A travel tech kit is the same for almost everyone: a laptop or tablet, a phone, a charger or two, a power bank, a nest of cables and, on international trips, an adapter. It is also the part of the bag people pack worst, because it arrives in the bag the way it left the desk: loose. This guide is the method, in three parts. The rules, which are not negotiable and mostly concern batteries. The placement, which decides whether the laptop survives and whether security takes two minutes or ten. And the organizer, which is the difference between a kit and a tangle.
The rules first: batteries fly in the cabin
The FAA’s rule is the one that matters, and it is simple. Spare lithium batteries, power banks and portable chargers must be carried in the cabin, never in checked baggage.The rule is written around spares and banks, but the practical answer for every device is the same: it flies in the cabin with you. Rechargeable lithium-ion batteries up to 100 Wh need no approval; 101 to 160 Wh need the airline’s approval and are limited to two spares; above 160 Wh is forbidden. The watt-hour figure is printed on every power bank, and nearly every consumer bank is under 100 Wh. Terminals must be protected from short circuit, which in practice means a bank in a case or a pocket of its own rather than loose against a bundle of keys.
TSA’s guidance says the same thing from the screening side: power banks in carry-on bags, spare batteries prohibited in checked ones. The full rules, including what airlines add on top, are in power banks on planes.
The other rule at the checkpoint is about the laptop. At standard TSA screening, laptops come out of the bag and go in their own bin. TSA PreCheck travelers leave them in. That one line decides how the laptop should be packed, which is the next section.
Where each thing goes
The laptop
Against the back panel, in the padded sleeve, suspended off the bottom of the bag. Two reasons: weight close to your spine carries best, and a laptop that does not touch the floor of the bag is a laptop that survives the bag being dropped. Every travel pack we recommend for laptop carry publishes a sleeve size, and that size must be at least your laptop’s; the picks are on the laptop backpacks page. Some work bags add a lay-flat compartment, a laptop section that unzips fully open so the machine can be scanned in place, which some checkpoints accept and which turns a ten-minute lane into a two-minute one for a traveler without PreCheck. The MATEIN 17-inch bag on our business travel page is the budget example.
The tablet and the e-reader
In the same sleeve as the laptop, or the secondary sleeve if the bag has one, screen facing the laptop’s lid so neither screen faces the outside of the bag. Whether a tablet comes out at screening varies by checkpoint, so pack it where it is easy to reach.
The power bank and the charger
These are the heavy, awkward items, and they go in the tech organizer’s padded or wide-strap side, not in the cable loops. The organizer then goes flat against the laptop sleeve, close to your spine, where the heaviest small item you carry belongs; in an outer pocket it levers the load away from your back. A power bank left loose in the main compartment migrates to the bottom and lands on the laptop. Keep one cable and the bank itself reachable for the flight, and the rest of the case packed.
The cables
One per connector type, plus a spare of the one you use most, coiled loosely and held in their own loops. Tight coiling is what breaks cables at the plug; a loose coil the size of your palm, secured with its own tie, is what lasts. Label the ends if two look alike.
The adapter
One universal adapter, or one for the destination, in the organizer with the charger. Do not bring a converter unless you are carrying something with a motor or a heating element; laptop, phone and camera chargers are dual-voltage and need only the plug shape.
Consolidate before you pack
The kit that packs well is the kit that is small, and most of the size is duplication. One multi-port USB-C charger that covers the laptop and the phone replaces two bricks and a wall wart. One USB-C cable does phone, tablet and most laptops; a second covers the camera or the headphones. The power bank should be the only battery you carry besides the ones inside devices. Laid out on a table, a consolidated kit is a charger, a bank, three cables, an adapter and headphones, and that fits a case the size of a paperback.
The organizer, and why it is not optional
A cable case is the cheapest organizer that changes how a bag works. Without one, the cables go in a pocket, the pocket becomes a knot, and the knot gets dumped on a hotel bed every night to find the one you need. With one, the whole kit comes out as a single flat panel, gets used, and goes back. The criteria are layout and shape: elastic loops for cables, a separate side or wide straps for bricks and the bank, and a case that closes flat so it slides into a pack rather than wedging.
Judged on those, these are the three we would build a kit around: the flat dual-compartment case for most people, the budget case that covers a whole kit for very little, and the one built for chunky plugs and adapters.
#1The default: cables on one side, bricks on the other, closes flat
tomtoc Electronic Organizer Travel Case (Dual Compartment)
The organizer to buy if you carry both cables and bricks. The dual-compartment layout gives thin cables their own elastic panel and keeps chargers, a power bank or a mouse in a separate padded side, so the case closes flat instead of bulging into a lump. It costs a little more than the cheap pouches and earns it in layout.
Strengths
- +Two compartments keep flat cables and chunky bricks from fighting each other
- +Padded shell protects a power bank or hard drive
- +Closes flat, so it slides into a pack rather than wedging
Trade-offs
- −Bigger than a single-layer pouch — overkill for one phone cable
- −Costs more than the budget cases that do 80% of the job

Fit note. Dual-compartment is the spec worth paying for. Single-layer cases force a fat charger to sit on top of flat cables, which is what makes a tech pouch bulge and stop packing flat against a laptop sleeve.

#2The budget case: a full kit's worth of loops for very little
BAGSMART Large Electronic Organizer Travel Case
The value pick, and the one most people should start with. A large double-sided case with enough elastic loops and mesh to swallow a full travel tech kit, at a price that makes the decision easy. Build is fine rather than lovely — the zips are the part that will eventually date it.
Strengths
- +Large enough for a full kit — chargers, cables, adapters, drives
- +Double-sided layout with plenty of loops and mesh
- +Costs very little for how much order it buys
Trade-offs
- −Zips and fabric are serviceable, not premium
- −Large size is wasted if you only carry a phone cable and an adapter

Fit note. Buy the size that matches your kit, not the biggest one. A large case that travels half-empty wastes more space in a 35L pack than the disorder it was bought to fix.

#3The adapter case: wide straps for chunky plugs and power banks
BUBM Double Layer Electronic Accessories Organizer (Medium)
The one that handles awkward, chunky items. BUBM's double-layer case is built around wide elastic straps rather than skinny cable loops, so plugs, power bricks and battery packs actually strap down instead of rattling loose. The medium is sized to take a tablet-sized device alongside the kit.
Strengths
- +Wide straps hold chunky bricks and adapters that slip out of cable loops
- +Double-layer design keeps two kits separated in one case
- +Structured shell holds its shape in a packed bag
Trade-offs
- −Structured build takes up more room than a soft pouch
- −More organizer than a light packer needs

Fit note. Elastic loop width is the quiet spec here. Cases built for thin cables can't hold a chunky international adapter, and an adapter loose in a pack is the item people most often arrive without.

The premium alternative is the Peak Design Tech Pouch, with origami-style shelves that expand as you fill them and a cable pass-through for charging with the pouch closed; it costs several times what the cases above do, and whether it is worth it depends on how often you open your kit. The two philosophies are compared in tomtoc vs Peak Design Tech Pouch, and the whole field is in best tech organizers.
The security lane, in order
- Laptop out of its sleeve and into its own bin, unless you have PreCheck.
- The liquids bag out of the front pocket, per the 3-1-1 rule. The tech case can stay in the bag.
- Phone, watch and anything metal into the bin with the laptop, not into a pocket you will forget.
- Power bank stays in the bag; it is a cabin item, which is the point.
- On the far side, laptop back in the sleeve first, then the liquids, then zip. Do it at the table, not walking away.
On the plane and at the far end
Charge everything the night before and board with a full power bank; it is the only guarantee of a working phone on arrival, and it saves the gate-outlet hunt. Keep the headphones and the bank in the pocket you can reach with the bag under the seat, which is the same pocket as the documents in our personal item packing list. At the hotel, the kit comes out of the bag as one case and goes onto the desk, and the laptop goes in the safe or stays in the bag against the wall, not on the bed where it will be sat on. Where the tech sits in the wider load order, and why heavy items belong against the back panel, is in how to pack a travel backpack.
