The short answer on power inverter vs converter charger: a power inverter converts DC battery power into AC for appliances, while the converter charger examples here are international plug adapters that explicitly do not convert voltage. Pick the inverter side if you need 220W of AC from a Milwaukee 18V or DeWalt 20V tool battery off-grid; pick the adapter side if you need to plug devices in across 200 or more countries. We compared the 2 Azocek 220W inverters and the 2 travel adapters on what each listing states: function, output, USB charging, protections and warranty. The inverter pair wins on AC output; the adapter pair wins on portability, and the voltage-conversion question is settled by the listings themselves.

Specifications are manufacturer rated as listed, collected 21 October 2026.
What each side does
This is the clearest gap. The 2 Azocek units convert 18V or 20V DC from a tool battery into 110 to 120V AC at 220W, with a 250W peak on the Milwaukee version, and both state a modified sine wave. The NEWVANGA and Anker adapters do not convert voltage at all: the NEWVANGA states it does NOT convert electrical voltage, and the Anker states it is not a voltage converter. Both adapters fit foreign plugs and add USB charging, with the NEWVANGA accepting plugs from more than 200 countries through 5 input plugs and the Anker working in 200 or more countries with Type A, C, G and I plugs.
Power and output
The inverter side is the only side with AC output from a battery. The Azocek Milwaukee version states 220W DC to AC conversion with a 250W peak, one AC outlet, two 18W USB QC ports and one 30W PD Type-C port. The Azocek DeWalt version states 220W with the same port layout. The adapter side passes wall power through: the NEWVANGA states 880W max at 110V and 1920W at 240V with 100 to 240V input, plus a 20W/3A USB-C PD3.0 port, and the Anker states 20W USB total or 15W shared across its USB ports with a 6A maximum. Neither side states a battery figure for itself: the Azocek pair needs the tool battery, sold separately.
Travel and safety
The adapter side is built for luggage. The NEWVANGA weighs 3.2 ounces at 3.0 by 1.9 by 1.5 inches, and the Anker 3.77 ounces at 3.39 by 1.97 by 0.98 inches with foldable pins. The Azocek pair states no weight figure; both add a 400LM LED work light with 3 brightness levels, a strobe function and a 90-degree adjustable angle. On protections, the Azocek pair lists short circuit, overcurrent, low voltage, overheating, overload and over-discharge protection with a cooling fan, plus UL and CE on the Milwaukee version and UL on the DeWalt version. The NEWVANGA lists dual 8A fuses, safety shutters, over-current, over-voltage, short-circuit and surge protection. The Anker lists smart temperature control and a 2-pin design.
What the listings leave unclear
The NEWVANGA warranty description lists only “1” with no unit, so no clear warranty term is stated. The Azocek DeWalt title says 20V while the bullets state compatibility with DeWalt 18V and 20V batteries; the spec table lists 20V input. The Azocek Milwaukee version lists “97,22 %” as standby power shutoff, a figure the listing does not explain. Neither Azocek listing states a weight.

Safety and Warranty
What this listing states. UL and CE specifications met stated, with 6 stated protections and a cooling fan, so safety scores 7 of 10. 1-year warranty stated. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 2 of 5. See How We Pick.
Inverter limits. Stay within the stated continuous watts (surge watts last only a moment), use the cable size and fuse the manual gives, ventilate it, and never connect an inverter to home wiring yourself; that is work for a licensed electrician.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For these devices, safety means the protections and certifications the listing names: UL and CE with 6 protections on the Azocek pair, dual 8A fuses and surge protection on the NEWVANGA, and smart temperature control on the Anker. Three of the 4 state a warranty term, 1 year or 18 months; the NEWVANGA warranty description lists only “1” with no unit. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Azocek 220W Milwaukee | 9.6 | 28 | 20 | 20 | 7 | 2 |
| Azocek 220W DeWalt | 9.6 | 28 | 20 | 20 | 7 | 2 |
| Anker Nano Travel Adapter | 9.5 | 26 | 21 | 20 | 5 | 2 |
| NEWVANGA Travel Adapter | 9.5 | 26 | 20 | 20 | 5 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Power inverter vs converter charger: which should you choose?
Choose a power inverter if the job is AC power away from an outlet: the Azocek Milwaukee version suits owners of Milwaukee 18V batteries, and the Azocek DeWalt version suits DeWalt 20V owners, both with 220W, USB fast charging and a 400LM work light. Choose a travel adapter if the job is charging abroad: the Anker Nano suits minimalists with 20W USB and an 18-month warranty, and the NEWVANGA suits multi-device travelers with 5 input plugs and GaN PD3.0. Neither adapter converts voltage, so a dual-voltage device is still required abroad.

| If you need | Look at |
|---|---|
| AC from a Milwaukee 18V battery | Azocek 220W Milwaukee, 220W, 250W peak |
| AC from a DeWalt 20V battery | Azocek 220W DeWalt, 220W |
| Smallest travel adapter | Anker Nano, 3.77 oz, 18-month warranty |
| Most plug types in one adapter | NEWVANGA, 5 input plugs, 200+ countries |
Sizing Notes
- Match the function to the job: DC to AC conversion on the Azocek pair; plug fit plus USB on the adapter pair, with no voltage conversion.
- Match output to the load: 220W AC on the Azocek pair against phones, laptops and tablets; 20W USB on the adapter pair against small devices.
- Check the battery: the Azocek pair needs a Milwaukee 18V or DeWalt 20V battery, sold separately.
- Check protections: UL and CE with 6 protections on the Azocek pair; dual 8A fuses and surge protection on the NEWVANGA; smart temperature control on the Anker.
- Check warranty lines before ordering: 1 year on the Azocek pair, 18 months on the Anker, no clear term on the NEWVANGA.
FAQ: power away from the grid
Do the converter charger examples convert voltage?
No. The NEWVANGA states it does NOT convert electrical voltage, and the Anker states it is not a voltage converter. Both adapt plugs and add USB charging only.
Which side runs AC appliances off-grid?
The inverter side. The Azocek Milwaukee and DeWalt versions convert 18V or 20V DC from a tool battery into 110 to 120V AC at 220W. The batteries are sold separately.
Which device states the most protections?
The Azocek pair, with short circuit, overcurrent, low voltage, overheating, overload and over-discharge protection plus a cooling fan, and UL and CE on the Milwaukee version. The NEWVANGA lists dual 8A fuses and surge protection, and the Anker lists smart temperature control.
Which has the longest stated warranty?
The Anker at 18 months. The 2 Azocek inverters state 1 year, and the NEWVANGA warranty description lists only “1” with no unit.
Which is the smallest?
The NEWVANGA at 3.2 ounces and 3.0 by 1.9 by 1.5 inches, then the Anker at 3.77 ounces. Neither Azocek listing states a weight.
