At first glance, a built-in USB charger in a suitcase sounds like a useful feature. But when examined closely – through the lens of airline rules, battery lifespan, and the realities of travel – the convenience starts to fade.
Unlike Away or July, Monos made a deliberate choice not to include built-in USB battery packs in its luggage. This guide explains why – and why investing in high-quality components that last a lifetime is a better use of that same engineering space.

The short answer
Built-in USB chargers were popular when they first appeared – but they have three practical issues: travellers still have to carry their own cable, batteries degrade within a year, and airlines often require the battery to be removed before boarding. A separate portable charger is more flexible, more reliable, and usually more useful day to day.
Reason 1 – The cable problem
A built-in USB port does not solve the real charging challenge. Travellers still need to carry their own USB cable to connect a phone, tablet, or laptop to the suitcase. If the cable is being carried anyway, the question becomes simple – why not carry a standalone portable charger that already includes the cable?
A portable charger is more flexible – it can be used anywhere, not just near the suitcase
It can be used on the plane, in a café, or at a hotel without unzipping the suitcase
It can be upgraded over time as charging standards evolve (USB-C, higher wattages, fast charging)
A suitcase is a travel tool. A charger is an electronics accessory. Combining them often means compromising both.
Reason 2 – Batteries degrade before the suitcase does
Lithium-ion batteries have a finite lifespan. Most begin to noticeably deteriorate within the first year of use – losing capacity and charging performance long before a well-built suitcase shows meaningful wear.
That creates a mismatch. A premium suitcase is designed to last for years – wheels, handle, shell, interiors, closures. A built-in battery is designed to last a fraction of that time. When the battery fails, the integrated system becomes a feature that no longer works – and replacing it can be difficult or impossible.
The trade-off: instead of dedicating space, weight, and engineering budget to a component with a short lifespan, that investment can go into the components travellers feel every day – handle stability, wheels, interiors, and shell durability.

Reason 3 – Airline and FAA rules keep changing
Aviation safety rules around lithium batteries are strict, and they continue to evolve. On many airlines, lithium batteries in checked luggage are restricted or prohibited – which means travellers with built-in USB chargers are often required to remove the battery before the bag is checked.
The removal process creates friction:
Travellers must remember to remove the battery at the gate or check-in desk
Forgetting can lead to delays, inspections, or the bag being pulled aside
Policies vary by airline and can change without much notice
Regional rules (domestic, international, transiting countries) may all differ
A feature that requires constant attention to stay compliant is often more stress than convenience. A portable charger, by contrast, simply travels in a personal item – which is where airlines prefer lithium batteries to be anyway.
What Monos invests in instead
Skipping a built-in battery allows more focus on the parts of a suitcase that travellers feel every day – the components that are designed to last as long as the suitcase itself.
