Family charging chaos usually starts small: a phone plugged in here, a tablet dying there, and then suddenly every outlet is spoken for. In many households, one power bank becomes the most fought-over object in the room.
Nimble’s latest SharePower takes that familiar frustration and reframes it into a simple hardware idea. Instead of adding more ports, it changes the charger’s structure so it can physically split and serve two people at once in practice.
What is the Nimble SharePower charger?
Nimble’s SharePower is a $79.95 modular power bank with a 10,000 mAh capacity. Its 2 magnetically connected 5,000 mAh modules can be used together or separated, allowing 2 people to carry and use independent battery packs.
In Stack Mode, the joined unit provides up to 35 W of total USB-C Power Delivery output when charging 3 devices. In Share Mode, each module provides up to 20 W. The design is intended for users who want 1 power bank that can also be divided for sharing.
How split mode charging works
In Share Mode, SharePower separates into 2 independent 5,000 mAh modules, each capable of up to 20 W USB-C PD output. This allows 2 people to charge 1 device each simultaneously.
In Stack Mode, the modules reconnect magnetically to provide 10,000 mAh of total capacity and up to 35 W of combined output when charging 3 devices. The primary module has a foldaway USB-C connector, while the secondary module has an integrated lanyard-style USB-C cable. Each module also includes an additional USB-C port.
The modules can be recharged together or separately. When they are reconnected, the system balances the remaining power between them.
Why do families notice the difference?
SharePower’s split design can be useful when 2 people need to charge their devices simultaneously. Each person can carry a separate 5,000 mAh module instead of remaining near the joined power bank.
The modules can also be kept in different bags, rooms, or vehicles and later reconnected. This makes the product more flexible than a single-piece battery pack for households or travel companions who regularly share charging equipment.
The design does not eliminate every need for extra cables or chargers, but it can reduce competition for 1 shared power bank.
Charging specs and everyday performance
SharePower has a total capacity of 10,000 mAh. Nimble estimates that it can provide approximately 1.5 to 2 full phone charges, depending on the device and charging conditions.
Each 5,000 mAh module delivers up to 20 W through USB-C PD in Share Mode. In Stack Mode, the joined unit provides up to 35 W of total output when charging 3 devices.
The charger prioritizes modularity and portability rather than laptop-class output. In WIRED’s testing, 1 module charged an iPhone 16 from empty to 80% in approximately 1 hour, while the other charged a Pixel 10 Pro XL from 12% to 72% in approximately 45 minutes.
Little-known fact: The average smartphone’s battery capacity jumped to 5,291mAh by January 2026, a roughly 400mAh year-over-year increase that’s the biggest jump since 2021.
Built-in cables and display features
SharePower does not use the same cable arrangement on both modules. The primary module has a foldaway USB-C connector and an LED display that shows the exact remaining charge and charging status. The secondary module has an integrated lanyard-style USB-C cable and separate LED indicators.
Both modules also include an additional USB-C port, allowing users to connect their own cables when needed. This arrangement gives each module a built-in charging connection while retaining support for other USB-C devices.
Little-known fact: New EU ecodesign rules that took effect in late 2025 require every USB-C cable to be marked at its plugs with a power rating of either 60W or 240W.
How it compares to typical power banks and hubs
Most conventional power banks focus on increasing capacity or adding multiple output ports, but they remain single physical units, which limits how flexibly they can be shared between users in different locations or situations that require simultaneous charging access, compared with split-based charging systems.
Charging hubs such as those designed for desks or walls solve multi-device charging by centralizing power delivery, but they are less portable and do not address scenarios where users move between locations with their charging needs throughout the day, unlike portable split power solutions available.
SharePower occupies a middle ground between these approaches, combining portability with shared usability, making it more relevant for mobile households, travel partners, and flexible living arrangements where charging needs change frequently and unpredictably, especially in modern connected homes and on-the-go lifestyles today.
Should you buy it for households?
Whether SharePower is the right choice depends largely on how often a household needs to charge multiple devices simultaneously, especially for families and frequent travelers, where mobility and shared access matter more than maximum charging capacity alone.
It is most useful for families, roommates, or travel companions who frequently share charging responsibilities and move between environments where carrying two separate power banks would be inconvenient or redundant for everyday device management, especially in shared homes and travel scenarios, for overall efficiency.
For solo users who rarely need to share charging equipment, a traditional high-capacity power bank may still be simpler and more cost-effective, but the split design offers clear advantages when coordination between multiple users is a regular requirement in shared household environments.
TL;DR
- Nimble SharePower is a 10,000 mAh modular power bank that separates into 2 independent 5,000 mAh chargers.
- In Share Mode, each module provides up to 20 W of USB-C PD output. In Stack Mode, the joined unit delivers up to 35 W of total output when charging 3 devices.
- The primary module has a foldaway USB-C connector and a charge-percentage display. The secondary module has an integrated lanyard-style USB-C cable and LED indicators. Both modules also include an additional USB-C port.
- The split design is most useful for families, roommates and travel companions who regularly need portable charging in different locations. Solo users who prioritize greater capacity or more powerful laptop charging may prefer a conventional power bank.
