INIU 45W Portable Charger review – Complete Review 2026
The INIU 45W Portable Charger review starts with the fact that this model is positioned as one of the most compact power banks delivering high-speed charging for modern smartphones and tablets.
Offering Power Delivery (PD) and Quick Charge (QC) support, it claims to charge an iPhone 16 to 70% in under 30 minutes and can power up to three devices at once via USB-C and USB-A ports.
This product’s standout features include a built-in USB-C cable, robust 20,000mAh capacity using TinyCell battery technology, and a digital battery display for real-time monitoring.
Its ultra-compact design fits easily into any bag or pocket, appealing to users who need backup power on the go.
According to INIU, all models are engineered for safe charging and long-lasting battery cycles. The 3-year INIU Care warranty further boosts peace of mind for buyers. Overall, it aims to address key concerns for travelers: portability, device compatibility, and all-in-one convenience.
Key Features of the INIU 45W Portable Charger review
- Built-in USB-C cable power bank: Always ready to charge, even if you forget your cord—simply grab and go. The attached cable streamlines device charging for both Android and Apple users.
- 3 device simultaneous charging: Equipped with USB-C (in & out) and USB-A ports, this compact travel power bank supports three devices at a time, making it ideal for group trips or mixed-device households.
- High-density battery pack: TinyCell battery technology packs 20,000mAh into a slim, lightweight shell. Perfect for a phone and tablet power bank that won’t weigh down your bag.
- Safe charging technology: Multi-layered protection ensures safe and stable charging for all your electronics, preventing overheating and overcharging risks.
Real-World Performance Testing
During hands-on trials, the INIU 45W Portable Charger review proved its strengths as a quick recharge portable charger. Independent lab testing confirmed that the device can deliver up to 45W output, but this peak is sustained for only about 30 seconds before dropping to lower rates for most of the charge cycle (YouTube review).
The INIU model’s 20,000mAh capacity allowed for 3.8 full recharges of an iPhone 15 and provided around 2.6 charges to a Samsung S25 Ultra. USB-C PD and USB-A QC ports proved compatible with a wide range of devices. Charging three devices at once did slightly increase how warm the unit became.
This is typical for high-density battery pack options but worth noting for frequent multi-device users.
Total recharge time using a 27W USB-C PD charger averaged just under 3.5 hours. The built-in cable was especially useful during travel, as it removed the need to pack extras. Efficiency testing measured around 62-65%—a bit below industry leaders, but in line with most midrange compact travel power banks.
Some users pointed out that while this tool is excellent for phones and tablets, it is not suitable for powering laptops continuously or for charging large camera batteries. For more options and power station guides, see our best portable power stations roundup.
How It Compares to Alternatives
When compared to models like the Anker 737 Power Bank and the Baseus Blade 100W, this product holds its own in portability and warranty, though the latter two offer slightly higher efficiency and faster total recharge. All include fast-charging support and backlit displays.
Pricing for the INIU tends to be lower than the closest 45W output competitors. The 3-year warranty outshines typical 18-month coverage from other brands. If you need a quick recharge portable charger primarily for smartphones and don’t want added bulk, the INIU offers great value.

Who Should Buy This Product?
This tool is a perfect fit for frequent travelers who rely on phones and tablets throughout the day and value having a lightweight, all-in-one power solution.
Digital nomads and content creators whose work depends on keeping multiple devices topped up on the move will also appreciate its compact form and multi-device support.
Busy parents on family outings or commuters who forget their USB-C cables can benefit from the attached charging lead and multiple outputs. However, users needing a high-power laptop battery backup—or those wanting to power small appliances—should consider a full-size portable station instead.
