Up to 1.58 GPM from a 40,000 BTU burner

That's the maximum flow the listing states, and headline flows are usually quoted at a mild temperature rise. At 2 GPM a shower (our calculator's figure), that's one person at a time: the kids, then the dog, then you.

What it has going for it

What changes at the campsite

Runs on a 20 lb tank. Screw it to the tank, hook up a garden hose, drop in the batteries for the igniter and you have a hot rinse at the campsite, the barn or the beach house. Outdoors only: it burns propane right there with no vent.

Freeze protection. Stated in the listing. Useful in a garage, a crawl space or a cabin that sits empty in winter, as long as the unit keeps power.

Campsite or backyard shower?

At the campsite: it runs off a 20 lb tank, the igniter runs on batteries, so it needs no outlet, it starts from 2.5 PSI of water pressure and it weighs 12 lb, per the listing. That pressure is within reach of a 12 V RV pump.

In the backyard: a garden hose and a 20 lb tank are all it needs. Its spot is in the open air, out of the wind; a shed, a tent or a closed stall is out.

Great for you if…

You need one shower or one sink at a time, not the whole house
Camping, the RV or an outdoor shower is the plan
It will live in a garage, a cabin or another cold spot

Skip it if…

You want something to mount inside the house: this one runs outdoors only

What Amzgachfktch promises

The seller states, word for word, in the Amzgachfktch 1.58 GPM Portable Propane listing:

6L portable water heater product size 11.8 (L) x 5.3(W) x 17.3 (H) inches, only weight 12lb. The compact design is suitable for carrying on the go.
Low water pressure start up, just need 2.5 PSI of water pressure to start.
This unit requires a minimum 2.5 PSI starting pressure to operate properly.
The camping water heater runs on a standard 20 lb. liquid propane tank and is equipped with an electronic ignition powered by two D-cell batteries.

That's the seller talking, not us. No listing tells you how it copes with 42 °F water at 6:45 in the morning.

Price and cost per GPM of stated flow

$103.99 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each GPM of stated maximum flow works out at about $65.82 (price ÷ stated GPM, our arithmetic). That puts it in the cheaper third of the 7 portable propane water heaters we have a price and a stated flow for.

Count a 20 lb propane tank if you don't have one, and a hose to reach the water.

Our take

The verdict

We like the Amzgachfktch 1.58 GPM Portable Propane for up to 1.58 GPM and a grab-and-go propane heater. No buyer has reviewed it yet, so our 7.3/10 comes from the spec sheet alone. The catch with this Amzgachfktch portable propane water heater: no word on the warranty. We'd pick the Amzgachfktch if you need one shower or one sink at a time, not the whole house; otherwise, put it next to the CAMPLUX 5L Portable Propane (1.32 GPM) first.

Living with it

Setup

Tank, regulator, garden hose, batteries for the igniter: that is the whole install. Pick a spot in the open air, out of the wind.

The first rinse

Open the water, let the burner light, then set the temperature. It needs at least 2.5 PSI to start, per the listing. The shower head is in the box, per the listing.

Between trips

Drain it, disconnect the tank, and store it dry. A unit left full in a cold shed can crack.

The one thing we'd check first

Before the Amzgachfktch 1.58 GPM Portable Propane ships, check your water pressure: it needs at least 2.5 PSI to fire up, so check your pump or your hose bib.

Before you buy

Water pressure

It starts from 2.5 PSI, per the listing. A garden hose off a house tap is usually plenty; an RV pump or a gravity tank is worth checking first.

The tank and the hose

It is made for a 20 lb tank. Check that the regulator and the gas hose come in the box, and keep a spare tank for a long weekend.

Where it runs

Outdoors only, with open air around it. Never in a tent, a camper, a garage or a closed shower stall: it burns propane right there and makes carbon monoxide.

Before the frost

Drain it after the last trip of the season. Water left inside can freeze and crack the heat exchanger. Our natural gas vs propane guide covers propane setups.

How it compares

How the Amzgachfktch 1.58 GPM Portable Propane stacks up against the closest alternative, the CAMPLUX 5L Portable Propane (1.32 GPM).

Criterion	Amzgachfktch 1.58 GPM Portable Propane	CAMPLUX 5L Portable Propane, 1.32 GPM
Our rating	7.3/10	7.3/10
Max flow	1.58 GPM	1.32 GPM
Gas input	40,000 BTU/h	Not stated

Both score 7.3/10. The Amzgachfktch 1.58 GPM Portable Propane brings more flow (1.58 GPM) and a bigger burner (40,000 BTU/h), so it has the edge on paper.

Frequently asked questions

Is the Amzgachfktch 1.58 GPM Portable Propane any good?

We rate it 7.3/10 (good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How much hot water can the Amzgachfktch 1.58 GPM Portable Propane deliver?

The listing states a maximum flow of 1.58 GPM and a gas input of 40,000 BTU/h. The headline flow is a mild-weather number: with cold winter water coming in, the same unit gives you less. Read the maker's flow chart at your winter rise, or let our flow-rate calculator do the sums.

Can the Amzgachfktch 1.58 GPM Portable Propane be installed indoors?

No. It is a portable propane unit with no vent connection, so it belongs outdoors with air all round: never in a closed room, a tent or a vehicle.

What do you get with the Amzgachfktch 1.58 GPM Portable Propane?

Its listing states up to 1.58 GPM, hot water from a 20 lb propane tank and freeze protection. These are the seller's figures, not our measurements: how steady the temperature is in your shower and how it copes with your winter water can't be read from a listing.

What should I check before ordering the Amzgachfktch 1.58 GPM Portable Propane?

Water pressure: it starts from 2.5 PSI, per the listing. A garden hose off a house tap is usually plenty; an RV pump or a gravity tank is worth checking first. The tank and the hose: it is made for a 20 lb tank. Check that the regulator and the gas hose come in the box, and keep a spare tank for a long weekend. Where it runs: outdoors only, with open air around it. Never in a tent, a camper, a garage or a closed shower stall: it burns propane right there and makes carbon monoxide. Before the frost: drain it after the last trip of the season. Water left inside can freeze and crack the heat exchanger. Our natural gas vs propane guide covers propane setups.

Where can I buy the Amzgachfktch 1.58 GPM Portable Propane?
