Capacity, Size, and Charging Speed

Battery Capacity

Edge: INIU 20000mAh 45W Portable Charger

The INIU 20000mAh 45W Portable Charger offers double the energy storage of the INIU 10000mAh 45W Portable Charger. With 20,000mAh, the larger unit provides approximately four full charges for most smartphones or two full charges for tablets. This makes it suitable for longer trips where wall outlets are scarce. The 10,000mAh model provides nearly two full charges for a smartphone. If your daily routine involves heavy device usage or multi-day travel without access to power, the higher capacity model ensures you stay connected longer. The lower capacity unit is sufficient for daily commutes or short outings.

Physical Dimensions

Edge: INIU 10000mAh 45W Portable Charger

Portability depends on how the units fit in your bag. The INIU 10000mAh 45W Portable Charger measures 5.26 inches in length, 2.7 inches in width, and 0.5 inches in height. The INIU 20000mAh 45W Portable Charger is slightly shorter at 4.5 inches long, but wider at 2.9 inches and significantly thicker at 1.1 inches. The 10,000mAh model is also lighter at 8.11 ounces, while the 20,000mAh model weighs 11.5 ounces. The smaller unit slides easily into pockets or small pursues. The larger unit is comparable to the weight of a soda can but takes up more vertical space in a bag.

Output Wattage

Edge: Tie

Both power banks deliver the same maximum output power of 45W. This allows you to fast-charge compatible devices like the iPhone 17 Pro Max, Galaxy S25 Ultra, or iPad Pro up to 60-84% in just 30 minutes. The charging speed is identical for both models when connected to a single device. This high wattage ensures you spend less time tethered to a wall and more time on the go. Whether you choose the smaller or larger capacity, you get the same rapid charging performance for phones and tablets.

Built-In Cable Design

Edge: INIU 10000mAh 45W Portable Charger

The cable design differs between the two models, affecting convenience and durability. The INIU 10000mAh 45W Portable Charger features a 0.4ft detachable braided USB-C cable. This allows you to swap the cable if it breaks, potentially extending the life of the power bank. The INIU 20000mAh 45W Portable Charger has a fixed built-in braided USB-C cable that is tested for over 10,000 bends. While the fixed cable eliminates the risk of losing a separate cord, it cannot be replaced if damaged. The detachable option offers more flexibility for long-term use.

Extra Features

Edge: INIU 20000mAh 45W Portable Charger

The INIU 20000mAh 45W Portable Charger includes a built-in flashlight, providing extra utility in emergencies or low-light situations. It also supports charging up to three devices simultaneously. The INIU 10000mAh 45W Portable Charger does not list a flashlight or multi-device simultaneous charging capability in its specifications. For users who need emergency lighting or want to charge multiple gadgets at once, the larger model offers more versatility. The smaller model focuses on core charging functions without these additional features.
