Your Dymo label maker suddenly won't turn on. If you're shopping for label makers supplies, the charger is usually the first suspect. The tricky part is that replacement adapters look nearly identical online: same black round-tip plug, same three-foot cord, same wide input range. The real difference is which label maker each one is made to match. This head-to-head compares the AC Adapter for Dymo LetraTag LT-100H LT-100T Label Makers Charger Power with the AC DC Adapter Charger for Dymo 40077 Label Makers Switching Power Supply Cord so you can pick the one that fits your machine.
Quick verdict
Both are new, non-OEM AC/DC adapters with round-tip output, a three-foot cord, and an input voltage span of 100-240V. The LetraTag adapter lists for $1.75 less than the 40077 adapter, but price only matters after you match the charger to your label maker. If you have a Dymo LetraTag LT-100H or LT-100T, choose the lower-priced adapter. If you have a Dymo 40077, the other adapter is the one named for your machine.

Where each product wins
Where the LetraTag adapter wins: The AC Adapter for Dymo LetraTag LT-100H LT-100T Label Makers Charger Power is the model-specific choice for those two LetraTag label makers. It also comes in at the lower of the two listed prices, so if you own an LT-100H or LT-100T, you can get the matching charger for less. The only real homework is confirming the plug type and output voltage before ordering.
Where the 40077 adapter wins: The AC DC Adapter Charger for Dymo 40077 Label Makers Switching Power Supply Cord is the one that names the Dymo 40077 directly. If your label maker is a 40077, this is the adapter that keeps the compatibility match front and center. It carries the higher of the two listed prices, which makes sense when your machine actually needs the 40077-compatible input.
Product notes
AC Adapter for Dymo LetraTag LT-100H LT-100T Label Makers Charger Power
This is the adapter to order when your label maker is a Dymo LetraTag LT-100H or LT-100T. It arrives as a new AC/DC replacement, and it's built as a compatible substitute rather than an original Dymo part. Before you plug it in, double-check that the output voltage and plug type match your device. Plug appearance can vary by production batch, so a quick visual check against your current charger is a good idea. If the LT-100H or LT-100T is what you own, this adapter gives you the exact model match at a lower listed price than the 40077 version.
AC DC Adapter Charger for Dymo 40077 Label Makers Switching Power Supply Cord
If your machine is a Dymo 40077, this is the adapter to grab. It's a new AC/DC switching adapter, and the name spells out the 40077 compatibility. Like the LetraTag version, it's a non-OEM part, so you should verify your device's voltage and plug shape before use. The same production-batch variation applies, meaning the plug or label may look different from one batch to the next. When you already know your label maker is the 40077, this charger keeps the purchase model-specific, even though it costs a bit more than the LetraTag adapter.
