Short answer: buy the Nanopresso if you want a cheap, pocketable pump for decent coffee on the go, and buy the Picopresso if you want a real bottomless-portafilter espresso setup that pulls cafe-grade shots. Both cap out at 18 bar and hold an 80 ml water tank, but the Picopresso takes an 18 g dose in a 52 mm basket while the Nanopresso runs 8 g in a pressurized basket. Prices come straight off Wacaco: the Nanopresso is $64.90 and the Picopresso is $129.90.
What actually separates them
These are both hand-powered espresso makers with no built-in heater, so you bring your own hot water either way. The difference is the extraction path. The Nanopresso uses a pump knob and a pressurized filter basket, which is forgiving: it builds pressure for you and hides a mediocre grind or an uneven tamp. That is why it is the one people toss in a backpack. Wacaco lists it at 336 g and 62 x 71 x 156 mm, with an integrated cup that clicks over the body.
The Picopresso is the enthusiast tool. It swaps the pump for a manual piston and a proper 52 mm stainless basket with a naked (bottomless) portafilter, so you can watch the extraction and diagnose channeling like you would on a lever machine. It ships with a tamper, a distribution tool, a funnel, and a double basket, which tells you the intent: this is a portable barista rig, not a camping gadget. The tradeoff is effort. Wacaco notes you need roughly 13 kg of force at peak pressure, versus the Nanopresso's easier pump action. The Picopresso is also chunkier at 350 g and 71 x 78 x 106 mm, so it is shorter and wider, more of a puck than a wand.
Dose is the tell. Eight grams gives the Nanopresso a single-ish shot, and you can push it to 16 g with Wacaco's add-on cup. The Picopresso's 18 g basket is a true double, which is why the coffee comes out heavier and syrupier with the kind of crema you expect from a cafe. If you are chasing flavor, the bigger basket and the real tamp workflow matter more than the shared 18 bar number.

Which one to buy
Pick the Nanopresso if the job is coffee away from a machine and you want low fuss for half the money. Pick the Picopresso if espresso quality is the point and you already grind fresh, weigh your dose, and want to see the shot through a bottomless basket. Neither heats water, so on either one you preheat the group and preinfuse before you commit to the full pull.

FAQ
Is the Picopresso worth double the price of the Nanopresso? If you care about shot quality, yes. The 18 g basket and naked portafilter pull true double espresso with crema, while the Nanopresso's 8 g pressurized basket is built for convenience over flavor.
Do either of them heat water? No. Both the Nanopresso and Picopresso have an 80 ml tank but no heater, so you add your own hot water before pulling a shot.
Which is more portable? The Nanopresso at 336 g is lighter and less demanding to operate, and it packs its own cup. The Picopresso is only 14 g heavier but wider, and it needs about 13 kg of force plus separate accessories.
