When it comes to wall chargers, the choices can feel overwhelming. Two popular options from Nimble are the WALLY Stretch 45W and the WALLY SubNano 30W. Both are compact, sustainable, and reliable, but they serve slightly different purposes. In this comparison, we'll break down the key differences to help you decide which one fits your charging needs best.
Whether you're a frequent traveler, a multi-device user, or someone who just wants a dependable daily charger, understanding the nuances between these two models is essential. Let's dive into the details.
Design and Portability
The WALLY Stretch 45W features a unique retractable cable design, which makes it incredibly convenient for on-the-go use. No more tangled cords in your bag – just pull out the length you need and retract it when done. This design also saves space, making it a great travel companion.
On the other hand, the WALLY SubNano 30W is all about minimalism. It's one of the smallest wall chargers in Nimble's lineup, with a compact body that plugs directly into the wall without any cable clutter. Its tiny footprint is perfect for those who want a charger that disappears into their setup.
- WALLY Stretch 45W: Retractable cable, larger but more versatile
- WALLY SubNano 30W: Ultra-compact, no cable, fits easily in a pocket
Charging Speed and Power
The most significant difference is the power output. The WALLY Stretch 45W delivers 45W of power, which is ideal for charging larger devices like tablets, laptops, and even some ultrabooks. It can fast-charge a smartphone at full speed while still having enough headroom to power a tablet simultaneously.
The WALLY SubNano 30W, while less powerful, still provides 30W of fast charging – enough to quickly charge most smartphones and small tablets. It's a great choice if you primarily charge your phone and occasionally a tablet, and you don't need to power larger electronics.
- 45W: Suitable for laptops, tablets, and fast-charging smartphones
- 30W: Ideal for smartphones and small tablets, more compact
Ports and Compatibility
Both chargers feature USB-C ports, which are becoming the universal standard. The WALLY Stretch 45W includes a built-in USB-C cable, so you don't need to carry an extra one. It's a one-piece solution that's hard to beat in terms of convenience.
The WALLY SubNano 30W has a single USB-C port, meaning you'll need to bring your own cable. However, this keeps the charger incredibly small and light. If you already own a high-quality USB-C cable, like the USB-C to USB-C Cable from Nimble, this might be all you need.

- WALLY Stretch 45W: Built-in USB-C cable, no extra cable needed
- WALLY SubNano 30W: Single USB-C port, requires separate cable
Sustainability and Build Quality
Nimble is known for its commitment to sustainability, and both chargers reflect that. They are made with recycled plastics and come in eco-friendly packaging. You can feel good about your purchase knowing that it supports a greener planet.
In terms of build quality, both chargers are sturdy and durable. The WALLY Stretch 45W has a robust retractable mechanism that should withstand daily use, while the WALLY SubNano 30W's solid construction ensures it will hold up well in a bag or pocket.

Which One Should You Choose?
Your choice ultimately depends on your charging habits. If you frequently charge multiple devices or need to power a laptop, the WALLY Stretch 45W is the clear winner. Its built-in cable and higher wattage make it a versatile all-in-one solution.
If you prefer a minimalist setup and only charge your smartphone and maybe a tablet, the WALLY SubNano 30W is perfect. Its tiny size means you'll barely notice it's there, yet it still delivers fast charging speeds.
- Choose WALLY Stretch 45W for laptop charging and multi-device use
- Choose WALLY SubNano 30W for a pocket-sized charger for phones and small tablets
Both the WALLY Stretch 45W and WALLY SubNano 30W are excellent choices, each with its own strengths. Think about your daily routine and what devices you need to charge. If you value convenience and power, go for the WALLY Stretch 45W. If portability is your top priority, the WALLY SubNano 30W won't disappoint. Whichever you choose, you're getting a sustainable, high-quality charger that will keep your devices powered up.
