Ronin Cyan R-4075 10000mAh Power Bank

Ronin R-4075 10000mAh Power Bank: small, quick and flight-friendly

Most people don’t need a brick of a power bank. They need something light enough to carry every day that can bring a phone back from 10% before the evening plans start. That’s the job the Ronin R-4075 does well. It holds 10000mAh (3.85V, 38Wh), charges at up to 22.5W and has a clear digital display on the front, all in a textured Cyan body that doesn’t slip out of your hand.

If you’re comparing options, the R-4075 sits between Ronin’s budget 10000mAh models and the bigger Ronin AQUA R-4070 20000mAh. Not sure which size you need? Our guide on 10000mAh vs 20000mAh power banks explains it in a couple of minutes.

Key features of the Ronin R-4075

• 22.5W fast charging: up to 22.5W from every port, with PD on the Type-C ports, so supported phones charge noticeably quicker than with an old 10W bank.
• Three ports: 2 x Type-C plus 1 x USB-A. Charge your phone, earbuds and smartwatch at the same time.
• 20W fast refill: both Type-C ports work as inputs, so you can recharge the power bank with the same cable and charger you already use for your phone.
• Digital % display: shows the exact battery level, so you know when it’s time to plug it in.
• Flight-friendly 38Wh: well under the 100Wh cabin-luggage limit used by airlines.
• Multi-protection safety: built-in protection against overcharging, short circuits, over-current and overheating.
• Type-C cable included: a short Type-C charging cable clips to the corner of the power bank, so you can top up your phone even when you forget your own cable.
• Grippy Cyan finish: textured back, ribbed sides and a bright orange power button that is easy to find.

How many times can the R-4075 charge my phone?

A 10000mAh power bank never puts the full 10000mAh into your phone, because some energy is lost converting the battery voltage. Ronin rates the usable output of the R-4075 at about 5800mAh. In everyday use that means roughly one full charge for a phone with a 5000mAh battery (most Samsung, Xiaomi, Infinix and Tecno phones), and around one and a half to almost two charges for iPhones with smaller batteries. For a single long day away from a socket, that’s usually plenty.

Recharging the power bank

Plug a 20W (or higher) PD wall charger into either Type-C port and the R-4075 refills in about 4.5 hours. On an old 2A charger it takes 8 to 12 hours, so overnight is fine too. If you don’t have a fast charger yet, have a look at our chargers.
