag – grab the Juice 1 before you leave the house, knowing you have a cheeky full charge on hand incase you run low on juice.By understanding the real-world performance of a 4000mAh power bank and considering the factors that can impact its usage, you can make the most out of its capability and ensure that your devices stay charged and ready for use when you need them.
